目的探讨和分析学龄前儿童听力筛查中未通过的原因。方法应用瞬态声诱发耳声发射(TEOAE)对2005年7月-2007年2月在我所入幼体检的1836例学龄前儿童进行听力筛查。入幼体检当日,进行TEOAE测试。对“未通过”者,在去除原因1个月进行第二次TEOAE测试。复筛仍“未通过”者,转往嘉兴听力诊断指定医疗机构应用听觉脑干诱发电位(ABR)做诊断性检查来评估听力水平。结果接受初次筛查的1836例学龄前儿童。其中1670例通过了初筛,通过率91%。初筛未通过的147例,在1个月后进行复查,复查通过128例,通过率为87.1%。复查仍未通过的19例,其中4例已经确诊为听力损失。在1836例学龄前儿童中听力损失的发病率为0.21%。另有15例在随访中,尚未诊断。初筛的假阳性率占8%。结论总结听力筛查中出现假阳性的原因。归纳OAE的优势和不足。
Objective To explore and analyze the causes of preschool children’s hearing screening failure. Methods Transient acoustic evoked otoacoustic emissions (TEOAE) were used to screen 1836 preschool children who were admitted to our hospital from July 2005 to February 2007. On the day of admission, carry out the TEOAE test. For the “failed” who, remove the cause of 1 month for the second TEOAE test. Screening is still “failed ” who go to Jiaxing hearing diagnosis of designated medical institutions using auditory brainstem response (ABR) diagnostic tests to assess the level of hearing. Results 1836 pre-school children undergoing primary screening. Among them, 1670 cases passed the preliminary screening and the passing rate was 91%. The 147 patients failed to pass the screening test were reviewed after 1 month, 128 patients passed the review, and the passing rate was 87.1%. Of the 19 cases that have not yet been reviewed, 4 have been diagnosed with hearing loss. The incidence of hearing loss in 1836 preschool children was 0.21%. Another 15 cases were followed up, not yet diagnosed. The false positive rate of primary screening accounted for 8%. Conclusions The reasons for false positives in hearing screening are summarized. Summarize the advantages and disadvantages of OAE.
