目的 探讨早期发现小儿听力障碍的筛查方法。方法 采用诱发畸变耳声发射法 (DPOAE)对 4996例新生儿进行听力筛查 ,连续监测异常者 ,最后由脑干听觉诱发电位 (ABR)确诊。结果 DPOAE法筛查阳性 36例(0 72 % )经ABR确诊 10例听觉障碍 ,其中单耳聋 4例 ,双耳聋 6例 ;轻度听觉障碍 1例 ,中度 4例 ,重度 5例。结论 DPOAE测试法适合于新生儿听力筛查 ,是可靠、有效、快速、简便的好方法 ;新生儿科工作者必须重视小儿听力筛查 ,早期干预 ,以达聋而不哑。

Objective To explore the screening way of dysacusia in neonate at early period.Methods Auditory screen detected by DPOAE in all neonates and the neonates with abnormal result were continuously monitored,and the final diagnose was made by auditory brainstem response(ABR).Results Ten of thirty-six neonates with positive result by DPOAE were finally diagnosed to be dysacusia by ABR,including unilateral-ear deafness(4),bilateral-ear deafness(6).There was 1 case with mild,4 cases with moderate and 5cases with serious disorders of audition.Conclusion DPOAE is the credible and effective method for us to screen the dysacusia in neonate.Pediatrician should pay more attention to auditory screen in order to find out the patients earlier.Early intervention should be given to prevent dumb.
