| ［摘要］ 目的 探讨短声诱发听性脑干反应阈与不同听力损失构型人群2～4 kHz纯音听阈均值的相关性。方法 听力正常组选择正常听力成人10名（20耳）。62例感音神经性聋患者分为平坦型听力损失24耳及陡降型听力损失38耳。陡降型听力损失组38耳再分为四个亚组：1 kHz陡降型5耳、2 kHz陡降型11耳、4 kHz陡降型19耳、6 kHz陡降型3耳，均采用短声诱发听性脑干反应记录反应阈及纯音测听记录0.25、0.5、1、2、4、6、8 kHz反应阈，记录数据通过SPSS V13.0软件进行分析。结果 听力正常组、平坦型听力损失组、1 kHz陡降型听力损失组、2 kHz陡降型听力损失组2～4 kHz纯音听阈均值及click-ABR的反应阈的直线相关系数分别为0.83(P<0.01)、0.94(P<0.01)、0.97(P<0.01)、0.80(P<0.01)。4 kHz陡降型听力损失组2～4 kHz纯音听阈均值及click-ABR的反应阈的直线相关系数为0.16(P>0.05)，6 kHz陡降组由于病例较少，差异无统计学意义。结论 click-ABR的反应阈与2～4 kHz纯音听阈均值相关性好，但是不能理解为能够用click-ABR的反应阈较精确评估2～4 kHz纯音听阈均值。click-ABR的反应阈与2～4 kHz纯音听阈均值之差的修正值为36 dB,对于正常听力人群和平坦型听力损失人群可较精确评估听阈；对陡降型听力损失人群的听阈评估，ABR的反应阈与2～4 kHz纯音听阈均值之差从10 dB到70dB。尽管如此，在临床应用中click-ABR的反应阈作为听阈评估仍有其参考价值。 |

| ［Abstract］ Objective To explore the correlation of hearing thresholds using click evoked auditory brainstem response(click-ABR) and pure tone audiometry(PTA) with different auditory configurations.Methods Ten normal hearing adults(20 ears). Sixty-two cases of sensorineural hearing loss were divided into flat type group(24 ears) and steep drop type group(38 ears). The steep drop type group was further divided into four subgroups:1 kHz steep drop type group(5 ears),2 kHz steep drop type group(11 ears),4 kHz steep drop type group(19 ears),6 kHz steep drop type group(3 ears). The response threshold of click-ABR and 0.25,0.5,1,2,4,6,8 kHz hearing threshold of PTA were recorded. The recorded data was analyzed by SPSS V13.0.Results The linear correlation of 2-frequency(2,4 kHz) pure-tone threshold average and the click-ABR response threshold at normal hearing group,flat type group,1 kHz steep drop type,2 kHz steep drop type coefficients were:0.83 (P<0.01),0.94 (P<0.01),0.97(P<0.01),0.80(P<0.01). 4 kHz steep drop type was:0.16(P>0.05). Because of the 6 kHz steep drop group was fewer, it was no statistically significant.Conclusion The response threshold of click-ABR correlated with 2-frequency(2,4 kHz) pure-tone threshold average, but can not be understood to be able to use the response threshold of click-ABR accurate to assess 2-frequency(2,4 kHz) pure-tone threshold average. The correction value of the difference between the response threshold of click-ABR and 2-frequency(2,4 kHz) pure-tone threshold average was 36 dB.For the normal hearing group and the flat-type group,it can be accurate assessment of hearing threshold.For hearing threshold assessment of the steep drop type group，the difference between the response threshold of click-ABR and 2-frequency(2,4 kHz) pure-tone threshold average were from 10 dB to 70 dB. Nevertheless, the response threshold of click-ABR as the hearing threshold assessment still has its reference value in the clinical application. |
