摘　　要：目的研究人工耳蜗植入(CI)后声场短纯音听觉皮层诱发电位(CAEP)反应阈与声场行为测听助听听阈相关性,为无法主观配合声场行为测听的CI患者快速高效的评估提供参考依据。方法募集22名(22耳)CI儿童,对同组使用短纯音在0.5、1、2、4 kHz进行声场CAEP P1波反应阈及声场行为测听并进行相关性分析。结果CI后儿童在0.5、1、2、4 kHz声场短纯音CAEP P1反应阈与声场行为测听助听听阈在对应频率的相关性系数r分别为0.567、0.670、0.627及0.762(P<0.05);人工耳蜗声场短纯音CAEP P1反应阈与声场行为测听阈值显著相关,差值在5~8 dB之间。结论声场短纯音CAEP可用于无法主观配合声场行为测听患者的效果评估,对人工耳蜗临床调试工作提供参考依据。OBJECTIVE To study the relationship between frequency specific free-field tone burst cortical auditory evoked potentials(CAEP)and aided behavioral audiometry to provide rapid,reliable insights for predicting hearing intervention efficiency in hard to cooperate cochlear implant patients.METHODS The study comprised of 22 cochlear implant pediatric patients(22 ears)free-field tone burst CAEP P1 response thresholds,free-field behavioral thresholds determined within the group across frequencies 0.5,1,2 and 4 kHz were collected for correlation analysis.RESULTS The free-field tone burst CAEP P1 response thresholds and free-field behavioral audiometric thresholds in cochlear implant pediatric patients for testing frequencies 0.5,1,2,4 kHz were compared and r correlation coefficients found were 0.567,0.670,0.637 and 0.762 across the frequencies respectively(P<0.01).The mean difference between free-field CAEP P1 response threshold and free-field behavioral thresholds for cochlear implant patients differ by 5-8 dB with statistical significance.CONCLUSION Free-field tone burst CAEP can be used for cochlear implant programming validation in patients that fail to cooperate in behavioral testing,thus is applicable in cochlear implant programming clinical practice.
