多导人工耳蜗的临床应用(附11例报告)

目的：探讨多导人工耳蜗植入对深度感音神经性耳聋患者的治疗效果。方法：对11例深度耳聋患者行MiniSystem22导和Nucleus24导人工耳蜗植入术，其中语前聋6例，语后聋5例。术后1～1．5个月开机调试。结果：11例患者全部恢复了听力；语后聋患者不需要经过唇读或简单的语言训练就能进行对话和打电话，患者能回到有声世界进行正常的生活和工作；对语前聋患者进行评议训练，都有不同程度的进步。结论：深度感音神经性耳聋患者植入22导及24导人工耳蜗后效果良好，尤其对语后聋和年龄较小的儿童效果更好。

The clinic application of multichannel cochlear implant with eleven cases reported

Objective:To review the effects of profound sensorineural deaf patients who were implanted mul-tichannel cochlear.
