前庭诱发肌源性电位在梅尼埃病诊断中的意义

Significance of Vestibular Evoked Myogenic Potential in Diagnosis of Meniere's Disease

目的:探讨前庭诱发肌源性电位(VEMP)检查在梅尼埃病诊治中的意义。方法:梅尼埃病患者行纯音测听、前庭冷热水试验和VEMP检查。结果:正常双侧短声刺激p13波和n23波出现率为100%,梅尼埃病患者VEMP30%不能正常引出,有3种表现形式:VEMP患侧无反应、患侧反应振幅正常和VEMP患侧反应低振幅。结论:梅尼埃病的诊断仍以临床症状为基础,结合前庭冷热水试验和VEMP检查,可达到早期诊断、提高确诊率的目的。

Objective To investigate the significance of Vestibule evoked myogenic potentials in diagnosis of Meniere＇s disease,Methods Patients with Meniere＇s disease were given pure tone hearing threshold test,vestibular bithermal caloric test and vestibular evoked myogenic potentials （VEMP）test.Results The wave of p^13 and n^23 appeared 100% in normal subjects,but disappeared 30% in Meniere＇s disease. There were 3 kinds of manifestation of VEMP ：normal response, no response and lower amplitude in disease side.Conclusion Diagnosis of Meniere＇s disease is mainly based on the medical history.If it could combine with vestibular bithermal caloric test and VEMP ,the diagnosis would be earlier and more accurate.
