概括

耳植入物中的Slim Modiolar (SM) 电极载体有助于保持残留听力,特别是在低频段. 虽然短期结果显示部分听力保存,长期随访表明略有下降,但仍然保持大多数患者的残留听力.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
听力学听力学是指听力学.
生物医学工程生物医学工程

背景情况:

耳植入旨在恢复严重或严重听力损失的个体的听力.
保持残留听力是优化耳植入物结果的关键因素.
电极载体的选择可以影响植入后的听力保护.

研究的目的:

为了评估接受用Slim Modiolar (SM) 电极载体进行耳植入的患者的听力保护.
评估SM电极载体在不同时间点对残留听力的影响.

主要方法:

一项回顾性,单心研究包括51名残留听力 (60只耳朵) 的成年患者.
频率特定的纯色声度测试是在手术前,手术后30天内,以及长期随访 (平均20.7个月) 进行的.
使用HEARRING分类系统和低频纯音平均值来分析听力保护.

主要成果:

短期 (手术后30天) 的听力保存平均为70% (部分保存).
长期随访 (平均20.7个月) 显示听力保护下降到61%,仍然被认为是部分的.
在随访期间,在20%的病例中观察到完全听力损失.

结论:

微型模态 (SM) 电极载体有效地促进保留残留听力.
听力保护在SM载体的耳植入后的低频范围内尤其明显.
虽然随着时间的推移会出现一些听力恶化,但SM载体支持持续的残留听力益处.

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.
