概括
对于带有周边节电极的单侧耳聋患者来说,将基底电极靠近修饰器的位置显著改善了语音感知,而不是频率不匹配. 这凸显了电极放置对于更好的结果的重要性.
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:
- 单侧耳聋 (SSD) 对语音感知提出了重大挑战.
- 在SSD的耳植入中使用周边节电极 (PMEs).
- 优化语音结果需要了解影响PME表现的因素.
研究的目的:
- 评估频率不匹配和电极接近对PMEs的SSD患者语音感知的影响.
- 要确定哪个因素,频率不匹配或电极定位,是语音结果的更强有力的预测因素.
- 评估这些关联是否随着时间的推移而变化.
主要方法:
- 对34名患有PMEs的SSD患者的回顾性分析.
- 频率不匹配的计算使用斯塔霍夫斯卡亚螺旋团图.
- 通过手术后的CT扫描测量电极距离模块的距离.
- 使用辅音 - 核心 - 辅音语音 (CNCP) 评分和3个月和12个月的语音噪音测试来评估语音感知.
主要成果:
- 从手术前的水平,CNCP得分从手术前的水平显著提高到12个月后的58%.
- 较接近基底电极的近距离与modiolus显示最强的相关性与改善的CNCP得分.
- 频率不匹配也与CNCP相关,但基底不匹配是12个月的唯一显著预测因素.
- 频率不匹配和电极接近是相互关联的,这表明定位是主要的驱动因素.

01:13The Cochlea
51.7K
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.

The human brain perceives pitch through two primary mechanisms reflected in place theory and frequency theory. Each mechanism describes how sound waves are interpreted as specific pitches by the brain, offering insights into the intricate processes of auditory perception.
Place theory, or place coding, suggests that different pitches are heard because various sound waves activate specific locations along the cochlea's basilar membrane. The brain determines the pitch of a sound by...
