Vertigo after cochlear implantation.

BACKGROUND: Historically, vertigo after cochlear implantation has not been frequently documented. This differs from the authors' experience in reviewing all adults who underwent implantation at their center from 1995 through 1999. OBJECTIVE: To determine the incidence of vertigo after cochlear implantation and to describe appropriate intervention. STUDY DESIGN: A retrospective case review. PATIENTS: All adults receiving cochlear implants at the Atlanta Cochlear Implant Group from 1995 through 1999. INTERVENTION AND OUTCOME MEASURE: 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. RESULTS: Approximately three-quarters of the adults with implants experienced vertigo or imbalance. Vestibular therapy was beneficial in alleviating these symptoms. CONCLUSION: A significant number of patients experienced vertigo after cochlear implant surgery. Vestibular therapy is a successful treatment of condition.

Treatment of tinnitus with electrical stimulation.

The purpose of this study was to evaluate the treatment of tinnitus with electrical stimulation. Five hundred patients with tinnitus were treated with probe electrical stimulation. Causes of tinnitus were sensorineural hearing loss (303 patients), Meniere's disease (88), infection (25), head trauma (39), acoustic trauma (25), ototoxicity (4), and chemotherapy (2). Treatment involved 6 to 10 transcutaneous treatment electrical stimulation sessions biweekly. Fifty-three percent of patients showed decreases in their tinnitus as measured by a subjective rating scale. With a 3-month follow-up, 72% had no loss of benefit. Thirteen patients had temporary increases in their tinnitus. Two patients had permanent increases. Probe electrical stimulation seems to offer some benefit in about half the patients treated for annoying tinnitus.

Comparison of the canalith repositioning procedure and vestibular habituation training in forty patients with benign paroxysmal positional vertigo.

Forty patients with benign paroxysmal positional vertigo were treated with either the canalith repositioning procedure or vestibular habituation exercises to determine which treatment approach would be most effective. Twenty additional patients with benign paroxysmal positional vertigo were not treated and served as a control group. The intensity and duration of symptoms were monitored during a 3-month period. All patients had symptomatic relief in the treated groups. The canalith repositioning procedure seemed to give resolution of symptoms with fewer treatments, but long-term results show either treatment approach is effective in relieving positional vertigo. A significant number of patients in the control group (75%) continued to have vertigo. Advantages and disadvantages of the canalith repositioning procedure and vestibular habituation exercises are discussed.
