苏州市502例新生儿听力筛查转诊情况总结分析

An analysis of hearing test resutlts of 502 referred infants in Suzhou hearing center

目的了解苏州市下属县（市区）新生儿听力筛查未通过的转诊情况以及其听力筛查情况。方法对转诊至苏州市立医院听力中心的502例患儿进行畸变产物耳声发射和快速脑千听力筛查的初查，然后进行脑干听觉诱发电位和声阻抗的综合诊断检查，并对听力检测结果进行分析。结果在502例患儿中，158例未通过畸变产物耳声发射和快速脑干听力筛查者，需行脑干听觉诱发电位检测。经脑干听觉诱发电位检测119例确诊，其中51例为轻度听力损伤，占42．9％，26例为中度听力损伤，占21．8％，14例为重度听力损伤，占11．8％，28例为极重度听力损伤，占23．5％；39例为失访患儿。在轻度和中度听损伤患儿中，声阻抗为B型的患儿所占比例较大，而在重度和极重度听力损伤患儿中，声阻抗为A型的患儿所占比例较大。结论听力筛查需要引起足够的重视，加强宣传力度，安排专人负责完成各项检查及系统化优生工作。

Objective To investigate current situation of hearing screening and referrence of infants who failed in primary hearing screening in subordinate counties and regions of Suzhou city. Methods 502 infants who were referred to Hearing Screening Center were screened preliminarily by distortion product otoacoustic emissions （DPOAE） and fast auditory brainstem response （ABR）, then they received comprehensively diagnostic and acoustic impedance examinations. Results Among 502 infants, 158 infants failed to pass screening by DPOAE and fast ABR and then they received ABR. 119 infants were diagnosed by using ABR, of which 51 infants （42.9%） suffered from mild hearing impairment, 26 infants （21.8%） suffered from moderate hearing impairment, 14 infants （11.8%） suffered from severe hearing impairment, 28 infants suffered from （23.5%） extremely severe hearing impairment and 39 infants missed follow up. Among the infants with mild to moderate hearing impairment, proportion of the infants whose acoustic impedance was type B was higher, while the proportion of type A was higher in severe and extremely severe hearing impairment groups than in mild and moderate hearing impairment groups. Conclusion The hearing screening needs to be paid more attention and propaganda should be strengthened. The full-time worker should be arranged to conduct all examinations and analyses.
