Betahistine: a retrospective synopsis of safety data.
Jeck-Thole S, Wagner W.
Solvay Pharmaceuticals, Hannover, Germany.

Betahistine is a structural analogue of histamine that is prescribed for the treatment of vestibular disorders such as Meniere's disease and the symptomatic treatment of vertigo. It is estimated from sales information that >130 million patients have been exposed to the drug since its registration in 1968. In this review we analyse the safety profile of betahistine based on data obtained during >35 years of worldwide postmarketing surveillance.Until 31 December 2005, 554 adverse drug reaction (ADR) reports with 994 individual signs and symptoms were received by the marketing authorisation holder from worldwide sources and were reviewed and evaluated. Signs and symptoms of cutaneous hypersensitivity reactions during betahistine therapy were the most frequently reported complaints. They consisted of usually mild and self-limiting rash, pruritus and urticaria, and all symptoms were reversible after drug discontinuation. Betahistine was reported to be involved in one anaphylactoid reaction and one case of Stevens-Johnson syndrome. Anaphylactic reactions with fatal outcome were not reported.The reports that describe gastrointestinal complaints mostly concern nausea and vomiting or unspecific abdominal pain. These were typically non-serious complaints. Hepatobiliary involvement was reported 25 times, including increases in alkaline phosphatase, gamma-glutamyltransferase, and alanine and aspartate aminotransferase levels. None of the patients concerned developed severe liver failure or died. ADRs related to the nervous system predominantly reveal heterogeneous events that are not suggestive of a specific adverse reaction profile for betahistine. A clinical intolerance to betahistine that gave rise to asthma or bronchospasm was only reported in eight ADRs. A total of three cases of neoplasm have been reported. One case concerned a male patient of unknown age who experienced weight loss, insomnia, impatience and irritability soon after the start of betahistine therapy. An undiagnosed phaeochromocytoma was suspected. The remaining two cases were assessed as being unrelated to betahistine by the reporter. Finally, four deaths have been reported during the course of postmarketing surveillance for betahistine. The reporter assessed the causal relationship to betahistine in two as unrelated, in one as unlikely and the other as unassessable.In summary, clinical and postmarketing studies have revealed a good safety profile of betahistine that was confirmed by the safety surveillance data presented.

Evaluation of booklet-based self-management of symptoms in Meniere disease: a randomized controlled trial.
Yardley L, Kirby S.
School of Psychology, University of Southampton, Highfield, Southampton SO17 1BJ, UK. L.Yardley@soton.ac.uk

OBJECTIVE: This study examined the effectiveness of booklet-based education in vestibular rehabilitation (VR) and symptom control (SC) techniques to manage vertigo and dizziness in Meniere disease. METHODS: Participants (n = 360) were randomized to a waiting list control group or to receive either a VR or an SC self-management booklet. VR involved provoking dizziness in a controlled manner by making repeated head movements in order to promote neurological and psychological habituation. SC involved using applied relaxation, challenging negative beliefs, and lifestyle modification to reduce amplification of dizziness by anxiety. Subjective improvement in health, enablement (ability to understand and cope with symptoms), and adherence were measured at 3 and 6 months. Symptoms, handicap, anxiety and depression, and negative beliefs about symptoms were assessed pretreatment and at 3 and 6 months. RESULTS: At 6-month follow-up, 45 (37.5%) of the VR group and 47 (39.2%) of the SC group reported improvement compared with 19 (15.8%) controls; the relative probability of improvement compared with controls was 2.37 (95% confidence interval [CI], 1.48-3.80) for VR and 2.47 (95% CI, 1.55-3.95) for SC. Both intervention groups reported greater enablement than controls (p < .001, d > 0.70). At 3 months, the VR group had reduced symptoms, anxiety, handicap, and negative beliefs about dizziness; the SC group had reduced handicap; but the control group showed no improvement. Reported adherence levels were low and strongly related to outcome. CONCLUSIONS: Self-management booklets offer an inexpensive and easily disseminated means of helping people with Meniere disease to cope with dizziness symptoms.

Diaz RC, Larouere MJ, Bojrab DI, Zappia JJ, Sargent EW, Shaia WT.
*Michigan Ear Institute, Farmington Hills, Michigan, U.S.A.; daggerOtology, Neurotology, and Skull Base Surgery Service, Providence Hospital, Southfield, Michigan, U.S.A.; and double daggerDepartment of Otolaryngology-Head and Neck Surgery, Wayne State University, Detroit, Michigan, U.S.A.

OBJECTIVE:: To examine the impact of surgical labyrinthectomy on quality of life of Meniere's disease patients. STUDY DESIGN:: Cross-sectional survey. SETTING:: Otology subspecialty referral center. PATIENTS:: All patients with Meniere's disease who underwent surgical labyrinthectomy between 1998 and 2004 were selected. Fifty-three patients satisfied inclusion criteria. Completed questionnaires were obtained from 44 patients. INTERVENTION(S):: The Meniere's Disease Outcomes Questionnaire is a disease-specific quality-of-life questionnaire. It was used to assess the quality of life of patients before and after surgical labyrinthectomy. The questionnaire encompasses physical, mental, and social well-being domains of quality of life. MAIN OUTCOME MEASURE(S):: Change in total quality-of-life score was used to assess the overall impact of surgical labyrinthectomy on subjective patient outcome. Individual quality-of-life domains were also assessed. RESULTS:: Forty-three of 44 respondents (98%) had improvement in total score after surgery. The one patient who demonstrated deterioration developed latent contralateral disease. Average preoperative and postoperative scores were 34 +/- 14 and 67 +/- 15, respectively (p < 0.001). All questions showed significant improvement with surgery (p < 0.001) except questions pertaining to memory (no change) and hearing loss (nonsignificant decrease in score). CONCLUSION:: This study comprises the first patient-directed assessment of quality-of-life outcomes in Meniere's disease patients after labyrinthectomy. Despite the disadvantage of hearing loss, patients consistently reported significant improvement in all quality-of-life domains and do not report a significant loss of quality of life in terms of their hearing loss. Surgical labyrinthectomy remains a highly effective treatment for Meniere's disease patients.

Intratympanic gentamicin treatment in Meniere's disease: patients' experiences and outcomes.
Smith WK, Sandooram D, Prinsley PR.
Department of ENT Surgery, Addenbrookes Hospital, Cambridge, UK.

OBJECTIVE: The aim of this study was to assess the experiences and outcomes of patients receiving intratympanic gentamicin treatment for Meniere's disease in Norfolk, UK. DESIGN: This study was based on a retrospective questionnaire survey and a review of patients' medical records. SETTING: Two district hospitals. PARTICIPANTS: All 29 patients treated between 1999 and 2001, with a minimum follow up of two years post-treatment, were included in the study. Twenty-three patients completed the questionnaires (79 per cent response rate). MAIN OUTCOME MEASURES: Glasgow benefit inventory (GBI) and vertigo symptom scale (VSS) scores, plus change in hearing thresholds. RESULTS: The mean GBI total score was +36, indicating substantial improvement in patients' overall quality of life following gentamicin treatment. The VSS scores demonstrated low levels of vertigo or unsteadiness in treated patients. Three patients suffered deterioration in their hearing thresholds following a single injection of gentamicin. However, 96 per cent of responders stated that they would be willing to have such treatment again, if necessary. CONCLUSION: Intratympanic gentamicin treatment ought to be offered to Meniere's patients suffering from disabling vertigo, with the proviso that they be made aware of the possibility of hearing deterioration.

Vertigo: few new spins on a common problem.
Zanni GR, Wick JY.
National Cancer Institute, National Institutes of Health, Bethesda, Maryland, USA.

Vertigo is a common balance deregulation symptom among elders. Its etiology may be peripheral vestibular disease or a central vestibular disorder. Symptom onset, severity, and duration are distinguishing characteristics. The majority of peripheral vestibular disorders include benign paroxysmal positional vertigo, vestibular neuronitis, Meniere's disease, and perilymph fistula. Medication regimen review is necessary to identify possible drug-induced etiology. Treatment options include pharmacotherapy, canalith repositioning procedures, surgery, vestibular rehabilitation therapy, and dietary interventions.

Department of Otolaryngology, Osaka University Medical School, Japan.

OBJECTIVE:: To look for factors relating to the vertigo control and hearing changes after intratympanic injections of gentamicin (GM). STUDY DESIGN:: Prospective. SETTING:: Tertiary referral medical center. PATIENTS:: Twenty-eight patients with intractable Meniere's disease. INTERVENTIONS:: Three intratympanic injections of GM (once per day for three consecutive days). MAIN OUTCOME MEASURES:: Although five patients needed further GM injections or vestibular neurectomy because of poor control (Group I), 23 patients had their vertigo controlled for more than two years without further treatment (Group II). The number of vertigo spells per month, pure-tone audiometry, electrocochleography, caloric response, post-head shake nystagmus, and plasma vasopressin as a stress marker were examined. RESULTS:: Before GM injections, there was no difference in the number of vertigo spells per month between Groups I and II. However, the hearing thresholds were higher in Group I. Hearing improvement, increase in percentage of canal paresis and induction of post-head shake nystagmus were observed after GM injections only in Group II. Even in the 11 patients who showed an improvement in hearing of more than 10 dB (hearing improvement group), percentage of canal paresis was increased after GM. More, premedication plasma vasopressin levels were lower in the hearing improvement group as compared with the hearing loss/no changes group. Four of eight patients became negative for dominant negative summating potential in electrocochleography after GM injections in the hearing improvement group. CONCLUSION:: Our data indicate that the frequency of vertigo is not a key factor in the vertigo control after GM injections, that induction of vestibular damage in the injected ear is essential for the control of vertigo and this effect is mostly pronounced in patients with milder hearing loss, and that hearing improvement is not only a consequence of good vertigo control but also affected by the stress level before treatment.

Alles MJ, der Gaag MA, Stokroos RJ.
Department of Otorhinolaryngology, Head and Neck Surgery, University Hospital Maastricht, P. Debyelaan 25, P.O. Box 5800, 6202 AZ, Maastricht, The Netherlands, RSTO@SKNO.AZM.NL.

To evaluate the value of clinical trials on intratympanic steroid therapy in Meniere's disease (MD), idiopathic sudden sensorineural hearing loss (ISSNHL) and rapidly progressive sensorineural hearing loss (RPSNHL). Medline and Pubmed databases from 1966 to present were searched for clinical studies on intra- or transtympanic (cortico)steroid therapy of MD, ISSNHL and RPSNHL. Results were cross-checked with additional databases to obtain a complete data set. Clinical trials were evaluated on the basis of comparability, internal and external validity. Articles were judged using the following questions: was a randomised double-blind controlled trial performed? Which criteria were used to confirm the diagnosis of MD, ISSNHL, RPSNHL? Which therapy was evaluated? How long was the follow-up? Which criteria were used to evaluate the results? Reliable evidence on the efficiency, optimum dosage and administration schedule of intratympanic steroid therapy in MD, ISSNHL and RPSNHL is lacking, therefore further investigation is required.

Outcome-based assessment of endolymphatic sac decompression for Meniere's disease using the Meniere's disease outcome questionnaire: a review of 90 patients.
Convert C, Franco-Vidal V, Bebear JP, Darrouzet V.
Skull Base Surgery Department, University of Bordeaux, Bordeaux, France.

OBJECTIVE: To evaluate the quality of life (QOL) of patients treated by endolymphatic sac decompression (ELSD) for Meniere's disease (MD) with a dedicated questionnaire, while recording the results of this surgery on vertigo attacks using the American Academy of Otolaryngology-Head and Neck Surgery criteria. STUDY DESIGN: Retrospective case review in a tertiary referral care center. MATERIAL AND METHODS: Ninety patients who have MD were treated by ELSD at our institution between 1986 and 2004. They were sent a 40-question Meniere's Disease QOL dedicated questionnaire (Meniere's Disease Outcome Questionnaire) concerning physical, mental, and social well-being. Five scores out of 100 were calculated (S1-S5): S3 for preoperative QOL score, S4 for postoperative QOL score, S5 for change in QOL score (S5 = S4 - S3), and S1 and S2 representing the answers to two other paired questions about the "overall" feeling of the patients. In parallel, results of ELSD on vertigo attacks and hearing were evaluated using the Academy of Otolaryngology-Head and Neck Surgery criteria. RESULTS: Fifty-nine interpretable answers (65.6%) to the Meniere's Disease Outcome Questionnaire were obtained from 28 men and 31 women (mean age, 56 yr and 9 mo), all suffering from "definite" MD. The mean S3 was 32.5 (range, 9.7-84.7), and the mean S4 was 60.8 (range, 0-98.6). Consecutively, S5 score was 28.3 (range, -34.7 to 77.4). QOL improved in 81.4% of cases with an average duration of follow-up of 57.5 months (range, 4-156 mo) (p < 0.001), worsened in 11.9% and was stable in 6.8%. There was no statistically significant difference as a function of sex (p = 0.7) or length of follow-up (p = 0.6). There was a significant correlation between S1 and S3 (p < 0.0001), and S2 and S4 (p < 0.0001), validating the whole questionnaire. In addition, 71% of satisfactory control of vertigo at 2 years postoperatively was noted. Hearing was improved or unchanged in 79% of cases at 3 months postoperatively. CONCLUSION: These results show that ELSD significantly improves the health of patients. It represents a first-line procedure that preserves the vestibular and afferent structures, unlike vestibular neurotomy and chemical labyrinthectomy, which may be indicated as a second line.

Diuretics for Meniere's disease or syndrome.
Thirlwall AS, Kundu S.
Royal Berkshire Hospital, Ear, Nose & Throat Department, London Road, Reading, UK RG1 5AN. andy_thirlwall@hotmail.com

BACKGROUND: Meniere's disease is a disorder characterised by hearing loss, tinnitus and disabling vertigo. Diuretics are used to try and reduce the severity and frequency of episodes but there is little evidence behind this treatment. OBJECTIVES: To assess the effect of diuretic treatment in patients with Meniere's disease. SEARCH STRATEGY: We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library, Issue 1 2005), MEDLINE (1966 to 2005), EMBASE (1974 to 2005), CINAHL and the metaRegister of Controlled Trials (mRCT) (up to 2005). SELECTION CRITERIA: Randomised controlled trials of diuretic versus placebo in Meniere's patients. DATA COLLECTION AND ANALYSIS: One author identified studies which loosely met the inclusion criteria and full texts were retrieved. Two authors independently applied the inclusion criteria. Seven studies were excluded from the review due to inappropriate study design or absence of randomisation. MAIN RESULTS: There were no trials of high enough quality to meet the standard set for this review. AUTHORS' CONCLUSIONS: There is insufficient good evidence of the effect of diuretics on vertigo, hearing loss, tinnitus or aural fullness in clearly defined Meniere's disease.

Intratympanic Gentamicin for Meniere's disease: effect on quality of life as assessed by Glasgow benefit inventory.
Banerjee AS, Johnson IJ.
Newcastle Balance Centre, Department of Otology, Freeman Hospital, Newcastle upon Tyne, UK.

Objectives: To evaluate patients' quality of life after receiving intratympanic gentamicin as treatment for Meniere's disease.Design: Retrospective study using the Glasgow benefit inventory scale (GBI) questionnaire.Participants: Patients diagnosed with Meniere's disease, according to the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) diagnostic criteria (refractory to medical management), who were treated with intratympanic gentamicin injection.Materials and methods: This retrospective study included all patients diagnosed with Meniere's disease (according to AAO-HNS criteria; refractory to medical management) undergoing gentamicin labyrinthectomy in our unit over the preceding three years. Other causes of hearing loss were ruled out as all patients underwent magnetic resonance imaging, electronystagmography and sway magnetometry. Patients underwent gentamicin infiltration at a concentration of 2 ml of 30 mg/ml and were reviewed six weeks later and received a repeat injection if no benefit was evident. Six months after their last follow up, they were sent a GBI questionnaire. Twenty-one questionnaires were posted, and the response rate was 81 per cent.Results: As per the responses received, the total benefit of intratympanic gentamicin injection was found to be +30.3. The three components of GBI were analysed separately; it was found that general benefit was greatest (+33.3), followed by physical benefit (+28.1) and social benefit (+21.6).Conclusion: This study suggests that gentamicin definitely improves quality of life in patients with Meniere's disease and should be the first line of treatment if medical management fails.

Stokroos R, Olvink MK, Hendrice N, Kingma H.
Department of Otorhinolaryngology-Head and Neck Surgery, University Hospital Maastricht, Maastricht, The Netherlands. rsto@skno.azm.nl

CONCLUSION: Use of the Meniett pressure generator in patients with active Meniere's disease (MD) did not affect labyrinthine function. OBJECTIVE: To investigate whether application of the Meniett pressure generator in patients with active MD significantly affects their labyrinthine function. MATERIAL AND METHODS: We measured hearing and labyrinth sensitivity in patients with established MD according to American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria at five different time periods: at baseline; before ventilation tube placement; before Meniett treatment; immediately after Meniett treatment; and 1 month after cessation of Meniett treatment. RESULTS: A total of 32 patients met the inclusion criteria and were included in the study. They were graded as having definite MD (AAO-HNS stages 2 and 3). No statistically significant changes in labyrinthine function were found during Meniett treatment.

