摘要
目的探讨利用畸变产物耳声发射(DPOAE)和纯音听力评价突发性耳聋的方法和效果。方法随机抽取我科2009-2011年收治突发性耳聋患者60例(64耳),所有患者治疗前后均接受纯音测听检查及DPOAE检测,对比两种检测方法的结果变化。结果治疗前后比较,患者DPOAE和纯音听力检测均优于治疗前(P<0.05);治疗后两组间比较,患者DPOAE检测通过率较纯音听力检测更灵敏(P<0.05)。随着患耳听力的改善,听阈恢复率、DPOAE幅值恢复率都逐步提高,但是二者的变化并不同步(P>0.05)。结论 DPOAE检测可反应耳蜗听力功能和毛细胞功能状态,具有无创、快速、全面、特异的优点,能有效地指导临床治疗。
Objective To compare the effect of distortion product otoacoustic emission（DPOAE） and pure tone audiometry（PTA） in the evaluation of sudden deafness.Methods 60 patients（64 ears） with sudden deafness admitted in our hospital from 2009 to 2011 were selected and enrolled in this study.All the 60 patients received DPOAE test and PTA test before and after treatment.The results of the two kinds of tests were compared.Results After treatment,the results of DPOAE test and PTA test were all significantly better than that before treatment（P〈0.05）.After treatment,DPOAE test was found to be significantly more sensitive than PTA test（P〈0.05）.With the improvement of the hearing,the patients＇ hearing threshold recovery rate,DPOAE amplitude were gradually increased,but the change is not synchronous（P〉0.05）.Conclusion DPOAE test can reveal the cochlear hearing function and hair functional status,which is non-invasive,fast,comprehensive and specific.
