Abstract Usage of the Vibrant Soundbridge (VSB) with round window (RW)-Coupler placement at the RW has been shown to successfully treat mixed hearing loss. Coupling between the VSB's floating mass transducer (FMT) and the RW membrane is difficult in the case of sclerosis in the RW and drilling down the bony lip until the RW membrane can be seen completely can possibly induce a perilymphatic fistula. A 68-year-old woman who had bilateral mixed hearing loss with sclerosis in the RW due to tympanosclerosis underwent a RW-Vibroplasty with a RW-Coupler. Speech discrimination scores in quiet and noise and functional gain with the VSB with RW-Coupler were better than those using a conventional hearing aid. The results of the present case have shown the feasibility of implanting a VSB with RW-Coupler in patients with mixed hearing loss due to tympanosclerosis.
摘要 已证明，将振动声桥（VSB）的圆窗（RW）耦合器放置在RW处可成功治疗混合性听力损失。在RW硬化的情况下，VSB的浮动质量换能器（FMT）与RW膜之间的耦合困难，并且钻除骨唇直到可以完全看到RW膜可能会导致外淋巴瘘。一名68岁女性因鼓室硬化症导致双侧混合性听力损失且RW硬化，接受了带有RW耦合器的RW振动成形术。使用带有RW耦合器的VSB时，安静和噪声环境下的言语辨别分数以及功能增益均优于使用传统助听器时的情况。本病例结果表明，在因鼓室硬化症导致混合性听力损失的患者中植入带有RW耦合器的VSB是可行的。
