Abstract

Posterior fossa vistibular neurectomy has become one of the most effective surgincal procedures for control of vertigo symptoms in Menière's disease. A small group patients continue to have vertigo and demonstratablke vestibular function by electronystagmography (ENG) post-operatively. Another group of patients may have also. In an effort to correlate hitological findings with clinical outcome, nerve biopsies were comapared with clinical, audiometric and ENG results. Results of this study demonstratge that complete reduction of vestibylar response (on calorica testing) and clinical cure of vertigo can be obtained despite a variable number of nerve fibres at vestibular neurectomy.
