To determine the incidence of vertigo after cochlear implantation and to describe appropriate intervention. A retrospective case review. All adults receiving cochlear implants at the Atlanta Cochlear Implant Group from 1995 through 1999. Vertigo was identified through subjective reports, provoked nystagmus, and static force plate evaluation. Vestibular therapy was initiated for each vertiginous patient after cochlear implant surgery. The outcome of treatment was resolution of vertigo and return to functional status. Approximately three-quarters of the adults with implants experienced vertigo or imbalance. Vestibular therapy was beneficial in alleviating these symptoms. A significant number of patients experienced vertigo after cochlear implant surgery. Vestibular therapy is a successful treatment of condition.
