摘要
目的 通过检测13例听神经病患者的前庭诱发的肌源性电位(vestibular evokedmyogenic potentials,VEMPs),了解听神经病患者是否同时伴发前庭下神经损害,探讨前庭下神经损害与听神经病的关系。方法 记录13例听神经病患者VEMPs,观察VEMPs表现形式;分析病程、低频听阈及言语识别率与VEMPs的关系。结果 13例听神经病患者中有7例存在VEMPs异常,占54％。异常的表现形式为VEMPs低振幅和VEMPs不能引出。正常VEMPs与异常VEMPs在低频听力损失、病程和言语识别率3个方面差异无显著性(P>0.05)。结论 部分听神经病患者伴发前庭下神经功能异常,说明两者病变可以同时并存;听神经病患者的病变程度方面与VEMPs无明显直接相关性,说明听神经病与前庭下神经损害两者之间又具有相对独立性。
Objective To investigate if auditory neuropathy have inferior vestibular nerve (IVN) lesion and to explore the relation between AN and the IVN lesion by vestibular evoked myogenic potentials (VEMPs). Methods VEMPs were observed in 13 patients with auditory neuropathy. And the relation among the duration, hearing threshold of lower frequency and speech discrimination score with VEMPs were observed. Results Fifty-four percent patients in auditory neuropathy had abnormal VEMPs. They took the form of lower amplitude and no response. The statistical analysis showed that the abnormality of VEMPs had no correlation with lower frequency hearing loss, the duration and speech discrimination score. Conclusions The IVN dysfunction may coexist with auditory neuropathy, having lesion in the IVN. However,there was no significant relation between the severity of AN and VEMPs, which meant that AN and inferior vestibular neuropathy had their independence to some extent.
