BACKGROUND
There is no consensus on treatment of patients with congenital unilateral aural atresia. Currently, 3 intervention options are available, namely, surgical reconstruction, application of a bone-conduction device (BCD), or application of a middle ear implant.
OBJECTIVE
The present study aims to compare the BCD with the application of a middle ear implant. We hypothesized that cross-hearing (stimulating the cochlea by means of bone conduction contralateral to the implanted side) would cause BCD users to have difficulty performing localization tasks.
METHODS
Audiologic data of 4 adult patients with a middle ear implant coupled directly to the cochlea were compared with data of 4 adult patients fitted with an osseointegrated BCD. All patients were fitted during adulthood. The emphasis of this study is on directional hearing.
RESULTS
The middle ear implant and the BCD improved sound localization of patients with congenital unilateral aural atresia. Unaided scores demonstrate a large variation.
CONCLUSION
Our results demonstrate that there was no advantage of the middle ear implant over the BCD for directional hearing in patients who had no amplification in childhood. The BCD users had the best bandwidth.
背景
对于先天性单侧听骨畸形患者的治疗尚无共识。目前有 3 种干预选择，即手术重建、骨导设备（BCD）应用或中耳植入物应用。
目的
本研究旨在比较 BCD 与中耳植入物的应用。我们假设交叉听力（通过对植入侧对侧的骨导刺激耳蜗）会导致 BCD 用户在进行定位任务时遇到困难。
方法
将 4 例直接与耳蜗耦合的中耳植入患者的听力学数据与 4 例佩戴骨整合 BCD 的成年患者的听力学数据进行比较。所有患者均在成年后接受植入。本研究的重点是定向听力。
结果
中耳植入物和 BCD 改善了先天性单侧听骨畸形患者的声音定位。未助听评分显示出很大的差异。
结论
我们的结果表明，对于在儿童时期没有放大的患者，中耳植入物在定向听力方面没有优于 BCD。BCD 用户具有最佳的带宽。
