【摘要】 目的早期发现和诊断新生儿先天性耳聋。方法对2002年6月至2004年12月我院出生的4666例新生儿进行耳声发射(TEOAE)筛查,连续监测异常者,最后由中耳分析和诊断型听性脑干反应(ABR)确诊。结果3次筛查不通过的46人行中耳分析和诊断型ABR测试:除1例外耳畸形未行中耳分析外,其余全部为A型曲线。ABR测试14人双耳通过(ABR<50dBSPL),16人双耳和16人单耳不通过(ABR≥50dBSPL)。先天性耳聋发病率6.86‰(32/4666)。结论对新生儿应进行早期听力筛查,TEOAE、中耳分析和诊断型ABR测试有利于新生儿先天性耳聋的及时发现和早期干预,提高聋儿生活质量。更多还原

【Abstract】 Objective The early detection of newborn congenital hearing loss. Method Retrospec-tively sum up the results of newborn hearing screening by transiently evoked otoacoustic emission(TEOAE) in 4666 newborn in our hospital from 2002 to 2004.Those infants who failed in the TEOAEtest received middle ear construe and ABR test again when they were in 120 days. Results 46 newbornstest and failed the TEOAE screening in the hospital. middle ear construe infants passed of 45 case , 14infants passed ABR test of both ear(ABR<50dBSPL), 16 infants had been confirmed hearing loss of twoears(ABR≥50dBSPL), 16 infants had been confirmed hearing loss of one ear. prevalence of neonatalhearing disorders was 6.86‰(32/4666). Conclusion The middle ear construe and ABR screening wereproved to be an effective method for newborn hearing screening respectively in 6- month old infants,which estabilshes a foundation to interfere in congenital hearing loss in early stage.更多还原
