多频稳态诱发电位与听性脑干反应对成人感音神经性耳聋听阈的评估比较

Comparison of the audiometric assessment on patients with sensorineural hearing loss by auditory steadystate responses and by auditory brainstem responses

目的:比较多频稳态诱发电位(ASSR)与短声听性脑干反应(ABR)对成人感音神经性聋患者听阈的评估。方法:对102例成人感音神经性聋患者分别测试ASSR反应阈、ABR反应阈和纯音测听,比较ASSR反应阈和ABR反应阈与纯音听阈的相关性,从而评估二者对行为听阈预测的准确性。结果:ASSR反应阈、ABR反应阈和行为听阈之间均有较高的相关性。二者在高频与行为听阈相关性较接近。但在低频,ASSR的相关性较ABR高。结论:ASSR和ABR均可用作感音神经性聋患者客观听阈的评估,但ASSR较ABR有更大的优势。

Objective To compare the accuracy of threshold estimation tested by multiple auditory steady state responses （ASSR） and by auditory brainstem responses （ABR） in adults with sensorineural hearing loss （SNHL）. Methods 102 patients （158 ears） with varying degrees of SNHL were included and received pure-tone audiometry, multi-channel ASSR, and ABR tests for threshold measurement. The correlation of pure tone thresholds with ASSR and ABR thresholds were assessed. Results Both ASSR and ABR had high correlations with behavioral thresholds in all subjects. The two methods had similar accuracy to estimate behavioral thresholds at high frequency ; ASSR had higher accuracy than ABR had in estimating behavioral thresholds at low frequency. Conclusion Both ASSR and ABR could be used to estimate behavioral thresholds in adults with SNHL, but ASSR had more predominance than ABR in estimating behavioral thresholds.
