目的:了解该地区新生儿听力障碍的发病情况。方法:回顾性分析2010年10月～2011年10月廊坊地区出生的79 450例新生儿听力筛查的结果。采用畸变产物耳声发射(DPOAE)进行初筛,初筛阳性者及高危儿42天后采用DPOAE联合自动听性脑干诱发电位(AABR)进行复筛,复筛阳性者采用AABR+ABR+DPOAE+声导抗等听力测试做最后确诊,确定听力障碍的程度和性质。结果:新生儿听力筛查79 450例,初筛率92.5%;初筛通过69 122例,通过率87.0%;复筛8 125例,未通过975例,阳性率12.0%;确诊201例,总发病率2.5‰,其中轻度听力损伤108例,中度听力损伤56例,重度37例。结论:对新生儿进行听力普遍筛查,可早期发现听力异常,及时给予干预,减少听力损害的发生,促进言语发育,提高人口素质。
Objectives: To understand the incidence of neonatal hearing disorders in the area. Methods: The results of hearing screening of 79 450 newborn born in Langfang from October 2010 to October 2011 were retrospectively analyzed. DPOAE was used for primary screening. After primary screening and high risk infants 42 days later, DPOAE combined with automatic auditory brainstem response (AABR) was used to screen the patients. AABR + ABR + DPOAE + Conductance and other hearing tests to make the final diagnosis, to determine the degree and nature of hearing disorders. Results: 79 450 cases of neonatal hearing screening, the screening rate of 92.5%; screening through 69 122 cases, the rate of 87.0%; 8125 cases of re-screening, 975 cases did not pass, the positive rate of 12.0%; 201 cases were diagnosed, total The incidence of 2.5 ‰, including 108 cases of mild hearing loss, moderate hearing loss in 56 cases, severe in 37 cases. Conclusion: The common hearing screening of newborns can detect abnormal hearing in early stage and timely intervention to reduce the occurrence of hearing loss, promote speech development and improve the population quality.
