OBJECTIVE: The purpose of this study was to investigate properties of tinnitus which starts after cochlear implantation. Of the 17 adult patients in our cochlear implant group, four (23.5%) who had no pre-implantation tinnitus were eligible for the study. METHODS: Each patient was requested to complete a short questionnaire regarding his or her experience with tinnitus. Tinnitus match test was performed for each patient by using an Interacoustic Clinical Audiometer (model AC40; Assens, Denmark). RESULTS: Tinnitus match test revealed a tinnitus frequency of a 4KHz for three and of a 6KHz for one patient. Mean value of the loudness score was calculated as 17.5dB SL. CONCLUSIONS: The results of this study emphasize the importance of counseling patients regarding risks of tinnitus after cochlear implantation.
