目的了解诱发性畸变产物耳声发射法(DPOAE)听力筛查在本地区的应用价值及筛查阳性率。方法用DPOAE仪测试出生后3～5d的新生儿(初筛),未通过者于30～42d进行复筛。复筛未通过者转诊进行诊断性检查。结果 8770例正常足月新生儿听力初筛的通过率为86.00%,1218例(14.00%)未通过。692例于生后30d复筛,555例(80.20%)通过复筛,未通过的137例(1.56%)进行了转诊。15例(0.17%)被诊断听力损失。结论 DPOAE法听力筛查筛查效果良好。应加强听力筛查宣教,以提高复筛率。
Objective To investigate the value of DPOAE audiology screening in this region and the positive rate of screening. Methods DPOAE instrument was used to test newborns 3 ~ 5 days after birth (initial screening), and those who failed to do so were re-screened 30 ~ 42 days later. Referral failed screening for diagnostic tests. Results 8770 cases of normal term newborn hearing screening rate of 86.00%, 1218 cases (14.00%) did not pass. 692 cases were screened 30 days after birth, 555 cases (80.20%) were re-screened and 137 cases (1.56%) failed. Fifteen patients (0.17%) were diagnosed with hearing loss. Conclusion DPOAE hearing screening screening effect is good. Hearing screening and education should be strengthened to improve the screening rate.
