目的:分析新生儿普遍听力筛查通过而确诊为听力障碍患儿的听力学特点及病因,探讨对高危儿进行听力监测的有效措施。方法:收集6例于2008年1月~2009年6月通过耳声发射作为新生儿听力普遍筛查而在柳州新生儿听力筛查中心确诊为听力障碍患儿的资料,分析病史、就诊情况及听力学检查结果。结果:6例均被确诊为极重度感音神经性聋(1例为单耳),其中3例儿童保健科转诊患儿均确诊为听神经病。确诊为听力障碍患儿具有高胆红素血症、脑损伤综合征、早产低体重及母孕早期感染病史等一种或多种听损伤高危因素。结论:新生儿听力筛查通过而被确诊为听力障碍者,其听力学特点以极重度感音神经性聋为主,使用耳声发射进行听力筛查可漏筛蜗后病变所致的听力障碍。听力损失患儿多数为高危儿。新生儿听力筛查与儿童保健工作、脑损伤高危儿监测相结合,对听力损失高危儿进行听力监测具有重要作用。
Objective:To analyze the audiology and pathogenesis of infants passed the hearing screening but with hearing disorders to find potential risk factors during hearing screening.Methods:Medical history, patient attendance and results of audiometry test of 6 cases who were indentified with hearing impairment by hearing screening in this hearing center from January,2008 to June,2009 were analyzed.Results:All cases were found with profound sensory hearing disorders, three cases with auditory neuropathy were transferred from Child Healthcare Division.Hyperbilirubinemia, brain injury, premature with low birth weight and early pregnancy infection were found in 6 cases.Conclusion:Diseases of retrocochlear, which can cause profound sensory hearing impairment, may be neglected during otoacoustic emission test.Child healthcare service and screening for risks of brain injury should be combined with hearing screening for earlier diagnosis of hearing disorders.
