[Evaluation of curative effect of VNG and VEMP in patients with severe sudden hearing loss].

To evaluate the relationship between vestibular function and curative effect in patients with severe sudden hearing loss.The vestibular function of 79 patients with severe hearing loss was examined by video-nystagmography (VNG) and vestibular evoked myogenic potential (VEMP).There were significant differences between the two test outcomes (<0.01) in the severe group (27 cases). The effective rate of both VNG and VEMP normal group was 100%, the effective rate that both VNG and VEMP were abnormal was 41.7%. In the profound severe group (52 cases) there was also a significant difference between the two test results and the therapeutic effect (<0.01). The effective rate of both VNG and VEMP normal group was 76.9%. The effective rate was 34.6% with both VNG and VEMP abnormal. There was no significant difference between hearing loss degree and curative effect.The VNG and VEMP examinations in patients with severe sudden hearing loss are valuable in evaluating the efficacy. Both VNG and VEMP were abnormal with the worst curative effect.
