概括
耳硬化手术可以暂时减少骨传导,大多数患者恢复听力. 诸如年龄和最初的骨传导水平等因素影响恢复,而早期的高频损失预测永久性听力损失.
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.
- 外科手术的结果
背景情况:
- 耳硬化手术带有手术创伤的风险,导致骨传导减少.
- 了解骨传导变化后的骨硬化手术对于患者管理至关重要.
研究的目的:
- 为了评估骨硬化手术后的骨传导改变.
- 确定导致术后骨传导能力下降的因素.
主要方法:
- 对109名接受耳硬化手术的患者进行了回顾性分析.
- 纯音调听力测量在手术前和手术后2天,1个月,1年评估.
主要成果:
- 28%的患者在术后第二天经历了>5dB的骨导电减少,9%的患者在1年后表现出持续的损失.
- 永久性骨传导损失的更高风险与早期高频率损失,年龄较大和手术前骨传导值>20dB有关.
- 修复手术并不是骨传导损失的重要因素.
结论:
- 骨髓硬化术后的骨传导率下降通常是短暂的.
- 患者的年龄和手术前的骨传导水平会影响听力恢复.
- 早期术后高频率的骨传导减少是永久性听力损失的负面预测因素.

Hearing
51.8K
When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.

The Cochlea
44.5K
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.
