The role of vestibular nerve section in Menière's disease.

The role of vestibular nerve section (VNS) surgery in the management of Menière's disease is considered by prospective analysis of a large series of 531 patients treated by the author over a period of 11 years. Twenty-seven percent were referred by their primary care physicians, while the rest were secondary (45.6%) or tertiary (27.3%) referrals. Overall, 62 (11.7%) Menière's patients underwent 63 VNS procedures. This surgery was undertaken more frequently in the secondary and tertiary referral patients (14.2%) than in the primary referrals (5.5%). The retrolabyrinthine technique was the preferred approach in almost 90% of ears. The results and complications of these and other surgical options are discussed in an attempt to define the present role of VNS in intractable Meniere's disease. Vertigo was abolished after VNS in 93% of cases. Compensation was significantly impaired in 12.9%. All these patients had contralateral Menière's disease or marked labyrinthine hypofunction. Although highly effective and associated with few postoperative complications, VNS is generally reserved for sac failures, though may be appropriate as a primary procedure in severe unilateral cases.
