Tinnitus after cochlear implantation.
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.
