摘　　要：目的探讨在感音神经性听障患儿佩戴助听器后声场短纯音刺激听觉皮层诱发电位(cortical auditory evoked potential,CAEP)反应阈与助听后行为测听阈值在0.5、1、2、和4 kHz的相关性,为快速在清醒状态下客观评估助听器效果提供参考。方法选取2023年1月1日至2023年10月15日于惠耳国际听力中心前来复查的轻至重度感音神经性听损的助听器验配的患儿27例(27耳),轻至重度感音神经性听障儿童,在测试频率0.5、1、2、和4 kHz使用声场短纯音引出助听后CAEP的P1波反应阈及对应声场行为测听阈值,并进行同体对比分析各频率相关性。结果儿童的声场下短纯音CAEP P1反应阈及声场行为测听的助听听阈在0.5、1、2、4 kHz测试频率显著相关,r系数依次为0.825、0.766、0.583及0.610;在各测试频率上助听后声场CAEP和语频纯音平均阈值差依次为(6.30±8.27)、(3.52±8.86)、(2.41±9.84)、(1.67±10.83)dB HL。结论感音神经性耳聋儿童佩戴助听器的声场短纯音CAEP P1波反应阈值与声场行为测听阈值显著相关、差值小,声场CAEP可用于听障患儿进行助听后清醒状态下的客观效果评估,提高临床工作效率。Objective To discover the correlation of aided tone burst cortical auditory evoked potentials(CAEP)responsive thresholds with aided behavioral audiometry thresholds at 0.5、1,2 and 4 kHz in children with sensorineural hearing loss after hearing aid intervention,to provide rapid objective evaluation in awake state as reference for hearing aid fitting.Methods Our study recruited 27 children(27 ears)with mild to profound sensorineural hearing loss(SNHL)who visited Huier Hearing Clinic between 1st January 2023 to 15th October 2023 and the aided CAEP P1 responsive thresholds and aided behavioral thresholds at frequencies 0.5,1,2 and 4 kHz were collected for correlation analysis.Results There were strong correlation between free-field CAEP P1 thresholds and free-field aided behavioral thresholds in children across 0.5,1,2 and 4 kHz(r for hearing aid interventions=0.825,0.766,0.583 and 0.610,respectively).At the tested frequencies,the difference between aided thresholds for hearing aid intervention was(6.30±8.27),(3.52±8.86),(2.41±9.84),(1.67±10.83)dB HL respectively.Conclusion With hearing aid intervention,aided free-field CAEP P1 responsive thresholds and aided behavioral thresholds demonstrated significant correlation with small differences in children with SNHL.Thus CAEP is capable in providing objective insights upon hearing aid fitting in awake children,increasing clinical testing efficiency.