Outcomes in the use of intra-tympanic gentamicin in the treatment of Meniere's disease.
Flanagan S, Mukherjee P, Tonkin J.
Department of Otolaryngology, St Vincent's Hospital, Sydney, New South Wales, Australia.

The pathogenesis of Meniere's disease is associated with a disorder of ionic homeostasis, with the pathologic correlate being endolymphatic hydrops. Despite uncertainty as to its particular mode of action, it is accepted wisdom that intra-tympanic gentamicin has a definite therapeutic role in the control of symptoms in patients who fail to respond to medical therapy. This study reports an evaluation of the efficacy of intra-tympanic gentamicin in the treatment of Meniere's disease and also presents a simple, reliable, safe method of administering gentamicin for this purpose. A retrospective review of 56 patients undergoing intra-tympanic gentamicin treatment for Meniere's disease was conducted. Response to treatment was analysed using a patient survey and examination of pure-tone averages. An overall significant improvement in vertigo symptoms of 81.3 per cent was found. There was a 21.4 per cent rate of significant hearing loss, defined as greater than 10 dB, with an average loss in this group of 18.5 dB. A single dose of gentamicin applied directly to the round window resulted in a high rate of control of vertigo, with acceptably low rates of hearing loss.

Pharmacological advances in the treatment of neuro-otological and eye movement disorders.
Strupp M, Brandt T.
Department of Neurology, University of Munich, Germany. Michael.Strupp@med.uni-muenchen.de

PURPOSE OF REVIEW: First, to describe the current pharmacological treatment options for peripheral and central vestibular, cerebellar, and ocular motor disorders. Second, to identify vestibular and ocular motor disorders in which treatment trials are warranted. RECENT FINDINGS: Peripheral vestibular disorders: In vestibular neuritis recovery of the peripheral vestibular function can be improved by treatment with oral corticosteroids. In Meniere's disease treatment strategies range from low-salt diet, diuretics, and betahistine, to intratympanic injection of corticosteroids or gentamicin. Unfortunately most of the trials on Meniere's disease do not have an up-to-date design. In bilateral vestibulopathy steroids do not seem to improve vestibular function.Central vestibular, cerebellar, and ocular motor disorders: The use of aminopyridines introduced a new therapeutic principle in the treatment of downbeat and upbeat nystagmus and episodic ataxia type 2 (EA2). These potassium channel blockers presumably increase the activity and excitability of cerebellar Purkinje cells, thereby augmenting the inhibitory influence of these cells on vestibular and cerebellar nuclei. A few studies showed that baclofen improves periodic alternating nystagmus, and gabapentin and memantine, pendular nystagmus. Many other eye movement disorders, however, such as ocular flutter, opsoclonus, central positioning, or see-saw nystagmus are still difficult to treat. SUMMARY: Although progress has been made in the treatment of vestibular neuritis, downbeat and upbeat nystagmus, as well as EA2, state-of-the-art trials must still be performed on many vestibular and ocular motor disorders, namely Meniere's disease, bilateral vestibulopathy, vestibular paroxysmia, vestibular migraine, and many forms of central eye movement disorders.

[Local overpressure treatment reduces vestibular symptoms in patients with Meniere's disease--secondary publication. A clinically randomised multicenter double-blind placebo-controlled study]
[Article in Danish]

This investigation was performed to evaluate the efficacy of a new device, the Meniett, in the treatment of Meniere's disease. The device delivers pressure pulses to the middle ear through a ventilating tube in the tympanic membrane. These pressure changes are conveyed to the inner ear, reducing the endolymphatic hydrops. The device is significantly effective in reducing the vestibular symptoms, as compared with the placebo device. Local overpressure treatment is a novel treatment that is non-invasive, non-destructive and safe. It should be offered to patients before more invasive surgical modalities are suggested.

[Vestibular neurotomy versus chemical labyrinthectomy for disabling Meniere disease]
[Article in French]
Morel N, Dumas G, Nguyen DQ, Mohr E, Hitter A, Schmerber S.
Service d'oto-rhino-laryngologie, CHRU Grenoble, 38043 Cedex 09.

OBJECTIVE: To evaluate the efficiency on the vertigos and the impact on the audition of the vestibular neurotomy (VN) and the chemical labyrinthectomy (CL) in patients with severe Meniere's disease, in order to determine the precise place for each technique in treatment algorithm. METHOD: Retrospective study of 71 VN (performed between 1986 and 2003) and 35 CL (performed between 1997 and 2003). These two treatments both aim at obtaining a vestibular deafferentation in order to free definitely the patient of vertigo manifestations. Vestibular results have been assessed by caloric tests performed before and 6 months after treatment. Subjective success was evaluated by searching for recurrent attacks of vertigo and by the AAO-HNS (American Academy of Otolaryngology-Head and Neck Society) scale of subjective evaluation of vertigos (follow-up of 6.4 years after VN and 2.4 years after CL). Pure tone audiometry before treatment and then 6 months later was performed. Complications of two types of treatment were recorded and evaluated. RESULTS: In 90% of the cases after VN and 86% of the cases after CL, caloric tests indicated a strong vestibular hyporeflexy (hypovalence > 90%). Attacks of vertigo reoccurred in 5.6% of the cases when the hyporeflexy was strong and 85.7% of the cases when it was weak. The quality of the vestibular results on vertigo depends on the degree of hypovalence after treatment. An improvement of the AAO-HNS scale have been obtained in 93% of the cases in the NV group and in 81% of the cases in the LC group. Attacks of vertigo were recurrent in 7% of the patients operated on by VN and 11.4% of the patients treated by CL. Mean pure tone auditory thresholds changed from 50.24 dB HL to 55.64 dB HL (p=0.003) in the VN group and from 69.11 dB HL to 74.51 dB HL (p=0.41) in the CL group. Comparison of the variations of the mean pure tone auditory thresholds before treatment and 6 months after the end of the treatment doesn't show any significant difference between the 2 groups (p > 0.05). Impairment of the audition superior to 20 dB HL was observed in 8.5% of the patients of each group. The auditive results are similar in the 2 groups. CONCLUSION: These two methods of treatment can not be strictly compared due to several bias in this study. Indeed more patients were treated by VN with a longer follow-up and only the patients with a class C or D audition according to the criteria of the AAO-HNS could be treated by CL. The VN provides a better control of the vertigos than the CL which is an efficient method of treatment in invalidating Meniere's disease. In all the cases, the quality of the results on vertigos depends on the degree of hypovalence after treatment. The auditive results are similar. Since the results of the two treatments are similar, the simplicity of CL encourages us to broaden the indications and to modify the place of the VN in the therapeutic algorithm of Meniere's disease.

The authors propose the existence of a new entity of autoimmune sensorineural hearing loss on the basis of diagnostic study and treatment experience with a series of 30 patients. Immunological mechanisms play an important role in the pathogenesis and natural course of various inner-ear diseases. Patients may present clinically with symptoms resembling Meniere's disease or even with sudden deafness. Currently, no widely used standard protocol for treatment of this autoimmune sensorineural hearing loss exists. Prompted by such observations, we implemented a protocol using a particular kind of heparin--sodium enoxaparin--with a low molecular weight. Patients were randomly assigned to two groups; to those in the first group, enoxaparin was administered subcutaneously at a dose of 2,000 IU twice daily for 10 days; the patients in the second group were treated with placebo. At the beginning and at the end of the therapy period, the patients were evaluated by instrumental examinations. Specifically excluded were patients with abnormal known coagulation. On discharge, all patients treated with enoxaparin presented both a subjective and objective decrease in symptoms. No patient experienced side effects from this treatment. The results indicate that administration of sodium enoxaparin abates sensorineural hearing loss in patients with autoimmune diseases. The clinical response to therapy can confirm diagnosis.

Department of Otorhinolaryngology, University of Pisa, Italy. a.casani@med.unipi.it

OBJECTIVE: To determine the effects of transtympanic injections, with a mixture composed of gentamicin and fibrin tissue adhesive (FTA), on vestibular function of patients with intractable unilateral Meniere's disease. STUDY DESIGN: This was an open, prospective study. SETTING AND PATIENTS: The study was performed at 2 tertiary referral centers. Twenty-six patients affected by "definite" unilateral Meniere's disease, unresponsive to medical therapy for at least 6 months, were enrolled. INTERVENTION: A buffered gentamicin solution mixed with FTA was injected in the middle ear until the development of bedside vestibular hypofunction signs and/or caloric weakness in the treated ear. MAIN OUTCOME MEASURE: Vestibular function was evaluated by 3 bedside vestibular tests (observation of spontaneous nystagmus, head shaking test, and head thrust test) and by a caloric test. Tests were performed on days 10 and 30 after completion of treatment. Tests were also performed 3, 6, and 12 months from completion of the gentamicin-FTA protocol. The effects of treatment were also assessed in terms of hearing levels, control of vertigo, and disability status. RESULTS: In 22 of the 26 patients, only 1 gentamicin-FTA injection was necessary to obtain 1 or more signs indicating a reduction of the vestibular function in the treated ear. Four patients needed another treatment because of the persistence of their incapacitating symptoms during the follow-up. Four patients needed more than 1 injection to obtain a vestibular hypofunction. None of the patients who received 1 or 2 injections presented hearing loss in direct temporal relationship to the treatment. CONCLUSIONS: A mixture of gentamicin and fibrin glue makes it possible to considerably reduce the number of administrations in patients with intractable unilateral Meniere's disease. Spontaneous nystagmus, post head shaking nystagmus, and a head thrust sign are the clinical signs that indicate onset or progression of unilateral vestibular hypofunction. These signs were obtained with only 1 injection in 81% of patients.

Conclusion. Our data indicate that Meniett therapy is unlikely to be helpful in the long-term treatment of patients with severe, drug-resistant Meniere's disease (MD) in whom injection of intratympanic gentamicin (ITG) or another destructive procedure would otherwise be performed. Objective. To investigate the value of Meniett therapy in patients with drug-resistant MD referred for injection of ITG. Material and methods. Twelve patients referred for ITG treatment were followed during a 2-month period of Meniett therapy. Symptoms, functional level and hearing status were evaluated using a standardized staging system. Disease-specific quality-of-life measures were obtained before and after Meniett therapy. At the end of the study period, patients were followed for a mean of 37 months, thus providing long-term outcome data. Results. In two patients, Meniett treatment was interrupted after 1 month because of persistent severe vertigo. In the remaining 10 subjects, we found a significant decrease in the median number of vertigo spells from 10.0/month (25th-75th percentile 4.0-19.0) prior to treatment to 3.0/month (25th-75th percentile 1.5-4.5) after treatment (p=0.02). There was, however, no improvement in hearing status, tinnitus, functional level or self-perceived dizziness handicap. Long-term (>1 year) follow-up data revealed that only 2 subjects preferred to continue Meniett therapy and that ablative surgery had to be performed in 6/12 study patients.

CONCLUSIONS: Interval treatment with up to three intratympanic gentamicin injections once weekly effectively controlled vertigo while preserving hearing in patients with Meniere's disease and recurrent or resistant vertigo after saccotomy. OBJECTIVES: Recurrent or resistant incapacitating vertigo may occur after endolymphatic sac surgery (saccotomy) in patients with Meniere's disease. In these patients, revision saccotomy, vestibular nerve section or labyrinthectomy are the established treatment options. We advocate a once-weekly application of intratympanic gentamicin (12 mg) as an effective alternative in this group of patients. MATERIAL AND METHODS: Five patients (age range 39-65 years) with definite Meniere's disease according to the 1995 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) criteria and incapacitating vertigo underwent gentamicin treatment after saccotomy. Control of vertigo and hearing preservation were the aims of treatment. The follow-up period ranged from 26 to 59 months. History and pure-tone audiometry were used to assess vertigo control and hearing, respectively. The frequency of vertigo in the 6-month period before gentamicin treatment ranged between 0.5 and four definitive episodes per month. Hearing stage (AAO-HNS criteria) before gentamicin treatment ranged between 2 and 4. Pre- and post-treatment pure-tone hearing thresholds at 0.5, 1, 2 and 3 kHz were compared by means of the Mann-Whitney U-test. RESULTS: Complete vertigo control (class A; AAO-HNS) and hearing preservation at 0.5, 1, 2 and 3 kHz were achieved.

Treatment of Meniere's disease with the low-pressure pulse generator (Meniett device).
Gates GA.
University of Washington, Virginia Merrill Bloedel Hearing Research Center, 1959 NE Pacific Street, Seattle, WA 98195, USA. ggates@u.washington.edu

Until recently, surgery was the only treatment option for people with disabling Meniere's disease that did not respond to adequate medical therapy. A new intermediate level treatment modality, the Meniett device, which applies low-pressure micropulses to the inner ear, has now been shown to be safe and effective. The device is portable and self-administered, requiring a 5-min three-times daily application for an indefinite period. Placement of a tympanostomy tube in the ear drum of the affected ear is necessary. Patient acceptance has been high. Long-term success in control of vertigo is over 80%. Although hearing loss is not improved, Meniett device usage does not adversely affect balance, as do most forms of surgical therapy. Use of the device does not preclude later surgical therapy.

Morales-Luckie E, Cornejo-Suarez A, Zaragoza-Contreras MA, Gonzalez-Perez O.
Department of Otolaryngology, Hospital de Especialidades del Centro Medico Nacional de Occidente, Instituto Mexicano del Seguro Social, Guadalajara, Mexico.

OBJECTIVE: To establish whether the oral administration of moderate doses of prednisone reduces refractory vertigo in Meniere's disease. STUDY DESIGN: Blinded, randomized, controlled trial. SETTING: Tertiary referral center. PATIENTS: Patients with Meniere's disease with limited vertigo control (Class C) and severe disability (Scale 3). INTERVENTIONS: Two groups (n = 8 per group) were treated orally with either diphenidol (25 mg/d) plus acetazolamide (250 mg/48 h) (control group), or the same treatment plus prednisone (0.35 mg/kg) daily for 18 weeks (prednisone group). MAIN OUTCOME MEASURES: The variables evaluated were the frequency and duration of vertigo, tinnitus, aural fullness, and audiographic parameters. The clinical surveillance was performed for 12 months after prednisone withdrawal. RESULTS: The frequency and duration of vertigo episodes were reduced by 50% and 30%, respectively, by prednisone treatment. Prednisone-treated patients manifested a significant reduction in tinnitus. No changes were observed in aural fullness or hearing. No metabolic or infectious disorders were observed. CONCLUSION: Oral prednisone helps to control refractory vertigo in Meniere's disease. These preliminary data suggest that prednisone can be a good noninvasive antivertigo management regimen for these patients.

Intratympanic dexamethasone and hyaluronic acid in patients with low-frequency and Meniere's-associated sudden
sensorineural hearing loss.

Department of Otolaryngology, Head and Neck Surgery, University of Mainz Medical School, Mainz, Germany. selivanova@hno.klinik.uni-mainz.de

BACKGROUND: Steroids are widely used for the treatment of cochleovestibular disorders. Direct steroid application in the middle ear cavity, when combined with a round window membrane permeability-modulating substance, increases the level of the steroid reaching the target cells. We measured hearing in patients with idiopathic isolated low-frequency sensorineural hearing loss and in patients with sudden sensorineural hearing loss and a history of Meniere's disease. Contradictory reports about effectiveness of intratympanic steroid therapy on vertigo control and hearing improvement in patients with Meniere's disease exist in the literature. METHODS: Eighteen patients with isolated low-frequency idiopathic sudden sensorineural hearing loss and 21 patients with sudden sensorineural hearing loss and a history of Meniere's disease were prospectively evaluated. The acute effect of the intratympanic application of dexamethasone with hyaluronic acid on hearing outcome after failure of an initial standard treatment with intravenous steroid and vasoactive substances was assessed. Evaluation was based on standard pure-tone audiometry findings. RESULTS: After intratympanic injection of dexamethasone and hyaluronic acid, 14 of the 18 patients with isolated low-frequency sensorineural hearing loss showed a significant improvement in hearing. After intratympanic therapy, 15 patients with a previous history of Meniere's disease and idiopathic isolated low-frequency sensorineural hearing loss showed an improvement in hearing on pure-tone audiometry, four remained unchanged, and two showed a tendency toward a slight deterioration. CONCLUSION: Intratympanic combined dexamethasone/hyaluronic acid application provides a reliable and safe therapeutic option for improvement of hearing in patients with isolated low-frequency idiopathic sudden sensorineural hearing loss or sensorineural hearing loss resulting from Meniere's disease who have failed intravenous steroid and vasoactive treatments.

Effects of intratympanic injection of latanoprost in Meniere's disease: a randomized, placebo-controlled, double-blind, pilot study.
Rask-Andersen H, Friberg U, Johansson M, Stjernschantz J.
Department of Otosurgery, University Hospital, Uppsala, Sweden. helge.rask-andersen@akademiska.se

OBJECTIVE: To determine the short-term effects of latanoprost, a selective FP prostanoid receptor agonist, in Meniere's disease. STUDY DESIGN AND METHODS: Latanoprost was administered by intratympanic injection once daily for 3 days. Before the first injection (day 1) and on days 5 and 15, hearing and tinnitus were determined. The patients assessed vertigo on a visual analogue scale on days 1-15. The study was randomized, double-blind, and placebo-controlled. RESULTS: Latanoprost reduced vertigo/dysequilibrium around 30% (P < 0.05), and improved speech discrimination around 15% (P < 0.05). Tinnitus loudness deteriorated after injection of placebo (P < 0.01) but not after latanoprost. Side effects were few. CONCLUSION AND SIGNIFICANCE: Latanoprost alleviated vertigo/dysequilibrium and improved hearing. The results indicate that the drug potentially could be useful for treatment of Meniere's disease.

