摘　　要：目的:探讨畸变产物耳声发射(DPOAE)对伪聋和夸大性聋的鉴别诊断作用。方法:采用ILO 96耳动态分析仪对外伤后诉听力下降,而又不配合纯音听阈(PTT)检测的患者进行DPOAE检测与分析。结果:经PTT检测的129例(150耳)外伤性听力下降患者中,有102例(121耳),作DPOAE检测结果显示伪聋占66.12%(80/121),夸大性聋占33.88%(41/121)。经ABR检测反应阈值,证实DPOAE检测结果客观、可靠。结论:DPOAE作为外伤后听力损失鉴别诊断的常规检测方法,可对伪聋和夸大性聋作出客观、可靠的诊断和鉴别诊断。Objective：To explore the role of differential diagnosis of distortion product otoacoustic emissions （DPOAE） in pseudohypacusis and exaggerated hearing loss. Method：Detection and analysis of DPOAE were made by ILO96 Otodynamic Analyzer in the patients complaininged of post-traumatic hearing loss and incooperative in pure tone threshold （ PTT ） examination. Result：The detective results of DPOAE in 102 patients （121 ears ） incooperative in PTT examination revealed that pseudohypacusis was 66.12% （ 80/121 ears ）, exaggerated hearing loss was 33. 88% （ 41/121 ears ）. The reactive threshold value determined by auditory brainstem response （ABR） in these patients confirmed that the results of DPOAE were objective and reliable. Conclusion：DPOAE can be used as a routine examination method in differential diagnosis of the post-traumatic hearing loss. It gives an obiective and reliable diagnosis and differential diagnosis for the pseudohypacusis and exaggerated hearing loss.
