Posterior semicircular canal occlusion for benign paroxysmal positional vertigo.

For the small group of patients with benign paroxysmal positional vertigo that does not resolve with time or conservative treatment measures, posterior semicircular canal occlusion is considered. In the past 2 years, eight patients have undergone posterior semicircular canal occlusion at the Chicago Otology Group. All patients noted resolution of their positional vertigo. No complications were observed, particularly no sensorineural hearing loss was noted. A several-week period of disequilibrium is typical and appears to be the most bothersome aspect of the surgery to the patient.
