title: Tinnitus suppression in cochlear implant patients.
abstract: Tinnitus is sometimes suppressed by cochlear implantation. Tinnitus conditions were examined in 60 adult patients who underwent cochlear implantation in 1990 or later. Before surgery, 90% of these patients reported some type of tinnitus. The patients completed a questionnaire evaluating the loudness and duration of the tinnitus, immediately after the first electrical stimulation and 2 months later. The loudness of tinnitus was suppressed in 65% of the patients at first evaluation. Two months later, the tinnitus was suppressed in 93% of the patients. As for the duration of tinnitus, at first evaluation the tinnitus duration was suppressed in 41% of the patients. Two months later, the duration of tinnitus was suppressed in 61% of the patients.
