概括

第一个耳植入器 (CI) 耳中的听力保存不能预测第二只耳中的结果. 在第二种植入的耳朵中发生了更大的听力损失,这表明手术因素显著影响听力保护.

科学领域:

耳鼻喉科耳鼻喉科耳鼻喉科
神经外科神经外科
听力学听力学是指听力学.

背景情况:

顺序双侧耳植入 (CI) 是一个常见的程序,对于有听力损失的成年人.
了解两个耳朵的听力保护 (HP) 对于优化患者的治疗结果至关重要.
根据第一个耳朵预测第二个植入耳朵的HP是可取的,但尚未确立.

研究的目的:

为了比较第一个和第二个植入耳朵之间的听力保护 (HP) 结果在成年顺序双边CI接受者中.
为了确定影响双边CI使用者的耳朵之间的HP变异性的因素.

主要方法:

在第三级推CI中心进行了一项回顾性队列研究.
60名患有术前功能性听力的成年患者用相同的电极阵列进行了连续的双边CI.
通过比较低频纯色平均 (LFPTA) 在植入后1个月和12个月的变化来评估听力保护.

主要成果:

第一个和第二个植入耳朵的LFPTA转移之间的相关性在1个月和12个月时是弱的和无意义的.
一个多层模型显示,第二种植入耳朵的LFPTA转移 (平均差异:6.3dB HL) 比第一种植入耳朵要大得多.
听力保护在12个月内下降,年轻患者随着时间的推移经历了更大的转变.

结论:

第一个植入耳朵的听力保存是第二个植入耳朵结果的糟糕预测.
显著的耳间HP变异性表明手术技术和插入动态比患者特定因素发挥更大的作用.

关键词:

年龄年龄年龄年龄年龄年龄电声刺激是一种电声刺激.电极阵列是一个电极阵列.听力损失听力损失低频纯色调的平均值是低频的.

Auditory Perception

Auditory Perception

The auditory system is essential for sound perception, utilizing various critical structures. When sound waves enter the outer ear, they travel through the ear canal and cause the eardrum to vibrate. These vibrations are then transmitted to the middle ear, where three tiny bones – the malleus, incus, and stapes – amplify the sound. This amplification is crucial, as it ensures that the sound vibrations are strong enough to be conveyed to the inner ear. These vibrations then reach the cochlea, a...
