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: To understand the characteristics of the electrocochleogram in patients with auditory neuropathy. Methods: The auditory neuropathy group and normal control group were recorded by external auditory meatus silver ball electrodes, and the difference of -SP amplitude between the two groups was recorded. Results: The frequency of SP wave in patients with auditory neuropathy was 100%, and the amplitude was significantly different from the normal control group (P <0.01). AP amplitude is small, but the export rate as high as 84%. CONCLUSIONS: Patients with auditory neuropathy have -SPs that can elicit and increase in amplitude.