Department of Defense Spatial Orientation Center, Naval Medical Center San Diego, CA 92134, USA. krgottshall@nmcsd.med.navy.mil

OBJECTIVE: To study the role of vestibular rehabilitation is treating patients with Meniere's disease. METHODS: We examined all Meniere's patients presenting to our tertiary care specialized vestibular clinic during a 1-year period. All patients underwent a standardized history and physical examination, a complete auditory-vestibular test battery, and a set of physical therapy tools to measure balance function. RESULTS: A subset of patients suffered from disequilibrium or unsteadiness between attacks. Once the acute fluctuating symptoms of Meniere's were controlled in this group of individuals, all of them underwent vestibular physical therapy and demonstrated significant improvement in balance function on both objective and self-report tests. CONCLUSIONS: Due to the fluctuating nature of the disorder, vestibular physical therapy has had a limited role in the treatment of Meniere's disease. In general, rehabilitation has been used only as a postoperative treatment for the acute vertigo seen after vestibular neurectomy or labyrinthectomy. This is the first report advocating the role of vestibular physical therapy in a group of patients receiving medical therapy of intraear medicines (other that gentamicin).

Durland WF Jr, Pyle GM, Connor NP.
Division of Otolaryngology-Head and Neck Surgery, Department of Surgery, University of Wisconsin, 600 Highland Avenue, Madison, WI 53792, U.S.A.

OBJECTIVES/HYPOTHESIS: Endolymphatic sac decompression is a surgical treatment option for patients with medically intractable Meniere's disease. However, effectiveness is debated because published data show great variability. Outcome-based research studies are useful in incorporating the patient's perspective on the success of treatment. To further assess effectiveness of endolymphatic sac decompression, we performed a prospective study to examine both symptom-specific and general health outcomes. STUDY DESIGN: Prospective, observational outcome study. METHODS: Nineteen patients with endolymphatic sac decompression responded to symptom-specific questionnaires and the Medical Outcomes Short-Form 36 Health Survey (SF-36) before and after surgery. Follow-up ranged from 6 to 58 months with a mean duration of 50 months. RESULTS: Overall measures of physical health were significantly improved following endolymphatic sac decompression (P = .04), whereas overall measures of mental health were unchanged (P = .74). Role Physical and Social Functioning scores were significantly improved following endolymphatic sac decompression (P = .04 and P = .03, respectively). Study patients scored significantly lower (P < .05) than SF-36 normative data in 6 of 10 categories before endolymphatic sac decompression but patient scores were not significantly different from normal scores in all but one category (General Health) following endolymphatic sac decompression. The mean number of vertigo episodes was significantly reduced from an average of 8.3 times per month to an average of 2.6 times per month following endolymphatic sac decompression (P = .006). Ninety-five percent of patients (18 of 19 patients) reported improvement in symptoms (frequency, duration, or intensity) of vertigo and 37% (7 of 19 patients) reported complete resolution of vertigo. CONCLUSION: Endolymphatic sac decompression significantly improved perception of physical health, as well as symptom-specific outcomes, in patients with medically intractable Meniere's disease.

OBJECTIVE: To investigate the efficacy of dexamethasone inner ear perfusion by intratympanic injection in hearing loss, tinnitus, aural fullness, and vertigo in the treatment of unilateral Meniere's disease and compare it with the control group. STUDY DESIGN AND SETTING: A prospective, randomized, double-blind study with 2-year follow-up comparing changes secondary to dexamethasone inner ear perfusion versus placebo consisting of saline solution. PATIENTS: Twenty-two patients having definite Meniere's disease as outlined by the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium. All the patients were older than 18 years of age and were not receiving any other form of treatment with steroids for their Meniere's disease. METHOD: Five consecutive daily intratympanic injections of dexamethasone or placebo to the involved ear. RESULTS: In the dexamethasone group at 2-year follow-up, complete control of vertigo (class A) was achieved in 9 of 11 patients (82%) and substantial control of vertigo (class B) in the remaining 2 patients (18%.) In the control group only 7 of 11 patients (64%) finished the 2-year follow-up because in the other 4 patients (36%) we had to give another treatment for the continuing vertigo and thus they were classified as failure (class F.) From the 7 patients who have finished the follow-up of 2 years in the control group, 4 patients (57%) achieved class A, 2 patients (29%) achieved class C, and 1 patient (14%) class F. CONCLUSIONS: Dexamethasone (4 mg/mL) inner ear perfusion in a group of patients with unilateral Meniere's disease (Shea's stage III) showed 82% of complete control of vertigo over placebo (57%). There was also a subjective improvement in tinnitus (48%), hearing loss (35%), and aural fullness (48%) in the dexamethasone group compared with 20%, 10%, and 20% respectively in the control group.

Long-term effects of the Meniett device in Meniere's disease: the Western Australian experience.
Rajan GP, Din S, Atlas MD.
Lions Ear and Hearing Institute, Sir Charles Gairdner Hospital, University of Western Australia, Australia. guneshrajan@hotmail.com

OBJECTIVES: Transtympanic pressure has been shown to influence endolymphatic hydrops. As endolymphatic hydrops plays a key role in Meniere's disease, a few studies, undertaken by the inventors, manufacturers and associates of the Meniett device, have demonstrated positive short-term effects of transtympanic pressure treatment via the Meniett device in medically intractable Meniere's disease. The aim of our study was to independently investigate the long-term efficacy and safety of transtympanic pressure treatment in the management of recalcitrant vertigo in Meniere's disease. DESIGN: Cross-sectional case study. SETTING: Tertiary referral centre. PARTICIPANTS: Eighteen patients with Meniere's disease, suffering from medically intractable symptoms. All patients in the study had Meniere's disease according to the criteria of the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery.Main outcome measurements: Outcome and severity of symptoms were assessed, using the six-point functional scale and the vertigo visual analogue scale (VAS), as recommended by the Committee on Hearing and Equilibrium of the American Academy of Otolaryngology, Head & Neck Surgery. Changes of pure tone average thresholds and vestibular calorics before and during treatment with the Meniett device were recorded. The mean follow-up time was 18 months. RESULTS: Twelve out of 18 patients showed significant improvement in the functional score and in the VAS. Five patients displayed an audiometric improvement, out of which three patients showed a pertaining significant hearing gain of more than 10 dB; the remainder had stable hearing levels. Of six patients without any improvement, four had previous invasive surgery for their Meniere's disease and two had previous vestibular ablation with gentamicin. No changes in vestibular function were noted. There were no complications during the treatment with the Meniett device. CONCLUSION: According to this independent study, the Meniett device seems to be a minimally invasive, non-destructive treatment tool, which can reduce vertigo and associated functional handicap in Meniere's disease. These effects are maintained up to 18 months after treatment so far. Previous surgical or chemical vestibular ablation procedures may adversely influence the effect of the Meniett device.

Wilson Ear Clinic, 911 NW 18th Avenue, Portland, OR 97209, USA. galbey@yahoo.com

OBJECTIVE: To determine the practices of the American Neurotology Society (ANS) membership in the evaluation and treatment of the Meniere's patient. STUDY DESIGN: Prospective. INTERVENTION: Questionnaire. MAIN OUTCOME MEASURE: Respondents' response to questions pertaining to the diagnostic and therapeutic practices in the management of Meniere's disease. RESULTS: Three hundred members of ANS were mailed a 15-item questionnaire. Two hundred three responded, for a 67.7% response rate. For the diagnosis of Meniere's disease, 1 in 3 practitioners relied solely on history, physical exam, and audiometry, whereas 2 in 3 relied in part on adjunctive tests, such as electrocochleography (ECOG) and electronystagmography (ENG). Two in 3 practitioners pursued retrocochlear studies on initial evaluation, with the overwhelming majority using MRI. In treating Meniere's disease, conservative medical management was preferred. For medically recalcitrant Meniere's disease, endolymphatic sac surgery (ESS) was the most commonly employed initial intervention (50%), followed by transtympanic gentamicin (38%). Currently, <10% routinely recommend the Meniett device. Eighty-three percent include ESS as a therapeutic option for medically recalcitrant Meniere's disease. The vast majority continue to perform surgical labyrinthectomies and vestibular nerve sections for Meniere's disease. CONCLUSIONS: Meniere's disease continues to pose a difficult diagnostic and therapeutic problem, resulting in heterogeneous approaches to both evaluation and treatment. Despite the 1995 American Academy of Otolaryngology guidelines in the diagnosis of Meniere's disease, most clinicians rely in part on ENG or ECOG in diagnosing Meniere's disease. Furthermore, despite the passing of 20 years since the publications claiming a purely placebo effect, ESS is the most commonly employed initial surgical treatment for Meniere's disease.

Vestibular function at the end of intratympanic gentamicin treatment of patients with Meniere's disease.
Perez N, Rama-Lopez J.
Department of Otolaryngology, University Hospital and Medical School, University of Navarra, Spain. nperezfer@unav.es

The aim of this study is to analyze the effects of intratympanic gentamicin injections on vestibular function in 33 patients with unilateral Meniere's Disease (according to AAO-HNS guidelines 1995) that had been unresponsive to medical therapy for at least one year. In such patients, the results of bedside examination of vestibular function vestibular examination is compared to those from laboratory tests. Intratympanic gentamicin injections (27 mg/ml) were performed at weekly intervals until symptoms or signs of vestibular hypofunction developed in the treated ear. Vestibular function was evaluated in two different rotatory chair tests. The parameters that were specifically considered were the time constant of the vestibulo-ocular reflex (VOR) after impulse rotation with a peak chair velocity of 100 degrees s(-1), and the phase and gain of the VOR after the sinusoidal harmonic acceleration (SHA) test with a peak chair velocity of 50 degrees s(-1). After treatment, both the time constant of the VOR after rotation towards the treated side and the gain in the SHA test were significantly reduced. These reductions were in accordance with the number of additional signs observed upon bedside examination at the end of the treatment. The changes observed in the VOR correlate well with the results of bedside examination of vestibular function, which in turn reflects the damage induced by intratympanic gentamicin injection.

Treatment of vertigo.
Swartz R, Longwell P.
Department of Family and Preventive Medicine, University of California, San Diego, School of Medicine, La Jolla, California, USA. swartz.john2@scrippshealth.org

Vertigo is the illusion of motion, usually rotational motion. As patients age, vertigo becomes an increasingly common presenting complaint. The most common causes of this condition are benign paroxysmal positional vertigo, acute vestibular neuronitis or labyrinthitis, Meniere's disease, migraine, and anxiety disorders. Less common causes include vertebrobasilar ischemia and retrocochlear tumors. The distinction between peripheral and central vertigo usually can be made clinically and guides management decisions. Most patients with vertigo do not require extensive diagnostic testing and can be treated in the primary care setting. Benign paroxysmal positional vertigo usually improves with a canalith repositioning procedure. Acute vestibular neuronitis or labyrinthitis improves with initial stabilizing measures and a vestibular suppressant medication, followed by vestibular rehabilitation exercises. Meniere's disease often responds to the combination of a low-salt diet and diuretics. Vertiginous migraine headaches generally improve with dietary changes, a tricyclic antidepressant, and a beta blocker or calcium channel blocker. Vertigo associated with anxiety usually responds to a selective serotonin reuptake inhibitor.

Perez R, Ducati A, Garbossa D, Benech F, Fontanella MM, Canale A, Albera R.
Department of Neuroscience, Neurosurgery Section, University of Torino, Italy.

Background. Vestibular nerve section is considered to be the most effective surgical procedure to control intractable symptoms secondary to Meniere's disease (MD). This study was developed to analyze the adequacy of retrosigmoid vestibular neurectomy in terms of vertigo control, hearing preservation and clinical complications of this procedure.Methods. A retrospective review was carried out on 14 patients affected by definite unilateral MD who underwent vestibular neurectomy via the retrosigmoid approach.Findings. One patient was lost from follow-up; another one had only a short postoperative observation. At follow-up performed on 12 cases, no patients reported any crisis of acute vertigo. Four patients were free from any vestibular symptoms, while 8 reported some slight gait disturbances. Hearing function was preserved in 10 patients and improved in 2. 1 year postoperative vestibular function was absent at the side operated on and unchanged on the other side in all the cases.Conclusions. Vestibular neurectomy via the retrosigmoid approach can be considered a safe and effective procedure in relieving medically refractory vertigo in Meniere's disease, while preserving hearing.

Surgical management of Meniere's disease in the era of gentamicin.
Kaylie DM, Jackson CG, Gardner EK.
Otology Group, Nashville, TN, USA. dkaylie@hotmail.com

OBJECTIVE: For many years, surgery was the mainstay of therapy for medically refractory patients, but recently, transtympanic gentamicin perfusion has attracted increasing interest and is a method frequently used for treating Meniere's disease. Many otologists question the relevance of surgical treatments, and traditional options are rarely discussed or offered to patients. The purpose of this study is to describe results of labyrinthectomy, vestibular nerve section, and endolymphatic mastoid shunt surgery for patients with Meniere's disease and to compare them with published results for gentamicin perfusion. STUDY DESIGN AND SETTING: Retrospective chart review. Two hundred twenty-nine patients underwent surgery for management of Meniere's disease between January 1, 1995 and December 31, 2001. One hundred eighty-nine patients' charts had sufficient data for review. Thirty-two patients had translabyrinthine labyrinthectomies, 83 underwent suboccipital vestibular nerve sections, and 74 elected for an endolymphatic mastoid shunt. Hearing results, dizziness classification, and functional level score were determined from patient charts and telephone conversations. All results were in accordance with the guidelines of the AAO-HNS Committee on Hearing and Equilibrium for evaluation of Meniere's disease therapy. RESULTS: Audiologic results, functional level score, and dizziness classification are reported for the preoperative period and for the 18- to 24-month postoperative period for all surgical patients. These data are also reported individually for each of the 3 surgical procedures. Early postoperative data and most recent follow-up data are presented if available. CONCLUSIONS: Surgical management of Meniere's disease is a safe and viable option for patients with medically refractory disease. EBM rating: C.

Surgical treatment of Meniere's disease.
Van de Heyning PH, Wuyts F, Boudewyns A.
University Department of Otorhinolaryngology, Head and Neck Surgery, Antwerp University Hospital, Antwerp, Belgium. Paul.van.de.heyning@uza.be

PURPOSE OF REVIEW: This review comprises new insights from and discusses the impact of recent medical publications on the surgical treatment of Meniere's disease. RECENT FINDINGS: Refining surgical indications through recognition of clinical conditions with similar symptoms and through a more precise estimation of the degree of disability will improve the process of decision making for surgery. Further high-level evidence-based medical data supporting the effectiveness of intratympanic gentamycin has become available. Physiopathological progress, based on animal experiments, towards surgically applied intracochlear drug delivery is addressed. SUMMARY: Studies using level 1 or 2 evidence-based medicine must be conducted to enable better decision making, such as in the application of intratympanic gentamycin or micropressure Meniett therapy at an earlier stage of Meniere's disease. If the results of such studies are conclusive for surgery, this will lead to a shorter duration of discomfort for patients before being offered the possibility of surgery.

Pharmacology of vertigo/nystagmus/oscillopsia.
Straube A.
Department of Neurology, University of Munich, Munich, Germany. astraube@brain.nefo.med.uni-muenchen.de

PURPOSE OF REVIEW: To describe recent developments in the pharmacological treatment of vertigo and nystagmus while focusing on vestibular neuritis, Meniere's disease, downbeat nystagmus, periodic alternating nystagmus, acquired pendular nystagmus, and superior oblique myokymia. RECENT FINDINGS: In the last 2 years several studies have been published on possible pharmacological treatment options for nystagmus and oscillopsia. In the treatment of vestibular neuritis two studies showed that cortisone treatment was effective for restoring labyrinthine function. This benefit seems more likely if treatment is started within the first 2 days of onset. For recurrent vertigo attacks due to Meniere's disease, the titration technique with daily or weekly doses of intratympanic gentamicin until onset of vestibular symptoms, change in vertigo or hearing loss rated best for complete vertigo control. A new pharmacological treatment option for downbeat nystagmus is the administration of potassium channel blockers (e.g. 4-aminopyridine). They are thought to reinforce the inhibitory action of cerebellar Purkinje cells. Several case reports have proven the beneficial effect of baclofen on periodic alternating nystagmus, of gabapentin and memantine on acquired pendular nystagmus, and of carbamazepine and gabapentin on superior oblique myokymia. SUMMARY: There have been several new developments in the treatment of nystagmus and vertigo over the last 2 years. These include potassium channel blockers for the treatment of downbeat nystagmus, early cortisone treatment to improve recovery of the labyrinth function in vestibular neuritis, and intratympanic gentamicin treatment for Meniere's disease. Other pharmacological treatment options are baclofen for periodic alternating nystagmus, gabapentin and memantine for acquired pendular nystagmus, and carbamazepine for superior oblique myokymia.

