概括

这项研究确定了Vibrant Soundbridge (VSB) 接受者的手术内听觉脑干响应 (ABR) 值的参考值. 这一新参考文献改善了在VSB手术中对听力损失进行ABR测试的解释.

科学领域:

听力学听力学是指听力学.
神经科学是一个神经科学.
生物医学工程生物医学工程

背景情况:

活力声桥 (Vibrant Soundbridge,简称VSB) 是一种用于听力损失的活跃中耳植入物.
听觉脑干反应 (ABR) 是评估听力值的一种方法.
使用ABR开发了一种用于确定VSB植入物性能的新系统.

研究的目的:

在VSB植入物接受者中建立预期ABR听力值的参考值.
在VSB手术中提高手术内ABR测量的解释性.

主要方法:

在104名因各种听力损失类型而接受VSB手术的患者中记录了ABR.
通过AcoustiAP传输单元向VSB传递一个优化的声刺激.
在患者队列中使用了六种不同的VSB合器.

主要成果:

在手术期间的ABR值始终高于手术前的骨导电 (BC) 值和术后的振动谱测量.
具体来说,ABR值比手术前的BC值高20.1dB.
在6个VSB合器之间没有发现ABR值的显著差异.

结论:

开发的手术内测量参考值有助于解释VSB手术期间的ABR结果.
在使用ABR进行VSB植入物性能评估时,应考虑此参考值.

The Cochlea

The Cochlea

The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.
