The Cochlea01:13

The Cochlea

44.0K
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.

科学领域:

  • 耳鼻喉科 耳鼻喉科 耳鼻喉科
  • 神经外科 神经外科
  • 生物医学工程 生物医学工程

背景情况:

  • 耳植入是严重到严重的感觉神经神经听力损失的关键治疗方法.
  • 围膜和侧壁电极阵列之间的选择是一个关键的外科决定.
  • 了解阵列类型和位置对听力结果的影响至关重要.

研究的目的:

  • 根据电极阵列类型 (周边边与侧面壁) 对比成年耳植入体接受者的语音感知和前庭结果.
  • 为了研究最终电极阵列位置和听觉表现之间的关系.

主要方法:

  • 一项前性随机受控研究,涉及144名患有严重至严重听力损失的成年参与者.
  • 随机化以接收周边或侧面壁电极阵列.
  • 通过圆束计算机断层扫描对电极阵列位置的评估,手术前后的语音感知,以及前庭症状.

主要成果:

  • 对两种阵列类型的植入后3个月和12个月观察到显著的语音感知改善.
  • 在3个月或12个月后,在周边壁电极阵列和侧面壁电极阵列之间没有发现语音感知得分的显著差异.
  • 电极阵列位置在 tympani 杆内与语音感知结果没有相关,并且在两组之间没有注意到前庭症状的显著差异.

结论:

  • 周边和侧面壁电极阵列,当正确地放置在 tympani,导致优秀的语音感知结果.
  • 电极阵列类型的选择似乎没有显著影响成年耳植入体用户的语音感知或前庭功能.