Department of Otolaryngology/Head & Neck Surgery, Gentofte University Hospital, Hellerup, Denmark. jetho@gentoftehosp.kbhamt.dk

OBJECTIVES: To evaluate the efficacy of a new device, the Meniett, in the treatment of Meniere's disease. The device delivers pressure pulses to the middle ear through a ventilating tube in the tympanic membrane at a frequency of 6 Hz for 0.6 second. After rising to a pressure level of 1.2 kPa, the pressure oscillates between 0.4 and 1.2 kPa. It is believed that the pressure changes are conveyed to the inner ear, inducing a transport of fluids via the pressure outlets and thus reducing the endolymphatic hydrops. STUDY DESIGN: A clinical, randomized, multicenter, double-blind, placebo-controlled study. A total of 40 patients were included that had active Meniere's disease according to American Academy of Otolaryngology-Head and Neck Surgery criteria, aged between 20 and 65 years, with a history of at least eight attacks during the past year. After insertion of the ventilation tube, the patients should have had attacks of vertigo for 2 months before entering the study. OUTCOME MEASURES: Primary study endpoints were change in frequency of vertigo, change of functionality profile, and change in patient perception of vertigo (visual analogue scale); secondary endpoints were perception of tinnitus, aural pressure, and hearing, as well as an audiologic evaluation of hearing before and after the treatment period. RESULTS: The functionality level improved statistically significantly in the active group compared with the placebo group (p=0.0014), as did the visual analogue scale evaluation of vertigo (p=0.005). There was a trend toward a reduction of the frequency of vertiginous attacks that was not significant (p=0.090). With regard to the secondary endpoints, there was no statistical difference between active and placebo groups. CONCLUSION: Local overpressure treatment is a novel treatment that is noninvasive, nondestructive, and safe. It significantly reduces vestibular symptoms in patients with Meniere's disease. The Meniett was cleared by the Food and Drug Administration in 2000.

Randomized double-blinded, placebo-controlled clinical trial of famciclovir for reduction of Meniere's disease symptoms.
Derebery MJ, Fisher LM, Iqbal Z.

Objective To conduct a clinical trial of famciclovir for symptom control in Meniere's disease. Study design and setting Randomized, double-blinded placebo-controlled clinical trial in a tertiary referral center, with 12 subjects in the active treatment arm and 11 subjects in the placebo arm. Results There were no serious adverse events. Twenty-five percent of the famciclovir group and 18% of the placebo group showed a reduction in number of vertigo spells, the primary efficacy endpoint. This difference was not statistically significant. All subjects improved in dizziness and health-related quality of life. There was a trend for the famciclovir arm to have less fluctuation in hearing relative to the placebo arm. Conclusion No dramatic effects of famciclovir were found on vertigo or dizziness. Some promising effects on reduction of the fluctuation in hearing were observed. Significance Famciclovir may suppress the fluctuation of hearing in Meniere's disease, but had a minimal effect on vertigo or dizziness symptoms in this study. The probable multifactorial etiology in Meniere's disease requires that further studies be conducted to determine the effects of antiviral medications. EBM rating: A.

Intratympanic Gentamicin for Meniere's Disease: a Meta-Analysis.
Cohen-Kerem R, Kisilevsky V, Einarson TR, Kozer E, Koren G, Rutka JA.
>From the Department of Otolaryngology-Head and Neck Surgery (r.c.-k.) and the Division of Clinical Pharmacology and Toxicology (r.c.-k., e.k., g.k.), Hospital for Sick Children, Toronto, Canada; the Department of Otolaryngology-Head and Neck Surgery (v.k., j.a.r.), University Health Network, Toronto General Hospital, Toronto, Canada; and the Leslie Dan Faculty of Pharmacy and University of Toronto (t.r.e.), Toronto, Canada.

OBJECTIVES:: To systematically review the published experience on intratympanic gentamicin treatment for intractable Meniere's disease. STUDY DESIGN:: Meta-analysis using a random effect model. METHODS:: A comprehensive literature search was performed for articles using intratympanic gentamicin as a sole treatment modality with reporting of results according to the American Academy of Otolaryngology Head and Neck Surgery (AAO-HNS) guidelines for Meniere's disease. Two reviewers independently assessed trial quality and extracted data. RESULTS:: Fifteen trials with 627 patients met the inclusion criteria. All trials reported "before-after" outcome measures, using patients as their own controls. No double-blind or blinded prospective control trials were identified. Complete (class A) vertigo control was achieved in 74.7% (confidence interval [CI]95% 67.8-81.5%) of patients, and complete or substantial (class B) control was achieved in 92.7% (CI95% 89.5-96.0%). The success rate was not affected by gentamicin treatment regimen (fixed vs. titration). Hearing level and word recognition were not adversely affected, regardless of gentamicin treatment regimen. Analysis of functional level was not performed because of lack of data in the selected articles. CONCLUSIONS:: Intratympanic gentamicin treatment for intractable Meniere's disease appears to be effective in the relief of vertigo. Cochleotoxicity and ototoxicity is unlikely to be a major side effect. However, the level of evidence reflected from the eligible articles is insufficient, especially because of relatively poor study design. Therefore, it is prudent that patients eligible for this type of treatment should be selected carefully and titrated with low-dose gentamicin. Further investigation with this treatment modality with control subjects is warranted.

OBJECTIVE:: To review published literature regarding the use of intratympanic steroids in the treatment of Meniere's disease and sudden sensorineural hearing loss and to make recommendations regarding their use based on the literature review. DATA SOURCES:: Literature review from 1996 to 2003, PubMed, Medline Plus, and Web of Science. STUDY SELECTION:: Retrospective case series and uncontrolled prospective cohort studies were the only types of studies available for review. CONCLUSION:: On the basis of the available literature, a weak recommendation is made to use intratympanic steroid treatment of sudden hearing loss if oral steroid therapy fails or is con-traindicated. The available studies regarding intratympanic steroid treatment of Meniere's disease and tinnitus are inadequate to answer the question of the efficacy of this treatment for these conditions. Higher quality studies are needed.

Audiological and Vestibular Laboratory, E. Warminski's City Hospital, Poland. osinskak1@wp.pl

The aim of this study was to evaluate the usefulness of ozone and pressure-pulse therapies in treating Meniere's disease. Using objective otoacoustic emissions and short-increment sensitivity index (SISI) tests together with subjective anamnesis, we tested 15 patients (8 men, 7 women) who had suffered from Meniere's disease for 1-3 years and had permanent sensorineural hypoacusis; we compared results before and after treatment. We performed ozone therapy and pressure-pulse treatments simultaneously for one 10-minute session each day for 10 consecutive days. After treatment, both otoacoustic-spontaneous and transiently evoked emissions and SISI test results exhibited no statistically significant changes. However, the subjective state of the patients was clearly improved. The frequency, severity of attacks, and tinnitus decreased. The mechanism of such an improvement is discussed.

Department of Otorhinolaryngology, the Second Hospital of Xiangya Medical College, Central South University, Changsha, 410011, China.

OBJECTIVE: To investigate the efficacy of intratympanic dexamethasone injections (IDI) for 15 patients with intractable Meniere's disease (MD). METHOD: Dexamethasone (2.5 mg/0.5 ml) was injected into the middle ear and followed by a second injection 15 minutes later. The injection was repeated the next day and weekly for 3 weeks. Total dose of dexamethason was 17.5 mg. RESULT: The 15 patients were followed up for 18 months (average). Complete relief of vertigo was maintained in 10 cases, improved in 2 case, injection wos repeatad 3 patients with recurrent vertigo resulted in control of vertigo. Tinnitus disappeared in 5 cases, reduced in 5 cases, unchanged in 5 cases. Hearing was improved in 10 cases, unchanged in 5 cases. CONCLUSION: IDI is effective for intractable MD. The benefits of IDI are avoidance of systemic use of steroids, lower cost, easy application. IDI can be used as an initial surgical treatment for persistent vertigo in MD and indicated for bilateral MD.

Long-term results of gentamicin inner ear perfusion in Meniere's disease.
Suryanarayanan R, Cook JA.
Department of Otolaryngology and Leicester Balance Centre, Leicester Royal Infirmary, Leicester, UK.

Chemical perfusion of the inner ear is an increasingly popular treatment for Meniere's disease. The authors report on the long-term results of 22 patients treated with gentamicin delivered via a round window micro-catheter. Patients with Meniere's disease underwent continuous, low dose (10 mg/ml) gentamicin infusion at 5 microlitre per hour for 10 days, through a micro-catheter placed into the round window niche. Vertigo was controlled in 95 per cent, whilst preserving hearing in 77 per cent. Hearing improved in three patients. Three patients with pre-operative serviceable hearing (PTA < 50 db) demonstrated reduced hearing; two patients with pre-operative non-serviceable hearing developed a dead ear. Tinnitus and aural fullness remained unchanged or improved in 86 per cent and 68 per cent respectively. Long-term vertigo control can be achieved using low dose gentamicin, whilst preserving hearing and vestibular function in the majority of patients. This procedure appears to stabilize the vestibular function, enhancing the chance of effective vestibular rehabilitation.

Division of Otolaryngology, Head and Neck Surgery, Department of Surgery, School of Medicine, University of California at San Diego, USA.

OBJECTIVE: This study compared the effectiveness of five different techniques of intratympanic gentamicin administration for Meniere's disease. DATA SOURCES: A MEDLINE search of the English language literature from 1978 to 2002 was performed using the key words "intratympanic," "gentamicin," "therapy," "Meniere's," and "disease." STUDY SELECTION: Inclusion criteria to select articles for meta-analysis were clear description of gentamicin delivery technique, clearly reported vertigo control results, and report of hearing loss posttreatment. Seven studies (n = 218) describing the multiple daily dosing technique (delivery three times per day for >or=4 d), two studies (n = 84) describing the weekly dosing technique (weekly injections for four total doses), eight studies (n = 253) of the low-dose technique (one to two injections with retreatment for recurrent vertigo), four studies (n =156) of continuous microcatheter delivery, and six studies (n =269) of the titration technique (daily or weekly doses until onset of vestibular symptoms, change in vertigo, or hearing loss) were entered into the model. DATA EXTRACTION: Vertigo control results were stratified into complete, substantial, or poor control. Hearing results were separated by profound, partial, or no hearing loss. Individuals undergoing caloric testing were separated by degree of vestibular ablation (complete versus partial) and analyzed for vertigo control (n = 301) and hearing loss (n = 333) after treatment. DATA SYNTHESIS: Comparisons between the rates of complete vertigo control, effective vertigo control (complete plus substantial control), overall hearing loss (partial plus profound), and profound hearing loss by delivery method were based on a parametric empirical Bayes analysis using binomial generalized linear models and backward variable selection (joining). Relative risk for vertigo control and hearing loss by partial or complete ablation was examined study by study using residual maximum likelihood to carry out a parametric empirical Bayes analysis. CONCLUSION: The titration method of gentamicin delivery demonstrated significantly better complete (81.7%, p = 0.001) and effective (96.3%, p < 0.05) vertigo control compared with other methods. The low-dose method of delivery demonstrated significantly worse complete vertigo control (66.7%, p < 0.001) and trends toward worse effective vertigo control (86.8%, p = 0.05) compared with other methods. The weekly method of delivery trends toward less overall hearing loss (13.1%, p = 0.08), and the multiple daily method demonstrated significantly more overall hearing loss (34.7%, p < 0.01) compared with other groups. No significant difference in profound hearing loss was found between groups. Degree of vestibular ablation after gentamicin therapy is not significantly correlated with the resulting vertigo control or hearing loss status.

We conducted a retrospective outcomes review of the charts of 22 patients with Meniere's disease who were treated with intratympanic perfusion of methylprednisolone and/or dexamethasone. Outcomes were determined by subjective assessment of vertigo control and by objective changes in audiometric pure-tone average (PTA) and speech discrimination score (SDS). These evaluations were made at the first postperfusion visit (short term) and at least 12 months later (long term). In the short term, 12 patients (54.5%) achieved vertigo control, 4 patients (18.2%) demonstrated a greater than 10-dB improvement in PTA, and 1 patient (4.5%) experienced an increase in SDS of at least 15%. In the long term, the corresponding numbers of patients were 4 (18.2%), 2 (9.1%), and 1 (4.5%). The level of hearing ultimately deteriorated in 9 patients (40.9%). These findings suggest that intratympanic steroid perfusion does not result in any long-term alleviation of vertigo or hearing loss. However, the short-term alleviation of vertigo seen in approximately half of these patients suggests that this treatment may be useful for the temporary relief of symptoms of Meniere's disease.

Department of Otolaryngology-Head and Neck Surgery, University of Washington School of Medicine, Seattle, USA. ggates@u.washington.edu

OBJECTIVE: To evaluate the efficacy of a portable low-intensity alternating pressure generator, the Meniett device, in controlling the symptoms of Meniere's disease. DESIGN: A randomized, placebo-controlled, double-blind, multicenter clinical trial of 4 months' duration. SETTING: Four study sites: 3 academic medical centers and 1 private practice. PATIENTS: Sixty-seven people aged 33 to 71 years with established, active, unilateral cochleovestibular Meniere's disease randomly assigned to a treatment or control group. Five cases were excluded (2 dropouts, 3 protocol violations), leaving 62 evaluable cases. INTERVENTION: The Meniett device was self-administered 3 times daily. The placebo Meniett device was identical but exerted no pressure. All participants had a tympanostomy tube inserted in the affected ear. MAIN OUTCOME MEASURES: Participants rated vertigo and activity each day on a symptom report card. Hearing tests, electrocochleography, and questionnaires were completed at baseline, 2 months, and 4 months. RESULTS: The treatment group experienced significantly less severe vertigo, fewer days with definitive vertigo, and fewer days lost from work (sick days) during the follow-up period than did the control group. Hearing and electrocochleographic results did not differ between the groups. Outcomes did not differ by age, gender, laterality, or duration of symptoms. Outcomes were affected by vestibular loss and baseline level of vertigo. The tympanostomy tube had no short-term effect on vertigo symptoms. There were no complications from using the Meniett device. CONCLUSION: The Meniett device is a minimally invasive, safe, and efficacious intermediate treatment for people with substantial vertigo uncontrolled by medical therapy.

If a clinician seeks to allow patients with vertigo to return to work as soon as possible, it is very important to determine the appearance of vestibular symptoms during convalescence just after treatment, as well as the long-term results. Apprehensive patients with vertigo may undergo severe psychological torment if treatment requires long-term rest in bed before they can return to daily life. In this paper, we observed postoperative vestibular symptoms (subjective sensation and objective nystagmus) in 50 patients with intractable Meniere's disease, including cases from our previous preliminary report, during the period of convalescence just after endolymphatic sac drainage and steroid instillation surgery (EDSS). All symptoms were eliminated within 8 days after EDSS. There was no significant difference in the duration of any vestibular symptoms between bilateral (n = 8) and unilateral cases (n = 42). This result indicates that EDSS could be as safe a treatment for bilateral Meniere's disease as for unilateral disease. In unilateral cases with intact semicircular canal function (n = 17), postoperative evoked vestibular sensation, positional, and positioning (Dix-Hallpike) nystagmus disappeared significantly earlier than in those with canal paresis (n = 25). This result indicates that EDSS could keep the vestibular peripheral function of patients with unilateral Meniere's disease with intact canals quite stable after surgery. Therefore, EDSS could be recommended as an initial, less-invasive surgical treatment for intractable Meniere's disease, especially in unilateral cases with intact canals and in bilateral cases.

*Kaiser Permanente Medical Center, Union City, California, and daggerMichigan Ear Institute, Farmington Hills, Michigan, U.S.A.

OBJECTIVE:: To develop a disease-specific instrument to measure the quality of life in patients with Meniere's disease and to assess quality-of-life outcomes after endolymphatic sac decompression. STUDY DESIGN:: Retrospective survey. PATIENTS:: Patients with Meniere's disease who underwent endolymphatic sac decompression from June 1996 to June 2001, after failing a course of medical management. Two hundred fifteen potential subjects were identified; completed questionnaires were returned by 159 patients. MAIN OUTCOME MEASURES:: The Meniere's Disease Outcomes Questionnaire was developed, and consists of questions in three domains that determine quality of life: physical, emotional, and social well-being. The Meniere's Disease Outcomes Questionnaire consisted of 18 multiple-choice questions that were paired for pre- and postoperative conditions, and one global quality-of-life question. The preoperative quality-of-life score (total score for preoperative items) was compared with the postoperative quality-of-life score. The main outcomes measure was the change in quality-of-life score. RESULTS:: Overall, the mean change in quality-of-life score was +25.6 points (range, -34 to 83) (p < 0.001). The change in Meniere's Disease Outcomes Questionnaire quality-of-life score was highly correlated with the change in the global question score (p < 0.01). Quality of life was improved in 87% of respondents, unchanged in 3% of patients, and poorer in 9% of patients after endolymphatic sac decompression. CONCLUSIONS:: The Meniere's Disease Outcomes Questionnaire is a new disease-specific quality-of-life tool that is a valid measure of quality of life in patients with Meniere's disease, and is responsive to measuring change in quality of life after treatment. Significant improvement in quality of life was reported by 87% of patients after endolymphatic sac decompression.

