摘　　要：人工耳蜗是一种声一电转换装置，可将声信号转换为电信号，经植入的电极传人耳蜗，从而产生听觉。目前，人工耳蜗植入（cochlearimplanta-tion，CI）已成为重度极重度感音神经性聋患者最重要的治疗途径。但CI后部分患者出现眩晕及平衡失调等前庭功能紊乱的现象口，Summary Recent studies suggest that changes of cervical vestibular-evoked myogenic potential （cVEMP） could be observed postoperatively, which reflects the degree of damage to saccule caused by cochlear implant （CI）. The waveform of cVEMP can display the influences of surgical methods, ear disease condition, machine status and other factors on saccule, therefore it shows important clinical value in diagnosis and treatment. Two possible chan- ges of cVEMP may be observed after CI. One is negative response and the other is impairment, which reflects sur- gical injury to saccute with varing degree. However, a uniform quantitative conclusion in cVEMP parameters is still expected. By reviewing the studies in cVEMP of CI reciepients, a typical changing pattern was discovered and a more comprehensive understanding about vestibular changes after cochlear implant was achieved.
