Abstract:
Middle ear implantation is indicted for patients who have sensorineural, conductive or mixed hearing loss when conventional surgery or hearing aids do not producde sufficient improvement. This study reports the long-term results of an active middle ear implant, the Vibrant Soundbridge® (VSB) implantation, in a patient with unilateral congenital aural atresia (CAA). VSB was implanted for hearing rehabilitation after failed canaloplasty in a 15-year-old girl. After exposure of deformed ossicle, the floating mass tranceducer was coupled to the stapes head and subsequent subtotal petrosectomy was completed. Preoperative pure-tone air conduction threshold was 68.8 dB, which improved to 15 dB at one year of surgery. The mean aided free field speech discrimination in quiet was 98%. The speech understanding in noise evaluated by the composite score of Hearing-In-Noise test improved from SNR −2.5 dB to −5.2 dB. We present a first report of VSB implantation in a patient with unilateral CAA in Korea. The patient showed a significant hearing gain after the implantation of VSB; moreover, her hearing in noisy environment also showed improvement.
