摘　　要：目的探讨畸变产物耳声发射(DPOAE)在幼儿听力筛查中的应用。方法应用DPOAE对100名幼儿园儿童(200耳)进行听力筛查,纯音对2、3、4 kHz 3个频率两次测试,耳声发射响应点在通过/转介线以上,信噪比>10 dB为筛查通过。结果94名儿童双耳通过筛查,4名儿童因耵聍栓塞双耳未通过筛查,取出耵聍后复筛通过;2名儿童单耳因分泌性中耳炎未通过筛查,治疗后复筛通过。结论DPOAE适用于幼儿听力筛查,建议将其列为每年的幼儿体检项目。Objective To investigate the usage of distortion product otoaooustic emissions （DPOAE） in normal infants hearing screening. Methods One hundred infants （200 ears） without clinical condition of illness were checked in GSI 70 DPOAE screening. The pure tones were 2,3,4 kHz, the OAE screener scored the test result as a pass, when the responses were above the PASS/REFER line and the signal - tonoise was at least 10 dB. Results Ninty - four infants （ 188 ears） passed hearing screening. Four infants （8 ears） with eemminous impaction didn＇t pass screening; after extracting impacted cerumen from the external auditory meatus, the 4 infants （8 ears） passed screening. Two infants （2 ears） with secretory otitis media didn＇t pass screening, but after medicine treatment for 1 week, they passed screening too. Conclusion DPOAE has advantages in infants hearing screening.
