Abstract

OBJECTIVE : To study and compare the objective benefits of VIBRANT SOUNDBRIDGE VSB in patients with mixed and conductive hearing loss by disease category. METHODS : Two different groups were evaluated : 1 twenty cases of middle ear disease and 2 three patients with congenital aural atresia. Preoperative and postoperative aided and unaided free field audiometry and speech recognition in quiet and noise were used to assess the hearing outcome. RESULTS : There was no change in residual hearing before and after surgery. Average functional gain including speech range from 1000 Hz to 4000 Hz was 35 dB in the middle ear disease group, and 50 dB in the congenital aural atresia group. The speech recognition score under quiet and noisy conditions improved significantly in both groups. Reoperations were performed to correct the gap between the FMT and round window membrane in two cases in the middle ear disease group. Conclusion : VSB operation with a round window vibroplasty is a safe and effective procedure for any disease with mixed and conductive hearing loss.
