Abstract: 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 changes of cVEMP may be observed after CI. One is negative response and the other is impairment, which reflects surgical injury to saccule 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.
