概括

电气唤起的复合作用电位 (ECAP) 值可以预测小儿耳植入物使用者的舒适的声音水平,在没有 stapedial反射值 (ESRT) 的情况下提供替代方案.

科学领域:

听力学听力学是指听力学.
生物医学工程生物医学工程
儿科医学儿科医学

背景情况:

在耳植入物使用者中,ECAP和ESRT之间存在不同的相关性.
在年轻的儿科耳植入体接受者中,ECAP/ESRT关系的数据有限.

研究的目的:

在小儿耳植入物使用者中比较ECAP和ESRT测量.
在基于ESRT的地图中确定ECAP值的位置.
评估ECAP作为用于耳植入物编程的替代措施.

主要方法:

40名儿童 (3-6岁) 使用单侧MedEL耳植入器.
在所有电极上测量ECAP和ESRT值,激活后3个月.
在单个映射会话中同时测量.

主要成果:

在ECAP和ESRT值之间发现了显著的差异.
在ECAP和ESRT值之间观察到中等,显著的相关性.
ECAP值预测了基于ESRT的MCL,并且在上部刺激水平以下下降了17-34%.

结论:

ECAP值是ESRT的一个可行的替代方案,用于编程儿科耳植入物.
基于ECAP的估计可以近似ESRT衍生的MCLs.
为不合作的儿科患者或当ESRT无法获得时,确保适当的刺激.

关键词:

耳植入物可以使用耳植入物.动态范围动态范围在ECAP中,我们可以使用ECAP.这是ESRT ESRT.在 MCL 和 MCL 之间.

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.
