Posterior fossa vestibular nerve section for the management of peripheral vertigo.

Patients with vertigo resistant to conservative treatment require surgical management. Between March 1991 and August 1996, vestibular nerve sections were performed in 108 patients with peripheral vertigo not responding to conservative treatment. The diagnoses were classic Ménière's disease in 96 patients and recurrent vestibulopathy in 12 patients. Combined retrosigmoid retrolabyrinthine (n = 106) and retrolabyrinthine (n = 2) approaches were used. Patients were grouped according to follow-ups of less than 2 years and more than 2 years. In the former group (n = 49), hearing preservation and vertigo control were achieved in 93.9% and 100%, respectively. In the latter group (n = 59) the rates were 89.8% and 96.6%, respectively. Overall complications were uncommon. Three patients had cerebrospinal fluid leakage and one had total hearing loss. According to our results, posterior fossa vestibular nerve section was found to be an effective treatment for the management of patients with intractable vertigo.
