BACKGROUND: Incidence rates of Meniere's syndrome/disease vary considerably from 157 per 100 000 in the United Kingdom to 15 per 100 000 in the United States. A wide range of treatments are used for the treatment of the condition with no consensus on the most effective intervention.

OBJECTIVES: To assess the effectiveness of the Meniett device in reducing the frequency and severity of vertigo in Meniere's syndrome/disease.

SEARCH METHODS: The Cochrane Ear, Nose and Throat Disorders Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific abstracts; ICTRP and additional sources for published and unpublished trials were searched. The date of the last search was 13th May 2014.

SELECTION CRITERIA: Four randomised controlled trials (RCTs) were identified that compared the efficacy of the Meniett device versus a placebo device in patients with Meniere's 'disease' as defined by the AAOO criterion.

DATA COLLECTION AND ANALYSIS: Two review authors independently assessed study eligibility and risk of bias and extracted data. The outcome data were dichotomous for all the included trials.

MAIN RESULTS: The four RCTs compared 123 patients with the Meniett device against 114 patients with the placebo device from four RCT's over a follow-up period of 2 weeks to 4 months. There was a significant overall 61% reduction in the frequency of vertigo in both groups (mean no vertigo days per month of 8-3). However, this reduction was not significantly different between the two groups in any study or on meta-analysis [mean difference in vertigo-free days between Meniett and placebo device of 0.77 days over a 1-month period (95% CI - 0.82, 1.83) P = 0.45]. There were also no substantive data to support a greater reduction in the severity of the vertigo or any other outcome with the Meniett device compared with the placebo device.

AUTHORS CONCLUSIONS: No evidence was found to justify the use of the Meniett device in Meniere's syndrome/disease.
