To determine the long-term benefit of the Vibrant Soundbridge (VSB) middle ear implant in patients with severe mixed hearing loss and to compare it with other hearing devices.
A retrospective analysis.
University-affiliated medical center.
Six patients with severe mixed hearing loss and a mean sensorineural hearing loss component between 40 and 70 dB.
Patients received a VSB with the floating mass transducer (FMT) coupled to the round window or to the oval window via a residual stapes structure.
Functional gain and speech recognition results. Results are compared with 2 control groups matched for mean sensorineural hearing loss: 1) patients with mixed hearing loss and a bone-anchored hearing device, and 2) patients with sensorineural hearing loss and traditional implantation of the VSB.
There is large variance in functional gain between the patients suggesting high variability in the effectivity of the FMT coupling. The speech recognition results for the experimental group were not systematically better than in either control group.
There is large variability in results that might be ascribed to coupling effectivity. On the average, speech recognition results were not better or worse than those found in patients with similar hearing loss fitted with bone-anchored hearing devices.
确定 Vibrant Soundbridge（VSB）中耳植入物对重度混合性听力损失患者的长期益处，并将其与其他听力设备进行比较。
回顾性分析。
大学附属医院。
6 名患有严重混合性听力损失且平均感音神经性听力损失成分在 40 至 70dB 之间的患者。
患者接受了带有浮动质量换能器（FMT）的 VSB 治疗，该换能器通过残余镫骨结构连接到圆窗或卵圆窗。
功能增益和语音识别结果。将结果与 2 个平均感音神经性听力损失匹配的对照组进行比较：1）混合性听力损失和骨锚式听力设备的患者，以及 2）感音神经性听力损失和传统 VSB 植入的患者。
患者之间的功能增益差异很大，表明 FMT 耦合的有效性存在很大差异。实验组的语音识别结果并不比任何对照组都好。
结果存在很大的差异，这可能归因于耦合的有效性。平均而言，语音识别结果与佩戴类似听力损失的骨锚式听力设备的患者没有更好或更差。