OBJECTIVE: To establish the efficacy of intratympanic gentamicin treatment in patients with unilateral Meniere's disease. MATERIAL AND METHODS: This was a prospective, double-blind, randomized clinical trial of intratympanic gentamicin versus intratympanic buffer solution (placebo) in patients with established active Meniere's disease in the affected ear. Outcome measures included the number of vertiginous spells, degree of sensorineural hearing loss, labyrinthine function and labyrinthine asymmetry. RESULTS: Topical gentamicin provided a significant reduction in the number of vertiginous spells, although a "placebo effect" was also observed. Sensorineural hearing loss did not occur in the gentamicin group, although some deterioration occurred in the placebo group. CONCLUSIONS: Intratympanic gentamicin is a safe and efficient treatment for the vertiginous spells associated with Meniere's disease. When applied early in the course of the disease, it may prevent some of the sensorineural hearing deterioration associated with it.

The treatment of acute vertigo.
Cesarani A, Alpini D, Monti B, Raponi G.
ENT Department, University of Milan, Milan, Italy.

Vertigo and dizziness are very common symptoms in the general population. The aim of this paper is to describe the physical and pharmacological treatment of symptoms characterized by sudden onset of rotatory vertigo. Acute vertigo can be subdivided into two main groups: (1) spontaneous vertigo and (2) provoked vertigo, usually by postural changes, generally called paroxysmal positional vertigo (PPV). Sudden onset of acute vertigo is usually due to acute spontaneous unilateral vestibular failure. It can be also fluctuant as, e.g., in recurrent attacks of Meniere's disease. Pharmacotherapy of acute spontaneous vertigo includes Levo-sulpiride i.v., 50 mg in 250 physiologic solution, once or twice a day, methoclopramide i.m., 10 mg once or twice a day, or triethilperazine rectally, once or twice a day, to reduce neurovegetative symptoms; diazepam i.m., 10 mg once or twice a day, to decrease internuclear inhibition, sulfate magnesium i.v., two ampoules in 500 cc physiological solution, twice a day, or piracetam i.v., one ampoule in 500 cc physiological solution, twice a day, to decrease vestibular damage. At the onset of the acute symptoms, patients must lie on their healthy side with the head and trunk raised 20 degrees. The room must be quiet but not darkened. If the patient is able to swallow without vomiting, it is important to reduce nystagmus and stabilize the visual field with gabapentine, per os, 300 mg twice or three times a day. The first step of the physical therapy of acute vertigo is vestibular electrical stimulation, that is to say, a superficial paravertebral electrical stimulation of neck muscles, aimed to reduce antigravitary failure and to increase proprioceptive cervical sensory substitution. PPV is a common complaint and represents one of the most common entities in peripheral vestibular pathology. While the clinical picture is well known and widely described, the etiopathogenesis of PPV is still a matter of debate. Despite the different interpretation of PPV etiopathogenesis, the maneuvers described by Semont, Epley, or Lempert and their modifications are undoubtedly effective. For this reason the first therapeutic approach in acute provoked vertigo must be by means of one of these kinds of treatments.

PURPOSE OF REVIEW: Meniere's disease is characterized by spontaneous attacks of vertigo, fluctuating sensorineural hearing loss, aural fullness, and tinnitus. The pathologic process involves distortion of the membranous labyrinth with the formation of endolymphatic hydrops. This review describes the pathogenesis and etiology as well as the diagnosis and treatment of Meniere's disease. RECENT FINDINGS: Initial management of Meniere's disease can involve a low-salt diet and a diuretic. Treatment with intratympanic injection of gentamicin can be beneficial when vertigo persists despite optimal medical management. Recent studies have shown that gentamicin reduces vestibular function in the treated ear, although complete ablation of this vestibular function is not typically required in order to achieve control of vertigo. SUMMARY: Vertigo is often the most debilitating symptom associated with Meniere's disease. Many treatment options exist for the management of vertigo. Intratympanic injection of gentamicin (low dose) can be used in patients for whom vertigo has not been controlled by medical measures. Ongoing research is providing a greater understanding of the effects of gentamicin on vestibular function and of the mechanisms through which gentamicin leads to control of vertigo.

Vestibular nerve section versus intratympanic gentamicin for Meniere's disease.
Hillman TA, Chen DA, Arriaga MA.
Pittsburgh Ear Associates, 429 East North Avenue, Suite 422, Pittsburgh, PA, USA.

OBJECTIVES/HYPOTHESIS:Vestibular nerve section and transtympanic gentamicin administration are procedures with proven efficacy in the treatment of vertigo associated with Meniere's disease refractory to medical management. Hearing loss is a known complication of each of these procedures; however, there has not been a report of hearing results of both treatments from a single institution. STUDY DESIGN: Retrospective review. METHODS: Review was made of 25 patients undergoing gentamicin injection and 39 patients undergoing vestibular nerve section for Meniere's disease. Rate of vertigo control and pretreatment and post-treatment pure-tone average values and speech discrimination scores were reported. RESULTS: The mean preoperative pure-tone average for patients having vestibular nerve section was 47.2 dB, with a speech discrimination score of 75.4%. In these patients, the postoperative pure-tone average was 49.1 dB and the speech discrimination score was 75%. Patients undergoing gentamicin injection had a mean pretreatment pure-tone average of 55.9 dB and a speech discrimination score of 62%. The post-treatment pure-tone average and speech discrimination score for the gentamicin group were 68.8 dB and 49.3%, respectively. Five of 25 patients (20%) in the gentamicin treatment group and 1 of 39 (3%) in the vestibular nerve section treatment group had an increase in bone-conduction threshold greater than 30 dB. The amount of postprocedure hearing loss was significantly greater in the gentamicin treatment group (P =.006). Control of vertigo was good to excellent in 95% of the patients treated with vestibular nerve section and in 80% of the patients treated with gentamicin. CONCLUSION: Although vestibular nerve section and transtympanic gentamicin are both acceptable treatment options for vertigo associated with Meniere's disease, gentamicin causes a higher level of hearing loss related to treatment and vestibular nerve section has higher vertigo control rates.

BACKGROUND: Intratympanic gentamicin is an accepted mode of treatment for patients with Meniere's disease who suffer from recurrent vertigo attacks in spite of conservative medical treatment. Recently, it gained popularity as the primary treatment for intractable Meniere's disease, prior to surgical procedures. However, administration methods and treatment protocols still differ from one medical center to another. OBJECTIVES: We aimed to present outcomes of gentamicin treatment for vertigo attacks and functional capacity, based on our experience with 23 patients over 3 years and review the literature on the subject. METHODS: Three specially prepared gentamicin injections, were administered once a month, according to the state of vertigo attacks, functional capacity, and hearing status. Clinical observation, frequent hearing examinations and caloric tests were used for follow-up. RESULTS: Following treatment, 20 (87%) patients no longer experienced vertigo attacks, while 16 of them (69.6%) reported full functional recovery. Two patients (8.7%) did not respond to treatment, and therefore, underwent surgical procedures. One patient (4.4%) did not complete therapy. Post treatment caloric tests showed significant deterioration (P < 0.02). Severe vestibular weakness (51-100%) was found in the treated ear in 11 of the 14 patients with unilateral disease (78.6%). The mean change in hearing examination was non-significant. However, two of the 21 patients suffered a change from moderate to severe hearing loss to complete deafness (9.5%). There was no case of post treatment infection or permanent tympanic perforation. CONCLUSIONS: Intratympanic gentamicin injection is a simple and safe procedure for intractable Meniere's patients, with a high success rate and low risk for hearing deterioration. It is recommended for patients with continuous functional disability prior to surgical treatment.

Long-term results after interval therapy with intratympanic gentamicin for Meniere's disease.
Lange G, Maurer J, Mann W.
Department of Otorhinolaryngology, University of Mainz, Medical School, Germany.

OBJECTIVES: The new single-shot and interval treatment for Meniere's disease with gentamicin was designed to avoid cochlear damage during treatment with gentamicin. METHODS: To date, 90 patients were treated with the single-shot or interval gentamicin therapy. Fifty-seven cases of Meniere's disease were followed up prospectively between 2 and 4 years. During one treatment series, a maximum of three intratympanic gentamicin injections within 15 days were applied, each consisting of 0.3 mL (12 mg) of gentamicin (days 1, 8, and 15). Thirty of these 57 patients (53%) needed only one injection to be controlled (single-shot treatment). RESULTS: Vertigo attacks were completely controlled in 95% and partially controlled in 5%, whereas hearing remained unchanged or even improved. Tinnitus as well as aural fullness were controlled in approximately 50% of the cases. CONCLUSION: Our results with this group of patients after interval-treatment or single-shot application of intratympanic gentamicin demonstrate the effectiveness of this treatment modality with very low side effects, and, although our experience is still limited, it allows for expanding the indication on early cases of Meniere's disease before permanent hearing loss occurs. Even cases of bilateral Meniere's disease can be treated successfully using this method. Cochleotoxic side effects can be prevented by treatment intervals of 7 days.

OBJECTIVE: To date, the effectiveness of balanced rehabilitation for patients with Meniere's syndrome has not been unanimously acknowledged by all physicians and physiotherapists. The purpose of this study is to assess the therapeutic efficacy of rotational exercises in the treatment of disequilibrium for patients with unilateral Meniere's syndrome. METHODOLOGY: Rotational stimuli were used to symmetrize and reduce postrotatory nystagmic response. Three reference sources were used to assess the efficacy of this management: vestibulospinal function tests: pre- and post-treatment results at the Romberg test, the Unterberger-Fukuda stepping test, the Babinski-Weil test, and gait testing with eyes closed; rotational tests: pre- and post-treatment results; and the self-perceived impact of vertigo: assessed by the Dizziness Handicap Inventory (DHI) and a scale based on the guidelines of the Japanese Society of Equilibrium Research (JSER, 1993). The JSER scale provides quantitative vertigo evaluation; the DHI reflects the patient's perceptual evaluation of handicap. RESULTS: Patients required 11 sessions (mean value) to attain subjective improvement. Of the 23 patients, only seven required optokinetic stimulation (mean requirement: three sessions). Rotational tests and dynamic tests of the vestibulospinal function improved. The DHI and JSER results show that patients' post-rehabilitation perceptual evaluation significantly improved. CONCLUSION: The objective and subjective measures of disequilibrium in patients with unilateral Meniere's syndrome were significantly improved.

Intratympanic steroids: do they acutely improve hearing in cases of cochlear hydrops?
Hillman TM, Arriaga MA, Chen DA.
Pittsburgh Ear Associates, Pennsylvania 15212-4746, USA.

OBJECTIVE: To study the acute effects on hearing of intratympanic dexamethasone in patients with cochlear hydrops. STUDY DESIGN: Retrospective review. METHODS: Patients who met established criteria for the diagnosis of Meniere's disease or had a history of fluctuating hearing loss and met hearing loss criteria for Meniere's disease, indicating cochlear hydrops, underwent a series of one to three intratympanic injections of dexamethasone in the affected ear. Follow-up audiograms were obtained 1 week after each injection and, in many patients, several months after injection. RESULTS: Fifty patients met inclusion criteria and were studied. Using the American Academy of Otolaryngology-Head and Neck Surgery reporting guidelines, hearing improved acutely in 20 of the 50 patients (40%), was worse in 2 (4%), and did not change in 28 (56%). For those who improved, the average decrease in threshold was 14.2 dB. Whether the patient had typical Meniere's disease or cochlear hydrops did not affect the response to therapy. There were no significant complications from the injections. CONCLUSIONS: Intratympanic administration of dexamethasone may acutely affect sensorineural hearing loss associated with endolymphatic hydrops. A prospective, controlled study is required.

Department of Otolaryngology, Clinical College of Shandong University, Shandong Province Hospital, Jinan 250021.

OBJECTIVE: To investigate the clinical effect of the operations in the treatment of Meniere's disease. METHOD: Twenty-one patients with Meniere's disease were treated by the operation of decompression of the endolymphatic sac. Nine patients were treated by vestibular neurectomy via retrosigmoid sinus approach. The follow-up time was between 3 and 6 years. RESULT: In 21 patients by the operation of decompression of the endolymphatic sac, vertigo was completely controlled in 11 cases, substantially controlled in 4, limitedly controlled in 4 and not controlled in 2. In 9 patients underwent vestibular neurectomy via retrosigmoid sinus approach, vertigo was completely controlled. CONCLUSION: Endolymphatic sac surgery is the first way in the operative treatments of Meniere's disease. The operation of vestibular neurectomy should be adopted only in the patients who have failed after the operation of endolymphatic sac surgery or have lost the working ability substantially.

Hearing loss after intratympanic gentamicin therapy for unilateral Meniere's Disease.
Martin E, Perez N.
Department of Otolaryngology, Hospital Casa de Salud, Valencia, Spain.

OBJECTIVE: This study set out to evaluate the hearing changes that occur during intratympanic gentamicin therapy and to correlate them with the long-term effects of the treatment on the control of vertigo and on hearing. STUDY DESIGN: This was a prospective study. SETTING: Tertiary medical center. PATIENTS: The 71 patients included in the study had been diagnosed with unilateral Meniere's Disease as defined within the 1995 American Academy of Otolaryngology-Head and Neck Surgery guidelines, and had been refractory to medical treatment for at least 1 year. INTERVENTION: Intratympanic injections of gentamicin at a concentration of 27 mg/ml were performed at weekly intervals until indications of vestibular hypofunction appeared in the treated ear. If there was a recurrence of the episodes of vertigo, an additional course of injections was performed. MAIN OUTCOME MEASURE: The 1995 American Academy of Otolaryngology-Head and Neck Surgery criteria for reporting the treatment outcome for Meniere's Disease were used. During the period of gentamicin instillation, weekly audiograms were obtained. The results of the treatment were expressed in terms of control of vertigo and hearing level. RESULTS: Vertigo was controlled by gentamicin instillation in 83.1% of the 71 patients. Two years after the treatment, hearing loss as a result of the gentamicin injections was observed in only 11 (15.5%) patients. The recurrence of spells of vertigo after having initially achieved complete control was noted in 17 (23.9%) patients. Hearing loss at the end of the treatment occurred in 32.4% of the patients, but it was transitory so that 3 months after ending the treatment it was 12.7% and after 2 years it was 15.5%. Those patients in whom no change in their level of hearing occurred during the treatment needed another course of injections and presented poorer overall control of vertigo. CONCLUSIONS: Ending weekly intratympanic injections when clinical signs of vestibular deafferentation appear results in the control of vertigo in the majority of patients. The hearing changes detected during the treatment are transitory and are the only clinical sign that predicts the response to gentamicin instillation.

[Middle ear overpressure treatment in severe Meniere's disease]
[Article in Japanese]

Department of Otolaryngology, Toyama Medical and Pharmaceutical University, Toyama.

To evaluate the therapeutic effect of middle ear pressure pulse on endolymphatic hydrops in humans, Meniett20k was used for 12 months in two severe elderly patients with definite Meniere's disease. The average number of vertigo occurrences in the 6 months before treatment and in the 12 months after treatment started was compared. Numeric values (NV) among patients were calculated and categorized into an improved group (NV = 1-40). For hearing function, the pure-tone average (PTA) before and 12 months after treatment started was compared. PTA was calculated based on the following equation: PTA = (A + 2XB + C)/4. A, B, and C were thresholds of the pure-tone audiometory at 0.5, 1.0, and 2.0 kHz. In one case, hearing function was unchanged, but deteriorated in the other. Pressure pulse treatment may thus be useful in severe cases of Meniere's, especially in the elderly, bilateral cases, and in endolymphatic hydrops in a single hearing ear.

Department of Otolaryngology, Hiroshima University School of Medicine, Hiroshima, Japan. masati@hiroshima-u.ac.jp

OBJECTIVE: To perform a trial to assess the efficacy of radical scavengers, i.e. rebamipide, vitamin C and glutathione, for the treatment of Meniere's disease (MD). MATERIAL AND METHODS: Rebamipide (300 mg/day), vitamin C (600 mg/day) and/or glutathione (300 mg/day) were given orally for at least 8 weeks to 25 patients with poorly controlled MD. RESULTS: Of 22 patients, 21 showed marked improvement of vertigo; 12/27 ears showed improvement of hearing disorders; 17/27 ears showed improvement of tinnitus; and 18/25 patients showed improvement of disability. CONCLUSION: This study suggests that treatment using radical scavengers has the potential to become an effective new therapy for MD.

Results of vestibular autorotation testing at the end of intratympanic gentamicin treatment for
Meniere's disease.
Perez N, Martin E, Garcia-Tapia R.
Department of Otorhinolaryngology, University Hospital and Medical School, University of Navarra, Pamplona, Spain. nperezfer@unav.es

OBJECTIVE: The vestibular autorotation test (VAT) examines the ocular response to voluntary horizontal and vertical head movements at frequencies for which the vestibular system is the main source for eye stabilization. The purpose of this study was to analyse the VAT results in patients with disabling Meniere's disease and to evaluate the change in VAT values once treatment with intratympanic gentamicin had terminated and clinical signs of vestibular hypofunction could be observed. MATERIAL AND METHODS: The 30 study subjects were patients diagnosed with definitive unilateral Meniere's disease that could not be controlled with medication. The vestibulo-ocular reflexes of each patient were evaluated by means of the VAT before the first injection of gentamicin and after the last injection. RESULTS: The pattern of abnormalities found in this population conformed to the selection criteria and the findings reflected a severe disabling process, with major modifications in the vestibulo-ocular reflex. At the end of treatment there was a reduction in the peak frequency of head oscillation. Furthermore, we commonly found that, in the horizontal VAT, gain and phase were reduced while in the vertical VAT some subjects registered a normal response. The phase in the horizontal and vertical VATs was most significantly reduced for oscillation frequencies of 2-3.7 Hz. CONCLUSION: This study provides further evidence that effective control of vertigo in patients with Meniere's disease can be achieved by administering intratympanic gentamicin.

