目的：通过分析7例新生儿期通过听力筛查，而后确诊为永久性听力损失患儿的情况，探讨新生儿听力筛查假阴性的情况和迟发性听力下降的出现原因。方法收集2010年11月至2013年10月间就诊于我院的曾于新生儿期行听力筛查通过，而确诊听力障碍者共7例。对其病史、临床表现、听力学及影像学检查的结果进行分析。结果7例小儿中确诊重度听力障碍5例，极重度听力障碍2例，其中1例为听神经病。结论出现这些情况的原因可能为新生儿听力筛查假阴性及迟发性听力障碍。对新生儿期通过了听力筛查的婴幼儿应重视后期随访。

Objective To report 7 cases of neonates who passed hearing screening but later were found to have perma-nent hearing loss, and discusses false negative hearing screening in newborns and possible late-onset hearing loss. Methods Negative neonatal hearing screening data collected in our hospital between November 2010 and October 2013 were reviewed and 7 cases of confirmed hearing loss were identified. Patient history, clinical manifestations, audiology and imaging results were analyzed. Results Among the 7 cases of confirmed severe hearing impairment, 5 were rated as severe and 2 as pro-found with 1 diagnosed as auditory neuropathy. Conclusion The reasons for the 7 confirmed hearing loss cases that had passed neonatal hearing screening are thought to be unrecognized false negative results or possible late-onset hearing impair-ment. It is therefore important to follow up infants even though they have passed neonatal hearing screening.
