摘　　要：目的探讨多频听性稳态反应(MASSR)评估听力正常青年人骨导纯音听阈的可能性,旨在观察听力正常青年人骨导多频听觉稳态反应(ASSR)测试的正常值特点,进一步探讨骨导ASSR的反应阈与骨导纯音听阈的相关性,为临床上对不能配合做纯音测听的患者行听力评估时提供客观参考。方法对20例(男10例、女10例)听力正常青年人进行骨导ASSR及骨导纯音听阈检查,记录0.5、1.0、2.0、4.0kHz反应阈及行为听阈,比较二者间的相关性。结果骨导ASSR反应阈男组、女组间差异无统计学意义;各频率间骨导ASSR反应阈比较,4.0kHz较其它各频率差异有统计学意义(P<0.001),0.5、1.0、2.0kHz三个频率间差异无统计学意义(P>0.05)。骨导ASSR反应阈与骨导纯音听阈在0.5、1.0、2.0、4.0kHz四个频率处相关系数分别为0.95、0.91、0.26、0.29。结论骨导ASSR反应阈与骨导纯音听阈间只有在0.5、1.0kHz时有较好的相关性,高频的骨导ASSR与骨导纯音听阈差异性比较大,因此目前还不能广泛用于临床评估高频骨导纯音听阈。Objective To explore the prediction of bone-conduction of audiometric （BC-A） threshold in normal-hearing adults using multiple auditory steady-state response（ASSR）. Methods BC-ASSR and BC-A were recorded in 20 nor- mal-hearing adults（ 10 males and 10 females）. The response thresholds and the behavioral thresholds were compared at 0.5, 1. O, 2.0 and 4.0 kHz to get the correlation and regression formulae. Results There were no significant differ- ences between the men and women for the response thresholds. There was a significant difference at 4 kHz for BC-AS- SR. At the other three frequencies, no significant differences were found. Pearson correlation coefficients between the response thresholds and the behavioral thresholds were 0.95, 0.91, 0.26 and 0.29 at 0.5, 1.0, 2.0 and 4.0 kHz. Conclusion BC-ASSR can only be used to predict the BC-A at 0.5 and 1.0 kHz. The correlation between the response thresholds of BC-ASSR and BC-A is not strong.
