Abstract
A 68-year-old woman who had bilateral mixed hearing loss with right cholesteatoma and left tympanosclerosis underwent a round window vibroplasty of middle ear implant, Vibrant Soundbridge (VSB) and the results were compared with hearing aid. She underwent tymapanoplasties for the right cholesteatoma at her age of 55, 66 and 67 years. She had started wearing hearing aid on her left ear since age 57. The hearing aid evaluation test revealed that the effect of hearing aid has not been satisfactry. Maximum speech discrimination score in the right was much poor compared with that in the left ear. We performed the round window vibroplasty with VSB for her left ear and tried to use the RW-couple because of otosclerosis of round window.
Speech discrimination scores in quiet and noisy environment, functional gain, and questionnaire with APHAB test (except for aversiveness Scale) in the VSB were better than those in the conventional hearing aid after VSB fitting in the audio processor for 1 month.
