听觉脑干电反应可有效预测听力损失患儿的行为听阈

Auditory brainstem response may predict behavior threshold of children with hearing loss

目的探讨幼儿听力损失程度对听觉脑干电反应(ABR)预测行为听阈(BT)的影响。方法选取2012年1月至2016年1月在延安大学附属医院接受听觉脑干电反应和行为听阈测试的179例不同听力损失程度的患儿(共311只耳)作为研究对象,分别对179例患儿进行听觉脑干电反应测试和行为听阈测试,分析听觉脑干电反应与行为听阈相关性,分析ABR阈值与行为阈差值与ABR阈值的影响因素及校正因子以及相关线性回归方程。结果不同频率刺激下,ABR阈值与行为听阈均呈正相关(P<0.05);不同刺激频率下ABR阈值均可预测行为听阈;ABR阈值预测行为阈差值的误差与听力损失程度相关(P<0.05),通过校正可以减少预测误差。结论听觉脑干电反应可以有效预测听力损失患儿的行为听阈,听力损失程度影响听觉脑干电反应与行为听阈间的差异,恒定的修正系数有利于听觉脑干电反应预测行为听阈的精确性。

Objective To investigate the impact of degree of hearing loss on auditory brainstem response predictions of behavioral thresholds.Methods A total of 179 patients with different hearing loss degree(a total of 311 ears)patients from January 2012 to January 2016 in the affiliated hospital of Yan an university were treated with auditory brainstem response(ABR),performed threshold behavior test,analyed the auditory brainstem electric response and behavioral threshold correlation,the factors that affect the ABR thresholds and behavioral threshold value and threshold of ABR and correction factor as well as linear regression equation for different frequency stimulation.Results ABR threshold was positively related to threshold behavior for the different frequencies stimulation,ABR threshold may predicte threshold behavior(P<0.05);ABR threshold value can predicte behavioral threshold difference error and the degree of hearing loss(P<0.05),through the relevant correction factors can reduce the prediction error.Conclusions Auditory brainstem responses may effectively predicte the hearing loss in children with behavioural thresholds,differences in degree of hearing loss influence auditory brainstem response and behavioral threshold value,constant correction coefficient is conducive to auditory brainstem electric response and facilitates accuracy of the behavior threshold.
