Endolymphatic sac drainage for the treatment of Meniere's disease

Abstract

Objective: To describe the results obtained with endolymphatic sac drainage in patients with Meniere's disease. Method: A retrospective case review study was conducted of 95 Meniere's disease patients who underwent endolymphatic sac drainage in a tertiary care referral centre, after failing a long course of medical management. The main outcome measures were vertigo control and hearing preservation. Results: In patients with unilateral disease, vertigo control was obtained in 94.3 per cent of patients. A significant improvement in cochlear function was seen in 14 per cent of patients, and hearing was preserved or improved in 88 per cent. For the bilateral group, vertigo control was obtained in 85.7 per cent of patients and cochlear function improved in 28 per cent. Hearing preservation was attained in 71 per cent of these patients. Conclusion: Endolymphatic sac drainage is a good surgical option for patients with incapacitating endolymphatic hydrops, providing a high percentage of vertigo control and hearing preservation.
