CONCLUSION
The study suggests that the Vibrant Soundbridge (VSB) middle ear implant could be a valid alternative for patients with congenital aural atresia to compensate for their hearing loss.
OBJECTIVE
To determine the audiologic benefit the VSB provides in patients with congenital aural atresia.
METHODS
Twelve patients with congenital aural atresia were implanted with VSB: eight patients were unilaterally atretic (67%) and 4 (33%) were bilaterally atretic. In five cases the implant was placed onto the round window, in another five cases the implant was placed on the stapes, in only one case a prosthesis (coupler) was used to fix the implant into the oval window, and in one case a fenestration on the cochlear endostium was performed.
RESULTS
The mean functional gain obtained for all patients evaluated was 62 dB at 0.5 kHz, 60 dB at 1 kHz, 48.3 dB at 2 kHz, and 50.8 dB at 4 kHz. The mean functional gain for all frequencies evaluated was 55.1 dB.
结论
该研究表明，活力声桥（VSB）中耳植入物对于先天性耳道闭锁患者而言可能是一种有效的听力损失补偿替代方案。
目的
确定VSB为先天性耳道闭锁患者带来的听力益处。
方法
12例先天性耳道闭锁患者植入了VSB：8例为单侧闭锁（67%），4例（33%）为双侧闭锁。5例将植入物置于圆窗，另外5例置于镫骨上，仅1例使用假体（耦合器）将植入物固定于椭圆窗，还有1例在耳蜗内皮层进行了开窗术。
结果
所有评估患者在0.5 kHz时获得的平均功能增益为62 dB，1 kHz时为60 dB，2 kHz时为48.3 dB，4 kHz时为50.8 dB。所有评估频率的平均功能增益为55.1 dB。
