摘要: 目的 通过比较听力障碍者的颅顶慢反应(slow vertex response,SVR)阈值与纯音测听(pure tone audiometry,PTA)阈值的关系,探讨SVR检测技术在法医学听觉功能障碍鉴定中的应用价值。 方法 对25名感音神经性听力障碍者(40耳)分别进行PTA及SVR测试,根据PTA阈值分成轻度、中度及重度听力障碍组,然后用秩和检验对各组的SVR阈值及PTA阈值比较,并对SVR阈值与PTA阈值进行相关分析,拟出根据受试者SVR阈值推导受试者行为听阈的线性回归方程。 结果 在各个检测频率,SVR阈值与PTA阈值均高度相关。并可拟出一元线性回归方程,其相关系数(r)在0.5、1、2和4 kHz分别为0.971、0.976、0.957和0.928(P<0.05)。回代检验结果表明,应用一元线性回归方程评估听力有望成为一个简单可行的方法。 结论 根据建立的应用SVR阈值推断行为听阈的线性回归方程可以较准确地评估受试者的行为听阈。

Abstract: Objective To study the value of slow vertex response(SVR) in the evaluation of hearing loss by comparing the hearing thresholds acquired with SVR and pure tone audiometry(PTA). Methods Twenty-five subjects(40 ears) with sensorineural hearing loss were tested by PTA and SVR. According to the thresholds of PTA, these ears were subdivided into mild, moderate and severe hearing loss groups, and rank sum test was performed on the thresholds of SVR and PTA for all the hearing loss groups. Then, the correlation between PTA thresholds and SVR thresholds was analyzed and the mathematical models were established for predicting behavioral thresholds by the thresholds of SVR. Results At four test frequencies(0.5, 1, 2 and 4 kHz), the thresholds of SVR had high correlations with thresholds of PTA. Four liner regression equations were established, and the correlation coefficient(r) were 0.971, 0.976, 0.957 and 0.928, respectively(P<0.05). Back substitution test showed that the liner regression equations would be an easy method for estimating the behavior thresholds. Conclusion The behavioral threshold can be well judged and evaluated by the liner regression equations established with SVR thresholds.