Long-term hearing outcome in patients receiving intratympanic gentamicin for Meniere's disease.
Wu IC, Minor LB.
Department of Otolaryngology-Head and Neck Surgery, The Johns Hopkins University School of Medicine, Baltimore, Maryland 21287, USA.

OBJECTIVE: To determine the long-term hearing outcome in patients with intractable vertigo caused by unilateral Meniere's disease who were treated with intratympanic injection of gentamicin. STUDY DESIGN: The study was a longitudinal analysis of hearing and control of vertigo in patients with unilateral Meniere's disease who received intratympanic gentamicin. METHODS: Pure-tone thresholds and speech discrimination scores on audiometry were analyzed, along with the control of vertigo. Criteria described in 1995 by the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) were used. Patients treated with intratympanic gentamicin had "definite" Meniere's disease and had intractable vertigo despite optimal medical therapy, no symptoms suggestive of Meniere's disease in the contralateral ear, and serviceable hearing in the contralateral ear. The study analyzed the outcomes of 34 patients for whom follow-up data were available for periods greater than 24 months after intratympanic gentamicin. RESULTS: Complete control of vertigo (AAOHNS Class A) was obtained in 90% of the patients. Profound sensorineural hearing loss occurred as a result of gentamicin injection in 1 of the 34 patients (3%). When data from all patients were grouped together, hearing was improved in 5 (15%), unchanged in 23 (68%), and worse in 6 (17%) patients. This distribution of hearing outcome is similar to that in patients whose symptoms of Meniere's disease were managed with medical measures. Recurrent vertigo developed in 10 patients (29%) at an interval of 4 to 15 months after initially complete control. Treatment with additional intratympanic injection(s) of gentamicin did not result in a change in hearing. CONCLUSION: The risk of hearing loss in patients treated with infrequent intratympanic injection(s) of gentamicin is low.

[Dissection of endolymphatic duct in Meniere's disease]
[Article in Russian]
Pal'chun VT, Levina IuV.

The authors believe that endolymphatic sac (ES) surgery produces the highest and most persistent effect in comparison with all other surgical interventions in Meniere's disease (MD). Conventional views on the mechanisms underlying a beneficial effect of the ES surgery are revised and a new surgical technique is proposed. A positive effect of the operation, according to the authors, depends not on ES decompression but on the ES break taking place in separation of the dura mater from the bone skull in the outlet area of the aqueduct of the vestibule (AV). When the AV is separated from the sac, a rise in endolymphatic pressure is relieved by the endolymph pushing through the AV as it is not connected with the ES. 10 year follow-up has shown that this technique excludes subsequent endolymphatic hydrops.

Endolymphatic sac-vein decompression for intractable Meniere's disease: long term treatment results.
Ostrowski VB, Kartush JM.
Michigan Ear Institute, Farmington Hills 48334, USA.

OBJECTIVES: We sought to determine the long-term efficacy of endolymphatic sac-vein decompression surgery on patients with classic Meniere's disease. STUDY DESIGN AND SETTING: Using the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium criteria, starting stage, functional level, vertigo class, and hearing results were addressed. We studied 68 patients with classic Meniere's disease from a tertiary, private otology-neurotology practice. Patient data were gathered by retrospective chart review, questionnaire, and patient interview. All patients underwent endolymphatic sac-vein decompression with an average follow-up period of 55 months. RESULTS: Median functional level before surgery was level 4, improving to level 2 after surgery. Eighty-one percent of patients showed improvement in functional level, 12% remained stable, and 7% declined. Long-term vertigo control was 47% in class A, 25% in class B, 9% in class C, 3% in class D, and 16% in class F. Twenty percent of patients were in hearing stage I Meniere's disease; 31%, stage II; 44%, stage III; and 5%, stage IV. Eighteen percent of patients showed improvement in hearing class, 64% were stable, and 18% declined. CONCLUSION: Endolymphatic sac-vein decompression surgery is a safe, nondestructive surgical option for Meniere's disease that offers durable control of vertigo and stabilization of hearing for the majority of symptomatic patients. SIGNIFICANCE: The beneficial long-term outcome of the endolymphatic sac-vein decompression supports its continued use as a first-line treatment option in intractable Meniere's disease.

Intratympanic gentamicin for unilateral Meniere's disease: results of therapy.
Bottrill I, Wills AD, Mitchell AL.
Department of Otolaryngology Radcliffe Infirmary, Oxford, Cambridge, UK. kris.dowdeswell@orh.nhs.uk

Patients with Meniere's disease that remains refractory to conservative treatment have traditionally been subjected to ablative surgery. The purpose of this prospective study was to evaluate the use of intratympanic gentamicin in eliminating incapacitating vertigo, while preserving hearing. Over the past 8 years, 83 patients have received between 1 and 6 intratympanic injections of gentamicin in an out-patient setting, with duration of therapy titrated to individual symptom response and effect on hearing. Using established AAO-HNS guidelines, we present data on 50 patients who have a minimum of 2 years follow-up. Control or significant improvement of definitive Meniere's attacks was achieved in 92% of patients and hearing preserved or improved in 76%. Only one patient experienced profound sensorineural hearing loss. We feel this treatment option should be considered and offered to patients in whom medical treatment has failed.

Meniere's disease and gentamicin: preliminary results using the minimum effective dose and
integrated therapy.
Sala T.
Department of Otorhinolaryngology, Hospital of Piove di Sacco, Piove di Sacco, PD, Italy. t.sala@tin.it

Treatment of Meniere's disease is aimed at restoring a normal quality of life and preserving residual hearing, in view of the increasing frequency with which the contralateral ear is affected. Conventional medical treatment (diuretics + vasoactive drugs) leads to cure in a large percentage of patients (75-95%). In intractable cases, transtympanic (intratympanic) aminoglycoside therapy, associated with various techniques, is becoming widespread as an alternative to surgery. Progressive reduction of the dose introduced into the middle ear did not prevent the onset of anacusis in several patients; the variable, unpredictable permeability of the round window membrane, the object of fundamental studies in the past, explains this complication. The Author has used gentamicin transtympanically in Menierians since 1978, and has treated a total of 105 patients. He first prescribed transtympanic gentamicin therapy that did not follow, but was integrated with conventional medical treatment in 22 intractable Menierians, by instilling the minimum effective dose, to reduce the risk of hearing impairment. Preliminary results, related to stage of disease, may be summarised as follows: improvement in the quality of life, as evaluated by the American Academy of Ophthalmology & Otolaryngology Committee on Hearing and Equilibrium questionnaire (14 patients--63.63%--at point 1 and 8-36.36%--at point 2); disappearance of vertigo in 15 patients (68.18%); a minor vertigo attack in 3 and two minor attacks in 3 others not affecting quality of life; persistence of occasional unsteadiness in one patient. Hearing remained unchanged in 15 patients, improved slightly in 3 cases and worsened slightly in 2; decreased sensitivity to high tones was observed in 2 patients at the first insertion of gentamicin. According to the Author, employing integrated therapy and using the minimum effective dose of gentamicin, the risk of damage to the cochlear structures may be reduced, although not excluded, while restoring a good quality of life, even when repeat instillation is necessary.

ENT Department, University Clinic Frankfurt am Main, Frankfurt/M., Germany. adunka@em.uni-frankfurt.de

The aim of this study was to determine the efficiency of labyrinth anesthesia - the intratympanic instillation of lidocaine--in the treatment of Meniere's disease and to recall a forgotten method. Twenty-four patients (15 male, 9 female), aged from 19.7 to 80.6 years (mean: 47.8 years) with the clinical diagnosis of unilateral Meniere's disease who underwent labyrinth anesthesia in our department were included in this retrospective study. After local anesthesia of the tympanic membrane, a solution of 4% lidocaine and furfuryladenine (Kinetin) was instilled into the tympanic cavity. Patient records, a questionnaire and a physical examination were used to evaluate vertigo control, hearing loss, tinnitus, and quality of life according to the AAO-HNS criteria before and after surgery. Postoperatively, 87.5% of patients reported at least a noticeable decrease of vestibular symptoms, 66.7% of these patients were free of attacks for an average of 26.5 months. Postoperative hearing was the same or even improved in 87.5% of our patients. Tinnitus was not affected in any individual. Based on the findings presented herein, we consider labyrinth anesthesia a practicable and, due to its safety, highly recommendable therapeutic option for patients suffering from Meniere's disease.

Changing trends in the surgical treatment of Meniere's disease: results of a 10-year survey.
Silverstein H, Lewis WB, Jackson LE, Rosenberg SI, Thompson JH, Hoffmann KK.
Ear Research Foundation, Sarasota, Fla., USA. hsilverstein@aol.com

In order to discern trends in surgical procedures used to treat Meniere's disease in the United States during the 1990s, we mailed a questionnaire to 700 members of the American Otological Society and the American Neurotology Society. These physicians were asked about the frequency, results, and complications of surgical procedures for Meniere's disease that they had performed between Jan. 1, 1990, and Dec. 31, 1999. Questionnaires were returned by 137 surgeons (19.6%). Their responses indicated that the number of vestibular neurectomies, labyrinthectomies, and endolymphatic sac surgeries all decreased during 1999. Meanwhile, the use of office-administered intratympanic gentamicin therapy increased rapidly throughout the entire 10-year period, and by 1999 it had become the most frequently used invasive treatment for Meniere's disease. Surgeons now seem to reserve inpatient procedures for cases where intratympanic gentamicin fails to control vertigo.

Gentamicin perfusion vestibular response and hearing loss.
Light JP, Silverstein H, Jackson LE.
Ear Research Foundation, Florida Ear and Sinus Center, Sarasota, Florida, USA.

OBJECTIVE: To compare hearing results as a function of vestibular ablation in the treatment of Meniere's Disease, using gentamicin perfusion. STUDY DESIGN: A retrospective review of patients with Meniere's Disease treated by gentamicin perfusion of the inner ear via the MicroWick device. SETTING: A tertiary otologic referral center. PATIENTS AND INTERVENTIONS: The charts of patients treated with gentamicin perfusion via the MicroWick between the years 1998 and 2000 were reviewed. The results for patients with functional hearing in the affected ear were analyzed and were compared with the results in patients without functional hearing. MAIN OUTCOME MEASURES: Audiologic and vestibular test results as well as subjective symptoms. RESULTS: There were 45 patients who met the inclusion criteria. The averages for speech discrimination score and pure tone average before treatment were 92% and 38 dB, and after treatment were 82% and 47 dB. Patients were divided into two groups: Group 1 (20 patients), less than 75% ice air caloric reduced vestibular response (RVR); Group 2 (25 patients), those who reached greater than 75% ice air caloric RVR. There were 8 patients (17.6%) with persistent vertigo; 7 were from Group 1, and 1 was from Group 2, which was statistically significant (p = 0.007)wwww. The pure tone average dropped an average of 3 dB for Group 1 and 15 dB for Group 2. The difference in hearing loss between the two groups was statistically significant (p = 0.01). CONCLUSION: This study suggests that there is a correlation between the degree of vestibular ablation, the control of vertigo, and the risk of hearing loss. Patients with functional hearing seem to have a similar success rate for vertigo control, compared with patients who already had lost functional hearing before treatment. Future investigation may determine if less than 100% RVR, but greater than 75% RVR, is an alternative end point with adequate vertigo control and reduced risk of hearing loss.

Department of Otolaryngology, University Hospital and Medical School, University of Navarra, Pio XII 36, 31008 Pamplona, Navarra, Spain. nperezfer@unav.es

OBJECTIVE: The study aimed to analyze the results of the intratympanic injection of gentamicin as a treatment option for patients with unilateral Meniere's disease who were refractory to medical treatment. STUDY DESIGN: Prospective study in the setting of a tertiary care medical center. METHODS: Seventy-one patients with unilateral Meniere's disease according to 1995 American Academy of Otolaryngology-Head and Neck Surgery 1995 guidelines who had been unresponsive to medical therapy for at least 1 year were studied. Intratympanic injections of a prepared concentration of 27 mg/mL gentamicin were performed at weekly intervals until the development of symptoms and signs indicative of vestibular hypofunction in the treated ear. As the main outcome measure, the 1995 American Academy of Otolaryngology-Head and Neck Surgery criteria for reporting treatment outcome in Meniere's disease were used. The results of treatment were expressed in terms of control of vertigo, disability status (functional level and degree of overall impairment evaluated by the Dizziness Handicap Inventory and the University of California Los Angeles Dizziness Questionnaire), hearing level, and quantitative measurement of vestibular function. RESULTS: Vertigo was controlled in 83.1% of the 71 patients. Recurrence of vertigo spells after initially complete control was noted in 17 patients. In 13 of these patients, this was cured by another course of intratympanic injections of gentamicin. Functional level and measures of self-reported handicap were significantly and promptly lowered after treatment in the patients who attained control of vertigo. Hearing level as pure-tone average was unchanged 2 years after treatment, but hearing loss as a result of gentamicin injections occurred in 23 patients at the end of treatment and in 9 and 11 patients at 3 months and 2 years after the treatment, respectively. Vestibular function was kept normal or reduced in 49.3% of the patients, whereas in the rest of the patients vestibular areflexia was observed. Control of vertigo did not depend on the amount of vestibular damage. CONCLUSIONS: Ending weekly intratympanic injections when clinical signs of vestibular deafferentation appear can control vertigo in the majority of patients, and it is a useful alternative, together with other surgical options, for the treatment of patients with Meniere's disease who do not respond to medical treatment.

Insertion of tympanic ventilation tubes as a treating modality for patients with Meniere's disease: a short- and long-term follow-up study in seven cases.
Sugawara K, Kitamura K, Ishida T, Sejima T.
Department of Otolaryngology-Head and Neck Surgery, Jichi Medical School, Tochigi, Japan

OBJECTIVES: As a treatment for patients with Meniere's disease, insertion of a ventilating tube in tympanic membrane was carried out, and the effect of the therapeutic modality was analysed. METHODS: Seven patients (four males and three females, age ranged 35-62 years) with active Meniere's disease were placed with ventilating tubes in the affected ear and postoperative change in symptoms, i.e. incapacitating vertigo and hearing loss were investigated. Disease severity was scored and evaluated pre- and postoperatively under the guidelines proposed by the Committee on Hearing and Equilibrium in the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS, 1985). RESULTS: Of the seven cases, the number of patients and the degree in controlling vertigo after the treatment were: at 24 months (short-term) five cases with substantial, one with limited and one with insignificant control, then at 42 months (long- term) four cases with substantial, three with limited control, respectively. The degree of disability in patients at 24 and 42 months of the treatment was compatible with the level of vertigo controlling. On the other hand, patients' hearing level was not affected by the treatment. CONCLUSIONS: Exact explanation for the effect of ventilating tubes in tympanic membrane is vague and its therapeutic effect was limited. However, at least this treatment might represent a short-term effect for the reduction of persistent vertigo in some patients with Meniere's disease and so it might become a treatment option because of its simple and less-invasive procedure.

Pharmacological treatment of vertigo.
Hain TC, Uddin M.
Department of Neurology, Northwestern University, Chicago, Illinois 60611, USA. t-hain@northwestern.edu

This review discusses the physiology and pharmacological treatment of vertigo and related disorders. Classes of medications useful in the treatment of vertigo include anticholinergics, antihistamines, benzodiazepines, calcium channel antagonists and dopamine receptor antagonists. These medications often have multiple actions. They may modify the intensity of symptoms (e.g. vestibular suppressants) or they may affect the underlying disease process (e.g. calcium channel antagonists in the case of vestibular migraine). Most of these agents, particularly those that are sedating, also have a potential to modulate the rate of compensation for vestibular damage. This consideration has become more relevant in recent years, as vestibular rehabilitation physical therapy is now often recommended in an attempt to promote compensation. Accordingly, therapy of vertigo is optimised when the prescriber has detailed knowledge of the pharmacology of medications being administered as well as the precise actions being sought. There are four broad causes of vertigo, for which specific regimens of drug therapy can be tailored. Otological vertigo includes disorders of the inner ear such as Meniere's disease, vestibular neuritis, benign paroxysmal positional vertigo (BPPV) and bilateral vestibular paresis. In both Meniere's disease and vestibular neuritis, vestibular suppressants such as anticholinergics and benzodiazepines are used. In Meniere's disease, salt restriction and diuretics are used in an attempt to prevent flare-ups. In vestibular neuritis, only brief use of vestibular suppressants is now recommended. Drug treatments are not presently recommended for BPPV and bilateral vestibular paresis, but physical therapy treatment can be very useful in both. Central vertigo includes entities such as vertigo associated with migraine and certain strokes. Prophylactic agents (L-channel calcium channel antagonists, tricyclic antidepressants, beta-blockers) are the mainstay of treatment for migraine-associated vertigo. In individuals with stroke or other structural lesions of the brainstem or cerebellum, an eclectic approach incorporating trials of vestibular suppressants and physical therapy is recommended. Psychogenic vertigo occurs in association with disorders such as panic disorder, anxiety disorder and agoraphobia. Benzodiazepines are the most useful agents here. Undetermined and ill-defined causes of vertigo make up a large remainder of diagnoses. An empirical approach to these patients incorporating trials of medications of general utility, such as benzodiazepines, as well as trials of medication withdrawal when appropriate, physical therapy and psychiatric consultation is suggested.

