语言发育迟缓儿童中的听力问题探讨

目的 探讨语言发育迟缓儿童中的听力问题，为儿童语言发育迟缓的临床评估提供参考建议。方法 539例语言发育迟缓儿童均进行听觉行为测试（pediatric audiometer,PA5），有异常者进一步进行耳声发射仪（OAE）、声阻抗仪、听性脑干反应(ABR)检查。结果 发现听力问题在儿童语言发育迟缓中占有一定的比例，听觉行为测试共发现25例异常，筛查阳性率为4.64%；其中15例进行听性脑干反应检查，结果5例听力异常，占阳性筛查者的20%；其中2例为中耳积液，3例为中度听力损失。结论 语言发育迟缓儿童应常规进行听力检查，以期尽早发现听力异常对儿童语言发育的影响，使语言发育迟缓儿童得到早期干预、早期诊治。

Analysis of hearing impairment in children with language developmental delay

Objective To investigate the hearing impairment in children with language developmental delay,and provide reference for clinical evaluation of language delayed children. Methods 539 children with language developmental delay were included,and all were tested for pediatric audiometer (PA5).If the results of PA5 were abnormal,then there was a need to do otoacoustic emission(OAE),Acoustic impedance audiometer and auditory brainstem response(ABR). Result Hearing impairment accounted for a certain proportion in children with language developmental delay;Pediatric Audiometer found 25 abnormal cases,and indicated positive rate of hearing screening was 4.46%;Only 15 of the 25 children were then tested by ABR,5 children were diagnosed as hearing impairment,which accounted for 20% of positive screening;2 cases were middle ear effusion and 3 were moderate hearing loss. Conclusions Children with language delay should do hearing test as a routine,even for children who had already passed neonatal hearing screening.In that case the influence of hearing impairment on child language development earlier can be found and maken the language delayed children receive earlier diagnosis and intervention.
