婴幼儿Tb-ABR与chirp-ASSR的相关性研究

摘要

目的：分析婴幼儿的Tb-ABR和chirp-ASSR反应阈的相关性和在听力评估中的应用。方法：对听力正常婴幼儿8例和不正常婴幼儿8例进行Tb-ABR和chirp-ASSR反应阈值测试。分别记录0.5、1、2、4 kHz的反应阈，比较这两种不同测试方法所得反应阈的相关性及chirp-ASSR的优点。结果：短纯音ABR与chirp-ASSR反应阈比较差异无统计学意义（P>0.05）。结论：短纯音ABR与chirp-ASSR有较好的相关性，可以有效地用于临床评估。%Objective:To analyze correlation of Tb-ABR and chirp-ASSR response threshold and application in evaluation of hearing in the infant.Method:Tb-ABR and chirp-ASSR were detected in 8 infants of normal hearing infant and 8 infants of abnormal hearing.Then 0.5、1、2、4 kHz response threshold of Tb-ABR and chirp-ASSR were recorded,and the correlation of both were capered and analyzed.Result:There was no significant difference(P>0.05) between tone burst-ABR and chirp–ASSR.Conclusion:Tb-ABR and chirp-ASSR has good correlation,can be effectively used for clinical evaluation.
