This study aimed to review current knowledge regarding implantation of the Vibrant Soundbridge floating mass transducer (FMT) at the round window (round window vibroplasty) as well as to form a consensus on steps for a reliable, stable surgical procedure.
Review of the literature and experimental observations by the authors.
Round window (RW) vibroplasty has been established as a reliable procedure that produces good and stable results for patients with conductive or mixed hearing loss. The experience gained over the past few years of the authors' more than 200 implantations has led to consensus on several key points: (1) a wide and bloodless access to the middle ear with facial nerve monitoring, (2) the careful and correct identification and exposure of the round window membrane, (3) a good setup for efficient energy transition of the FMT, namely, perpendicular placement of the FMT with no contact to bone and the placement of cartilage behind the FMT to create a preloaded "spring" function, and (4) 4 points of FMT fixation: a rim of the round window bony overhang left intact both anterior and posterior to the FMT, conductor link stabilization, and cartilage behind the FMT. In addition, the FMT should be covered with soft tissue.
本研究旨在回顾关于在圆窗植入振动声桥浮动质量传感器（FMT）（圆窗振动成形术）的现有知识，并就可靠、稳定的手术步骤达成共识。
作者对文献的回顾及实验观察。
圆窗振动成形术已被确立为一种可靠的手术方法，对于传导性或混合性听力损失患者能产生良好且稳定的效果。作者在过去几年200多次植入手术中积累的经验，在几个关键点上达成了共识：（1）在面神经监测下，广泛且无血地进入中耳；（2）仔细且正确地识别和暴露圆窗膜；（3）为FMT的高效能量转换做好良好设置，即FMT垂直放置且不接触骨质，并在FMT后方放置软骨以形成预加载的“弹簧”功能；（4）FMT的四点固定：在FMT前后保持圆窗骨悬突边缘完整、稳定传导连接以及在FMT后方放置软骨。此外，FMT应用软组织覆盖。
