摘　　要：目的探讨畸变产物耳声发射(distortion products otoacoustic emission,DPOAE)结果与听力结果的关系,为对患儿家长进行正确的健康宣教提供理论支持。方法随机从我院听力中心抽取304例初筛或复筛一耳或双耳未通过患儿,就诊后分别进行全面听力检查,即声导抗、DPOAE、多频稳态听觉诱发反应(auditory steady-state evoked responses,ASSR)、脑干听觉诱发电位,并以具有频率特性的多频稳态判断听力结果。结果经DPOAE测试分为通过耳组和未通过耳组,未通过耳组的正峰曲线比例少于通过耳组(P<0.05)。通过耳组听力正常210耳(93.8%)、轻度受损10耳(4.5%)、中度受损2耳(2.0%)、极重度受损2耳(2.0%),未通过耳组听力正常82耳(21.4%)、轻度受损60耳(15.6%)、中度受损90耳(23.4%)、重度受损36耳(9.4%)、极重度受损116耳(30.2%),未通过耳组听力受损程度较通过耳组严重(P<0.05)。结论 DPOAE筛查通过是诊断听力正常的标准,DPOAE通过者说明患儿的耳蜗功能和外耳中耳功能正常,DPOAE通过耳中93.8%听力正常,DPOAE未通过耳中78.6%存在不同程度的听力损失,通过全面听力检测综合分析才能作出正确诊断。Objective To explore the relationship between the results of distortion product otoacoustic emission(DPOAE)and the hearing results,and to provide correct theoretical support for the health education of the parents.Methods Drawn from our hearing center in random,304 cases who were not passed the test of early screening or compound sieve one ear or two ears were accepted comprehensive hearing examination,namely acoustic immittance,DPOAE,multiple frequency steady state(ASSR),brainstem auditory evoked potential.The hearing results are judged by multi frequency steady state with frequency characteristics.Results After DPOAE test,they were divided into the ear group and the non-passing ear group.The positive curved line of not passed group was letter than the pass group(P<0.05).The passed group hearing showed that normal ears was 210(93.8%),mild damage ears was 10(4.5%),moderate damage ears was 2(2.0%),extremely severe damage ears was 2(2.0%).The not passed group hearing showed that normal ears was 82(21.4%),mild damage ears was 60(15.6%),moderate damage ears was 90(23.4%),severe damage ears was 36(9.4%),extremely severe damage ears was 116(15.6%).The hearing damage of not pass group was severe than the pass group(P<0.05).Conclusion DPOAE hearing screening is a standard for diagnosing normal hearing.The patients passed DPOAE indicated their cochlear,outer and middle ear is normal.DPOAE through the ear 93.8%means normal hearing,DPOAE did not pass 78.6%mean different degree of hearing loss.It is requires a comprehensive hearing test and analysis to make a correct diagnosis.
