Archive ouverte
International audience. Objective: To evaluate the efficacy of portable Meniett low-pressure pulse generator (Medtronic Xomed, Jacksonville, FL) in Meniere disease.Study Design: Randomized, double-blind, placebo-controlled, multicenter trial carried out in 17 academic medical centers.Methods: One hundred twenty-nine adults presenting Meniere disease (American Academy of Otolaryngology–Head and Neck Surgery criteria) not controlled by conventional medical treatment were included. The protocol included three phases: 1) placement of a transtympanic tube and evaluation of its effect (if resolution of symptoms, the patient was excluded); 2) randomization: 6-weeks treatment with Meniett (Medtronic Xomed) or placebo device; 3) removal of the device and 6-week follow-up period. The evaluation criteria were the number of vertigo episodes (at least 20 minutes with a 12-hour free interval) and the impact on daily life as assessed by self-questionnaires.Results: Ninety-seven patients passed to the second phase of the study: 49 and 48 patients received the Meniett (Medtronic Xomed) or the placebo device, respectively. In the placebo group, the number of vertigo episodes decreased from 4.3 ± 0.6 (mean ± standard error of the mean) during the first phase to 2.6 ± 0.5 after 6 weeks of treatment, and to 1.8 ± 0.8 after the removal of the device. Similar results were observed in the Meniett device (Medtronic Xomed) group: 3.2 ± 0.4 episodes during the first phase, 2.5 ± after 6 weeks of Meniett device (Medtronic Xomed) treatment, and 1.5 ± 0.2 after the third phase.Conclusion: An improvement of symptoms was evidenced in all patients, with no difference between the Meniett (Medtronic Xomed) and the placebo device groups. The decrease in the number of vertigo episodes could be explained by an effect of the medical care.