Meniere's disease is a vestibular disorder characterized by episodic vertigo, tinnitus, fluctuant hearing loss, and ear fullness, with vertiginous attacks being the most disabling complaint. The effectiveness of conservative treatment has been variable, while surgical techniques provide more permanent relief from vertigo, but pose possible morbidity and cochlear risk. Intratympanic administration of gentamicin has been proposed as an alternative for patients with debilitating Meniere's disease who have failed to respond to standard medical treatment. The goal of such treatment is to control vertigo by partially or completely destroying the vestibular system, while at the same time maintaining hearing. In this review we present the current medical literature on pathophysiology, pharmacokinetics, administration methods, dosage, treatment protocols, and problems related to intratympanic administration of gentamicin for patients with MD. Intratympanic gentamicin administration is a simple medical modality for treatment of persistent vertigo in patients with Meniere's disease. According to recent world research protocols, we propose the instillation of gentamicin by transtympanic injection, as a quick, easy, well-tolerated, ambulatory and cost-effective technique. Drug solution concentrations should be dependent on the frequency, intensity and duration of vertigo spells, as well as the degree of existing hearing loss, thus providing progressive vertigo relief with a low possibility of secondary deafness.

Factors Influencing Quality of Life in Patients with Meniere's Disease,
Identified by a Multidimensional Approach.

Soderman AC, Bagger-Sjoback D, Bergenius J, Langius A.

PURPOSE To evaluate self-reported quality of life in Meniere's disease patients by a multidimensional approach and to identify predictors of the results.STUDY DESIGN Cross-sectional.SETTING Tertiary referral hospital centers.PATIENTS One hundred-twelve patients with Meniere's Disease.MAIN OUTCOME MEASURE Questionnaires concerning quality of life: Short Form 12 (SF-12) including the Mental Component Summary (MCS-12) and the Physical Component Summary (PCS-12), Hospital Anxiety and Depression Scale (HAD), Sickness Impact Profile (SIP), the Function Level Scale (FLS) from the American Association of Otology's criteria for reporting results of treatment of Meniere's Disease, Vertigo Symptom Scale (VSS), Hearing Disability Handicap scale (HDHS), Tinnitus Severity Questionnaire (TSQ), and Sense of Coherence (SOC) Scale.RESULTS The Meniere's patients rated their quality of life significantly worse than did healthy reference groups in both the physical and the psychosocial dimensions. The SOC affected the results of the HAD, the MCS-12, and the psychosocial dimension of the SIP. The VSS affected the results of PCS-12, both dimensions of the SIP, and the FLS. The speech perception subscale of the HDHS affected the MCS-12, and tinnitus severity affected the HAD anxiety subscale. The results of the FLS correlated with the physical dimension of quality of life.CONCLUSION The Meniere's patients experienced a worse quality of life than did healthy subjects. Vertigo mainly influenced the physical dimension, whereas tinnitus and hearing loss influenced the psychosocial dimension. Sense of coherence had an impact on the psychosocial dimension. The FLS was not sensitive enough to serve as an outcome of treatment results but needed to be complemented by quality of life instruments.

Transtympanic gentamicin perfusion for the treatment of Meniere's disease.

Schwaber MK.

Nashville EAR Institute, 4230 Harding Rd #803, Nashville, TN 37205, USA.

Meniere's syndrome is defined as the clinical disorder associated with the histopathological finding of endolymphatic hydrops (ELH). Clinically, Meniere's syndrome includes the following features: recurrent, spontaneous episodic vertigo; hearing loss; aural fullness; and tinnitus. Recognized causes of Meniere's syndrome include: 1) idiopathic, also known as Meniere's disease; 2) posttraumatic, following head injury or ear surgery; 3) post-infectious or delayed-onset Meniere's syndrome following a viral infection, usually mumps or measles; 4) late stage syphilitic; 5) classic Cogan's syndrome with episodic vertigo, hearing loss, interstitial keratitis, without syphilis; 6) variant Cogan's syndrome with episodic vertigo, hearing loss, uveitis or other ocular inflammation and without syphilis. Although Meniere's disease is by far the most common cause of Meniere's syndrome and the terms are often used interchangeably, it should be remembered that a patient has an idiopathic etiology only when the known causes have been excluded.

Posterior fossa vestibular neurotomy as primary surgical treatment of Meniere's disease: a re-evaluation.

Pareschi R, Destito D, Falco Raucci A, Righini S, Colombo S.

Unita operativa di Otorinolaringoiatria, Azienda Ospedale Legnano, Universita degli Studi di Padova, Italy. rpareschi@inwind.it

Fifty-eight patients underwent vestibular neurotomy via the posterior fossa approach between September 1992 and December 1998 at the ENT department of Legnano. All patients presented a history of disabling unilateral Meniere's disease and underwent complete neuro-otologic evaluation following the 1985 American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) guidelines. All patients underwent MRI imaging, ABR and electronystagmographic testing before surgery. Objective analysis of results is reported using the criteria published by the Committee on Hearing and Equilibrium of the AAO-HNS in 1985. According to the AAO formula, 52 patients obtained a score of 0, indicating complete control of major vertigo spells, while four were classified within the 'substantial control' group. Immediate hearing results indicated that 93 per cent of the patients maintained a level within 10 dB from the pre-operative level. Only one patient experienced a subtotal hearing loss yet retained measurable hearing. No major complications were reported. We conclude that a retrosigmoid approach to vestibular neurotomy can be considered a safe and effective procedure in relieving medically refractory vertigo in Meniere's disease while preserving the hearing. Tinnitus and long-term hearing deterioration are not influenced by the procedure.

Evoked otoacoustic emissions in patients with Meniere's disease.

de Kleine E, Mateijsen DJ, Wit HP, Albers FW.

Department of Otorhinolaryngology, University Hospital Groningen, PO Box 30.001, 9700 RB Groningen, The Netherlands.

HYPOTHESIS: This study investigated whether otoacoustic emissions (OAEs) in patients with Meniere's disease show abnormal properties. BACKGROUND: Patients with Meniere's disease experience vertigo, tinnitus, and hearing loss. OAEs are sounds generated in the inner ear, and their presence is associated with normal hearing. METHODS: Click-evoked OAEs and distortion product OAEs were measured in 100 patients with Meniere's disease. RESULTS: The incidence of the emissions in affected ears (56%) was lower than in unaffected (i.e., contralateral) ears (85%). The mean emission amplitude in affected ears was also significantly lower (2.6 dB), and the mean amplitude in unaffected ears was lower than in normal-hearing ears (5.3 dB). These differences were likely caused by the hearing loss involved. Further, ears with OAEs clearly showed smaller hearing losses than ears without OAEs (24-dB difference). The average hearing loss showed correlations with the emission amplitudes, although this correlation was not very strong; when plotted against the smallest hearing loss, a certain upper boundary for the emission amplitude was present. Also, the amplitude of click-evoked OAEs showed a considerable correlation with the largest of the three distortion product OAEs. CONCLUSION: OAEs in patients with Meniere's disease differed from those in normal-hearing ears but did not differ from those in non-Meniere's ears with equivalent hearing loss. This was best observed by comparing emission amplitude with smallest hearing loss instead of mean hearing loss.

[Follow-up assessment of intratympanic gentamicin therapy and Saccotomia in Meniere's Disease]

[Article in German]

Tauber S, Jager L, Issing WJ.

Klinik und Poliklinik fur Hals-, Nasen- und Ohrenkranke, Ludwig-Maximilians-Universitat Munchen, Germany.

BACKGROUND: The intratympanic application of ototoxic antibiotics and saccotomia have been well documented in severe cases of one-sided Meniere's disease for 30 years now. Both treatment methods are still subject to controversial discussion. PATIENTS AND MATERIAL: This study includes 8 patients suffering from persistent one-sided Meniere's disease after treatment with gentamicin application and additional saccotomia (n=2). We performed follow-up visits including the assessment of hearing ability, vestibular function and cranial MRI, 2-10 years after onset of treatment. RESULTS: After therapeutic interventions 7 patients reported to be healed of their symptom vertigo. In 4 patients the gentamicin-treated vestibular organ did not respond to thermic stimulus at the time of follow-up examination. Auditory threshold shift was observed in 3 patients (1 permanent, 2 temporary), whereas hearing threshold improved in 2 patients. Tinnitus was attenuated in 3 patients, while 1 patient suffered from posttherapeutic onset of tinnitus. Morphological and structural changes due to Meniere's disease and treatment procedures were ruled out by cranial MRI. CONCLUSION: The intratympanic application of ototoxic medication is a safe and effective treatment method in severe cases of Meniere's disease. Saccotomia should be considered as therapeutic regimen for persistent symptoms after repeated application of gentamicin.

Multivariate vestibular testing: Laterality of unilateral Meniere's disease.

Dimitri PS, Wall III C, Rauch SD.

Harvard University -- Massachusetts Institute of Technology Division of Health Sciences and Technology, Boston, USA.

This paper discusses the use of vestibular testing to discriminate between right (n = 29) and left (n = 27) Meniere's disease. We examined reduced vestibular response (RVR), directional preponderance, and spontaneous and positional nystagmus measurements from electronystagmography, as well as the asymmetry measurements from the sinusoidal harmonic acceleration test, to determine whether multivariate logistic regression could improve upon the discrimination performance of RVR alone. We found that patients with a spontaneous or positional nystagmus often had a "recovery nystagmus", beating in the opposite direction of that predicted for an acute lesion. When present, the direction and magnitude of such nystagmus could be used in the classification algorithm to increase the discriminatory power over RVR alone, but in these patients the rotation test asymmetry measurements were rendered useless. In the absence of spontaneous or positional nystagmus, asymmetry measurements significantly enhanced right/left discrimination. Directional preponderance was insignificant in determining the side of lesion.

Multivariate vestibular testing: Thresholds for bilateral Meniere's disease and aminoglycoside ototoxicity.

Dimitri PS, Wall III C, Rauch SD.

Harvard University -- Massachusetts Institute of Technology Division of Health Sciences and Technology, Boston, USA.

Although patient symptoms and an audiogram can typically identify the affected ear or ears in Meniere's disease, there are some cases where this differentiation is problematic. This paper concentrates on the sole use of vestibular test data to discriminate between unilateral and bilateral Meniere's disease. Patients that were known to have peripheral unilateral vestibular hypofunction (n = 104) were used as learning groups to define a region in multidimensional measurement space consisting of four vestibular test scores which summarized data from electronystagmography, sinusoidal harmonic acceleration, and computerized dynamic posturography tests. A multivariate boundary was created from the unilateral learning group that determined thresholds for identifying bilateral vestibular hypofunction. Patients with bilateral Meniere's disease (n = 23) and with bilateral ototoxicity (n = 19) were then used as test subjects to determine the sensitivity of the multivariate boundary. Results showed up to a increase in estimated test sensitivity (specificity = 95%) from 67%(current method)to 82%(new method)in identifying bilateral vestibular hypofunction.

[Intratympanic gentamycin in association with human fibrin glue in the treatment of
Meniere's disease: preliminary results]

[Article in Italian]

Casani AP, Dallan I, Sellari-Franceschini S, Nuti D.

Dipartimento di Neuroscienze, Sez. ORL, Universita di Pisa. mailto:acasani@leonet.it

The treatment of Meniere's disease (Md) with intratympanic gentamicin has rapidly become one of the most widespread alternatives to surgery in this disorder. Numerous studies, employing different protocols, have reported the use of this antibiotic in the treatment of disabling forms of Md, with success rates in the control of vestibular symptoms varying from 73 to 100%, associated with a rate of hearing complications varying from 0 to 75%. We have reported the results of a preliminary experience carried out in 10 patients affected by monolateral Md who were managed with ablation treatment effected with a mixture of gentamicin and human fibrin glue. Upon follow-up examination after one year, all of the patients presented a marked reduction in vestibular reflectivity on the side treated. The vertigo score was zero in all of the patients, showing that the vertigo symptoms were entirely under control. When patients were asked to rate their disability, vertigo was assessed as completely under control in 7 patients and substantially under control in the remaining 3. None of the patients presented any loss of hearing. On the basis of this experience, we propose a standardized protocol which, using an extremely low overall dose of gentamicin, enables elevated success rates to be obtained with the lowest possible number of injections, thus minimizing the risks to hearing. Intratympanic gentamicin associated with a fibrin carrier in Md appears to enable a standardized dose of the drug to be employed, resulting in a decided reduction in the number of administrations and in the overall dose of the drug applied. This makes it possible, with equal benefits in vertigo control, to significantly minimize any hearing loss.

Stop the spinning: diagnosing and managing vertigo.

Sandhaus S.

Geriatric Programs, Moses Taylor Hospital, Scranton, PA, USA.

Differentiating vertigo from other forms of dizziness presents a diagnostic challenge. Extensive investigation, however, can help reveal vertigo's true etiology: life-threatening central lesions or debilitating, but benign, peripheral causes. Here, learn to assess vertigo using physical examination, history, and diagnostic procedures. Also, manage symptoms of common vestibular disorders, such as benign paroxysmal peripheral vertigo, labyrinthitis, and Meniere's disease.

[Intra-tympanic gentamicin in the treatment of Meniere's disease: preliminary results]

[Article in Spanish]

Hospital Universitario Miguel Servet de Zaragoza. crismaring@yahoo.com

In the majority of patients suffering of Meniere's disease, medical treatment is sufficient to control symptoms, albeit, in a small number of them, the high intensity and frequency of vertigo spells makes necessary to adopt more aggressive measures, like intratympanic or general aminoglycoside administration, as well as surgical procedures. We present a prospective and longitudinal descriptive study with the results of intratympanic gentamycin in 24 patients labeled of Meniere's disease in the Otolaryngology Department of "Miguel Servet Hospital" in the last two years, after a follow-up period of more than a year, during which controlled medical treatment had been proved unsuccesfull. We go over the efficacy in terms of frequency of vertigo crisis, audition average, logoaudiometry and functional level. We obtained good results over vertigo control (types A and B of the objective criteria based in the improvement index after treatment) in 16 out of the 24 patients (66.6%), (13 were type A with total absence of crisis and 3 were type B) and an acceptable result (type C) in three of them (12.5.%). In the other five patients (20.83%) results were disappointing (types D and E) compelling to apply surgical treatment. We have tried to evaluate intratympanic gentamycin as an alternative treatment to more aggressive technics and we consider it to be a good option, with a low risk and scarce complications in the no pharmacologically controlled Meniere's disease patients.

Intermittent pressure therapy of intractable Meniere's disease using the Meniett device:
a preliminary report.

Gates GA, Green JD Jr.

Department of Otolaryngology-Head and Neck Surgery, University of Washington School of Medicine, Seattle, Washington 98195-7923, USA. ggates@u.washington.edu

HYPOTHESIS: Treatment with the Meniett device, which applies intermittent micropressure pulses to the inner ear through a tympanostomy tube, is effective in controlling vertigo in people with intractable Meniere's disease. STUDY DESIGN: Short-term, preliminary descriptive report. METHODS: Ten patients with intractable vertigo despite adequate medical therapy elected to use the Meniett device. After placement of a standard tympanostomy tube, the patient self-administers the Meniett device three times daily. RESULTS: The follow-up ranged from 3 to 11 months with an average of 8 months. All 10 patients responded to the therapy with vertigo control in 9 of 10 and a 50% reduction in the 10th case. There was a mean hearing gain of 6 dB, which was statistically significant. There were no major complications. Two subjects required tube reinsertion during the 8 months of follow-up. CONCLUSIONS: Use of the Meniett device is an effective and safe option for people with intractable vertigo from Meniere's disease.

Immunologic and serologic testing in patients with Meniere's disease.

Ruckenstein MJ, Prasthoffer A, Bigelow DC, Von Feldt JM, Kolasinski SL.

Department of Otorhinolaryngology-Head and Neck Surgery and Division of Rheumatology, University of Pennsylvania, 3400 Spruce Street, 5 Ravdin, Philadelphia, PA 19104, U.S.A. michael.ruckenstein@uphs.upenn.edu

OBJECTIVE: To establish the value of immunologic and serologic testing in patients with Meniere's disease. STUDY DESIGN: Prospective cohort. SETTING: University-based, tertiary care balance center. INTERVENTION: Patients with active unilateral or bilateral Meniere's disease underwent testing, including antinuclear antibodies, anti-DNA antibodies, rheumatoid factor, complement levels, anti-Sjogren syndrome A and B antibodies, sedimentation rate, antiphospholipid antibodies, Western blot for anticochlear antibodies (anti-heat shock protein 70), microhemagglutination test for Treponema pallidum, and Lyme titers. OUTCOME MEASURES: Results of laboratory tests. RESULTS: In patients with unilateral Meniere's disease (n = 40), 27% demonstrated elevated antiphospholipid antibody titers (population norm, 6-9%). The majority of these patients manifested negative assays on the other tests listed above. In patients with bilateral Meniere's disease (n = 18), elevations in antinuclear antibody titers (38%) were the most notable finding. As part of a broader study of patients with progressive hearing loss, four patients with positive syphilis titers were identified; however, none of these patients complained of vertigo. CONCLUSION: In general, the results of this study do not support the hypothesis that immune or infectious pathologies are involved in the pathogenesis of unilateral Meniere's disease. In particular, Lyme disease does not seem to cause labyrinthine disease. However, the potential role of the thrombogenic antiphospholipid antibodies must be further investigated. Patients with bilateral Meniere's disease may be more likely to have a systemic autoimmune process.

