Abstract
in English, Chinese

Some patients with severe-profound sensorineural hearing loss （SNHL） with normal cochlear anatomical structure received cochlear implantation （CI） and the hearing and speech rehabilitation effect was not ideal. Through retrospective analysis, it was found that some of these patients had cochlear never canal （CNC） stenosis, or atresia in severe cases.This article reviews the development of the CNC, the diagnostic criteria of CNC stenosis and the results of hearing and speech rehabilitation in these patients after CI.

摘要: 既往部分耳蜗解剖结构正常的重度或极重度感音神经性聋患者接受人工耳蜗植入术后听觉、言语康复效果不理想，通过回顾性研究分析，发现这类患者中部分存在蜗神经管狭窄，严重者表现为闭锁。本文对蜗神经管的发育、蜗神经管狭窄的判断标准及此类患者接受人工耳蜗植入术后听觉、言语康复效果的最新研究成果予以综述。.

Keywords: auditory and speech rehabilitation; cochlear never canal stenosis; hearing loss, sensorineural.
