摘　　要：目的:对比人工耳蜗植入术后听功能评估中电诱发听觉脑干反应(EABR)及电诱发复合动作电位(ECAP)的作用。方法:对53例Nucleus24R型人工耳蜗植入者行第10电极EABR及ECAP测试。EABR测试参数:刺激频率48Hz,脉宽25μs/相。ECAP测试参数:脉宽25μs/相,刺激频率900Hz。比较EABR和ECAP波形出现率。结果:EABR波形出现率为96.22%,高于ECAP波形出现率(88.68%,χ2=61.3,P<0.05)。结论:EABR是对人工耳蜗植入者听功能进行客观评价的有效方法,在对人工耳蜗术后听功能评价方面优于ECAP测试。Aim ： To compare the effects of electrically evoked auditory brainstem response （EABR） test and electrically evoked compound-action potential （ECAP） test in evaluating postoperative auditory system function of cochlear implant patients. Methods：EABR and ECAP at the 10th electrode were recorded in 53 cases that received Nucleus 24 cochlear implant. The parameters of EABR test were： frequency： 48 Hz,pulse wide： 25 μs/phase. The parameters of ECAP test were： pulse wide： 25 μs/phase, frequency： 900 Hz. The rates of elicited EABR and ECAP waves were compared. Results： EABR waves was elicited in 96.22% cases, which was higher than that of ECAP （88.68% , χ^2 = 61.3, P 〈 0.05 ）. Conclusion ： EABR test is an effective method of evaluating auditory system function and is superior to ECAP test.
