概括

在耳植入物 (CI) 手术后,较低的神经响应值 (NRT) 和更广泛的动态范围 (DR) 预测了更好的语音感知. 这些CI映射变量是听觉结果的关键预后因素.

科学领域:

听力学听力学是指听力学.
神经外科神经外科
生物医学工程生物医学工程

背景情况:

耳植入物 (CI) 对于后语言失聪的成年人来说至关重要.
优化CI编程 (映射) 对于有效的康复至关重要.
动态范围 (DR) 和神经响应值 (NRT) 是关键的映射参数.

研究的目的:

分析动态范围 (DR) 和神经响应值 (NRT) 在CI后的变化.
为了确定DR和NRT是否预测语音感知结果.
为了确定CI成功的预后因素.

主要方法:

对33名成年语后CI使用者的回顾性分析 (Cochlear Nucleus).
在植入后的1,3,6个月和12个月评估语音感知.
测试包括辅助听力测量和各种语音测试 (辅音,母音,单词,句子).

主要成果:

在CI后的第一年观察到DR的逐渐增加.
显著的DR增加发生在3,6和12个月 (p<0.05到p<0.001).
在12个月后,在所有语音感知结果中都取得了显著的收益 (p<0.001).

结论:

较低的初始NRT和更宽的最终DR与更好的语音感知结果相关.
DR和NRT作为CI语音感知的有价值的预后指标.
优化基于NRT和DR的CI映射可以改善患者的治疗结果.

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.
