摘　　要：目的:了解听神经病患者的耳蜗电图特征。方法:用外耳道银球电极记录听神经病组和正常对照组的耳蜗电图,比较两者的-SP波幅差异,统计患耳AP出现的情况。结果:听神经病患者-SP波的引出率为100％,并且其波幅与正常对照组的差异有显著性意义(P<0.01)。AP波幅较小,但引出率高达84％。结论:听神经病患者的-SP可引出且波幅增大。Objective: The purpose of this study was to investigate the ECochG in subjects with auditory neuropathy (AN). Method: The ECochG was recorded from ear canal electrode in patients with auditory neuropathy and normal subjects. The difference of their - SP amplitudes was compared. Result: The - SP was present in all AN ears and its amplitudes were significantly larger than those in normal subjectsC P <0. 01). A low amplitude wave AP was present in 84% AN ears. Conclusion: The -SP was present in all AN ears and its amplitudes were larger.