Efficacy of increased gentamicin concentration for intratympanic injection therapy in Meniere's disease.

Abou-Halawa AS, Poe DS.

Faculty of Medicine, Suez Canal University, Ismailia, Egypt.

OBJECTIVES: Update of ongoing case series of intratympanic gentamicin use in intractable Meniere's disease. Comparison of the treatment results of two gentamicin concentrations: 30 mg/ml and 40 mg/ml. STUDY DESIGN: Retrospective case-matched review of an ongoing protocol. SETTING: Ambulatory visits in an office setting. PATIENTS: Eighty-seven patients were included in this study according to the 1995 guidelines of the American Academy of Otolaryngology-Head and Neck Surgery (AAO-HNS) for reporting treatment results of Meniere's disease. INTERVENTION: Intratympanic injection of a buffered gentamicin solution (30 mg/ml) was used in 44 patients (Group 1) in years 1992 to 1995. Stock gentamicin solution (40 mg/ml) was used in 43 patients (Group 2) in years 1996 to 1999. Treatment was titrated for each patient, and the hearing was strictly monitored. The endpoint of treatment was the complete cessation of vertigo spells. MAIN OUTCOME MEASURES: Hearing results, vertigo control scores, and ice water caloric testing responses were analyzed after 24 months of follow-up. Thirty-two patients from each group were selected for case-matched statistical analysis. RESULTS: Four or fewer gentamicin injections were used in 70% of Group 1 patients and 96% of Group 2 patients. In Group 1, vertigo control was achieved in 81% of patients, and the hearing remained the same or was improved in 68% of patients. In Group 2, vertigo control was achieved in 72% of patients, and the hearing remained the same or was improved in 81% of patients. Treatment was aborted in four patients of Group 2 for early reversible hearing loss, and 31 of 39 patients (79%) who completed the protocol experienced lasting vertigo control. There was a trend for longer-lasting vertigo control in the Group 2 patients. CONCLUSION: It was concluded that increasing the gentamicin concentration to 40 mg/ml probably produces similar rates of vertigo control as those of the lower dose, at least initially, but requires fewer injections. The higher dose did not increase the risk of hearing loss if treatment was stopped at the first indication of injury. A larger study is needed to confirm the trend of improved long-term hearing results in patients treated with the 40 mg/ml solution.

Benign paroxysmal positional vertigo in patients with Meniere's disease treated with
intratympanic gentamycin.

Perez N, Martin E, Zubieta JL, Romero MD, Garcia-Tapia R.

Department of Otolaryngology, University Hospital and Medical School, University of Navarra, Spain. nperezfer@unav.es

OBJECTIVES: To analyze the incidence and characteristics of benign paroxysmal positional vertigo (BPPV) in patients with Meniere's disease who did not respond to medical treatment and to whom intratympanic gentamycin treatment was proposed. STUDY DESIGN: This is a retrospective analysis of the patients in our database. A complete otoneurologic bedside examination of each patient, including assessment of positional nystagmus, was performed at the time of diagnosis and during the follow-up. RESULTS: Nine of 90 patients with Meniere's disease also had BPPV, which manifested in different ways. In 3 patients, BPPV preceded the onset of Meniere's symptomatology in the same ear; in 1, BPPV manifested after treatment for Meniere's disease had ended and the patient was in complete control of the spontaneous spells of vertigo; in 5 cases, recurrences of both Meniere's disease and the positioning symptomatology coincided. Treatment for each condition was conducted independently and favorable results were obtained after long-term follow-up when Meniere's disease and BPPV did not coincide simultaneously. In the group manifesting symptoms of both disorders at the same time, gentamycin treatment with the Canalith Repositioning Procedure and/or Semont maneuver partially resolved the symptoms. CONCLUSIONS: In the context of Meniere's disease, the sequence of appearance of BPPV relative to the spontaneous episodes must be taken into account when planning the treatment for each of the disorders, which should be considered independently. This pattern could also influence the prognosis for each disorder.

Intentional ablation of vestibular function using commercially available topical gentamicin-betamethasone eardrops in patients with Meniere's disease: further evidence for topical eardrop ototoxicity.

Kaplan DM, Hehar SS, Bance ML, Rutka JA.

Department of Otolaryngology, University Health Network, Toronto General Hospital, University of Toronto, Ontario, Canada.

OBJECTIVE: To determine whether the controversial findings of suspected ototoxicity from commercially available gentamicin sulfate and betamethasone sodium phosphate eardrops can be used in a therapeutic fashion to ablate (or attenuate) vestibular function in patients with unilateral Meniere's disease. STUDY DESIGN: Prospective case review. METHODS: At a tertiary care dizziness unit at the University Health Network, Toronto General Hospital, University of Toronto (Toronto, Ontario, Canada), adults with unilateral Meniere's disease undergoing intratympanic ablation therapy were studied. After insertion of a tympanostomy tube with the patient under local anesthesia, patients instilled gentamicin containing eardrops three times daily until they became vertiginous for longer than 24 hours and then for an additional 2 days longer or for 1 month, whichever came first. Electronystagmographic caloric test responses were measured before treatment using bithermal water caloric and after treatment using air caloric tests. Main outcome measures included clinical titration of drops to the onset of prolonged vertigo. As well, post-treatment findings on electronystagmography and audiometry were compared with pretreatment testing. RESULTS: Twenty patients were available for review. Fifteen patients had a significant reduction in caloric test responses compared with pretreatment values; among them, 10 patients had absent air caloric test responses on the treated side. In 10 patients hearing worsened according to the 1995 American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium Guidelines for reporting in Meniere's disease. CONCLUSIONS: Topical gentamicin-betamethasone eardrops can pass through a tube into the middle ear, where they may prove primarily vestibulo-ototoxic patients with Meniere's disease. The study further confirms clinical observations that gentamicin-containing eardrops might prove ototoxic, especially in noninflamed ears with a tympanic membrane defect.

Perilymphatic pressure measurement in Meniere's disease.

Ayache D, Plouin-Gaudon I, Bouzerar K, Elbaz P.

Department of Otorhinolaryngology, Fondation Adolphe de Rothschild, Paris, France.

The aim of this study was to evaluate the perilymphatic pressure, by means of the MMS-10 Tympanic Displacement Analyzer (TDA), in patients with Meniere's disease (MD). Measurements were performed in 37 patients with MD and in 14 normal-hearing subjects. Data were collected from 3 groups: healthy ears of normal-hearing subjects, unaffected ears of patients with MD, and affected ears of patients with MD. Analysis of the results obtained with the TDA showed no significant differences between the 3 groups. Several hypotheses could explain this lack of difference: 1) perhaps indirect measurement of perilymphatic pressure with the TDA is not relevant; 2) perhaps hyperpressure of the inner ear is not the physiological basis for the clinical triad of MD; or 3) perhaps endolymphatic hydrops does not produce changes in perilymphatic pressure. The results of this series indicate that the TDA is not useful in the evaluation of patients with MD.

Revision surgery after saccotomy for Meniere's disease: does it make sense?

Schwager K, Baier G, El-Din N, Shehata-Dieler W, Carducci F, Helms J.

Department of Otolaryngology, Head and Neck Surgery, University of Wurzburg, Josef-Schneider-Str. 11, Germany. k.schwager@mail.uni-wuerzburg.de

Saccotomy is an established surgical treatment for Meniere's disease that involves exposing and opening the endolymphatic sac and draining the endolymph. However, in patients experiencing recurrent vertigo after saccotomy, it is questionable whether revision saccotomy should be recommended as opposed to more invasive procedures, such as neurectomy of the vestibular nerve. To determine the utility of revision saccotomy, we conducted a retrospective study of 29 patients undergoing this procedure for recurrent vertigo. Patient charts were reviewed for the re-occurrence of any vertiginous symptoms and outcomes with regard to hearing results and post-operative complications. An attempt was made to correlate vertigo status post-revision with surgical findings at the time of revision. After an average follow-up of 20 months, 18 patients (62%) were free of vertigo, and four patients (14%) had a significant decrease in the frequency and intensity of vertiginous attacks. Two patients (7%) relapsed after a vertigo-free period of 18 months, and five patients (17%) experienced no clinical improvement after revision surgery. In patients with a successful sac revision, a common finding at the time of revision was new bone formation in the endolymphatic sac area (n=11), which may have caused blocking of the endolymphatic drainage. Our results demonstrate that revision saccotomy should be considered for recurrent Meniere disease before other, more invasive, surgical options.

A case against spiral ligament atrophy as a cause of Meniere's disease.

Harris JP, Keithley EM.

Division of Otolaryngology-Head and Neck Surgery, University of California and Research Service of the Department of Veterans Affairs, San Diego 92103-8895, USA. jpharris@ucsd.edu

The etiology of Meniere's disease and endolymphatic hydrops has been very difficult to determine. In order to develop rational therapies for patients with Meniere's disease the etiology needs to be established. In the current study an examination was made of the spiral ligament in temporal bones from individuals with Meniere's and endolymphatic hydrops and normal control temporal bones. No evidence of atrophy in either the length or width or the fibrocyte cell density was seen in the temporal bones with Meniere's disease. The role of the spiral ligament in the development of endolymphatic hydrops is still unclear. Copyright 2002 S. Karger AG, Basel

Clinical presentation of Meniere's disease in children is not as typical as in adults. The triad of vertigo, tinnitus and deafness are not usually elicited, diagnosis often being made after years of follow up and batteries of investigation. A case of Meniere's disease in a 3-year-old boy is presented. The diagnosis was only obvious at the age of 8 when the triad of vertigo, deafness and tinnitus were present. His disease progressed despite a trial of intratympanic gentamicin injections and endolymphatic sac decompression. Vestibular nerve section was subsequently performed for his intractable disease. Following the procedure he was asymptomatic and able to attend school.

Hearing loss following intratympanic instillation of gentamicin for the treatment of
unilateral Meniere's disease.

Kaplan DM, Nedzelski JM, Al-Abidi A, Chen JM, Shipp DB.

Department of Otolaryngology, Sunnybrook and Women's College Health Science Centre and the University of Toronto, Ontario.

OBJECTIVE: To determine the incidence, extent, and time course of hearing loss following instillation of intratympanic gentamicin using a predetermined fixed protocol for incapacitating unilateral Meniere's disease and to determine whether such loss is associated with any identifiable risk factors. STUDY DESIGN: A retrospective analysis of all patients treated with intratympanic gentamicin between 1988 and 1998 using American Academy of Otolaryngology-Head and Neck Surgery reporting guidelines (1985 and 1995). A predetermined regimen using a fixed dose (gentamicin 26.7 mg/mL administered three times daily for 4 consecutive days) was used. METHODS: The records of patients treated with this particular protocol were reviewed. The relationship between pretreatment hearing acuity, pretreatment bithermal caloric response, duration of symptoms, and previous treatment to post-treatment hearing were analyzed with respect to hearing. RESULTS: Complete vestibular and audiologic data over a minimum 2-year follow-up were available for 85 individuals. Sixty-three patients (74.1%) had unchanged or improved hearing, and 22 patients (25.9%) realized hearing loss. In 80% of the latter, it occurred during the first month post-treatment. When hearing acuity at the 1-month post-treatment interval remained unchanged (91.1%), it was likely to remain so over the next 23 months. A significantly higher incidence of profound hearing loss was noted in patients who developed hearing loss in the first month, as compared with those who developed hearing loss at a later period (p = .0207, relative risk = 1.5). Re-treatment was not associated with hearing loss. The only identifiable risk factor for developing hearing loss was pretreatment hearing acuity stages 3 and 4 (pure-tone average > 40 dB) (p = .022, relative risk = 1.5). CONCLUSION: Hearing loss is a recognized complication of treatment with intratympanic gentamicin, occurring in approximately 26% of individuals. In those individuals in whom hearing acuity has remained unchanged after the first month interval, significant worsening of hearing is unlikely, and patients can be reassured accordingly.

Continuous gentamicin therapy using an IntraEAR microcatheter for Meniere's disease:
a retrospective study.

OBJECTIVES: The study goals were to evaluate the safety and effectiveness of continuous gentamicin therapy (CGT) in the treatment of Meniere's disease and to evaluate the effect of flow rate. STUDY DESIGN: In a retrospective study, physicians who were known to have used CGT in the treatment of Meniere's disease were asked to report patient information on a standardized data collection form. RESULTS: In patients treated with low-flow CGT, vertigo was eliminated or substantially controlled in 90%, tinnitus was improved in 69%, pressure was improved in 77%, hearing was worse in 23%, and vestibular function was ablated in only 14% of patients. CONCLUSION: On the basis of an average 10-month follow-up period, of the methods currently available to treat Meniere's patients with gentamicin, low-flow CGT seems to provide an excellent combination of vertigo control and tinnitus and pressure improvement, with a relatively low risk to hearing and vestibular function. SIGNIFICANCE: The clinical use of low-flow CGT appears to be justified based on these data.

[New possibilities in the treatment of Meniere's disease]

[Article in Serbo-Croatian (Cyrillic)]

Milanovic N, Kitanoski B, Ristic B, Jacimovic V.

The results of the treatment of Meniere's disease by intratympanic instillation of gentamicin in 32 patients over a 24-months period were analyzed. The receded vestibular function was found in 96.8% patients, whereas in the remaining 3.2% pronounced vestibular hypofunction was observed. One month after the treatment vertiginous attacks disappeared in all the patients. However, three months after the treatment infrequent episodes of mild degree vertigo and mild unsteadiness that did not require additional intratympanic gentamicin application appeared in 15% of the patients with Meniere's disease. The vertiginous attacks ceased or were pronouncedly reduced in 85% of the patients. The unstable vestibular hypofunction was successfully converted into stabilized, centrally compensated areflexia. Intratympanic gentamicin exerted better results than the other invasive therapies for intractable Meniere's disease.

Vascular occlusion in the endolymphatic sac in Meniere's disease.

Friberg U, Rask-Andersen H.

Department of Otorhinolaryngology-Head and Neck Surgery, Uppsala University Hospital, Sweden.

In 2 patients with severe Meniere's disease (MD), there was histologic evidence of occlusion of the vein of the vestibular aqueduct (VVA). This finding coincided with total or partial occlusion of numerous small vessels around the endolymphatic sac (ES), flattening of epithelium, extensive perisaccular fibrosis, and signs of new bone formation. Ultrastructural analysis of the occluding material showed foci with dense connective tissue, calcification, lipid deposits, and layers of basement membrane, sometimes concentrically arranged. The exact nature of the occluding material was unknown. In another 2 MD patients, the VVA was not visualized, and the ES vessels showed no signs of occlusion. Seven controls with acoustic schwannoma or meningioma had normal vasculature. The presence of vascular impairment in the ES in MD patients indicated that altered hemodynamics may contribute to the pathogenesis of endolymphatic hydrops and MD.

OBJECTIVES: To characterize hearing loss, tinnitus and associative factors in Meniere's disease. METHODS: From our vertigo database consisting of 1356 patients, we retrieved 243 patients with Meniere's disease (MD). RESULTS: Hearing loss was the initial symptom in 13% of cases. Altogether 64% (n=133) of the patients stated that their hearing was reduced during the vertigo attack. The hearing deteriorated more likely during the vertigo attack if the vertigo attack was very intense [r(206)=0.19]. Tinnitus was the initial symptom in 5% of cases. The tinnitus was mild in 38% (n=90), moderate in 32% (n=76) and severe in 30% (n=72) of patients. The intensity of tinnitus correlated with the occurrence of drop attacks [r(237)=0.29], vertigo provoked by head positioning [r(235)=0.25], by physical activity [r(230)=0.33], or by pressure changes [r(239)=0.27]. CONCLUSION: Prolonged disease causes deterioration of hearing. Intense tinnitus is common in MD and is more often seen in late stage of the disease.

Genetic basis of familial Meniere's disease.

Fung K, Xie Y, Hall SF, Lillicrap DP, Taylor SA.

Department of Otolaryngology, London Health Sciences Centre, University of Western Ontario, London.

The genetic basis of familial Meniere's disease (MD) is unclear. We present a genetic investigation of six individuals in two families with familial MD. Linkage analysis was performed using polymorphic DNA markers linked to the human leukocyte antigen (HLA) locus that map to chromosome 6p. We have demonstrated the presence of anticipation in successive generations and the absence of HLA association. This is the second report of anticipation in familial MD in the literature, and it suggests that efforts should be directed toward finding a trinucleotide expansion as a possible genetic lesion in this uncommon disorder.
