摘　　要：目的：探讨感音神经性聋耳蜗的功能状态以及耳声发射在诊断感音神经性聋上的应用价值。方法：通过对２０例（４０耳）健康人及７０例（９３耳）感音神经性聋患者畸变产物耳声发射（ｄｉｓｔｏｒｔｉｏｎｐｒｏｄｕｃｔｏｔｏａｃｏｕｓｔｉｃｅｍｉｓｉｏｎ，ＤＰＯＡＥ）的Ｉ／Ｏ曲线的测试和分析。结果：感音神经性聋不同个体测试结果差别较大，与正常耳指标均值相比存在一定数量不规律个体。结论：感音神经性聋患者耳蜗的功能状态不同，对主动机制的影响也不同，因此耳声发射在临床应用上仍有一定的局限性，各检测方法及指标仍有待于进一步规范和完善。Objective: To study cochlear function of different sensorineural deafness and their clinical significance. Methods: The basic properties of input/output(I/O) of distortion product otoacoustic emission(DPOAE) in 20 normal subjects(40 ears) and 70 cases(93 ears) with sensorineural deafness were studied and analysed. Results: Slope of I/O and thresholds at different frequencies in part of sensorineural deafness cases and normal subjects are similar. Conclusion: Different effect for cochlear active mechanism in sensorineural deafness cases, otoacoustic emission(OAE) is limited for clinical to make use , its clinical significance to need further studies.
