摘要: 目的 建立南京市托幼机构听力保健网络,对迟发性听力损失进行早期识别和干预,并评价听力保健网络的应用效果。方法 通过建立听力保健网络对南京地区托幼机构儿童进行听力筛查、诊断和随访。听力初筛应用畸变产物耳声发射(DPOAE),初筛未通过的儿童半个月内进行复筛,听力复筛采用DPOAE和声导抗检查,复筛未通过的儿童进行临床诊断和听力学评估,确诊为迟发性听力损失的儿童同时行言语评估、助听干预和听力言语的随访。结果 2019年5月—2022年9月共有29 919例托幼机构儿童完成听力筛查,其中3208例(10.7%)初筛未通过,1437例(47.7%)复筛未通过,747例完成听力学诊断,70例(0.23%)儿童诊断为迟发性听力损失,其中,20例伴有语言发育迟缓,12例验配了助听器,2例行人工耳蜗植入,此外还完成了53例儿童的言语评估和听力学随访。结论 托幼机构听力筛查有助于早期发现迟发性听力损失和语言发育迟缓的儿童,建立托幼机构听力保健网络有利于儿童听力损失的早期识别和干预。Abstract: Objective To establish a hearing care network for preschool children in Nanjing, to perform early identification and intervention for delayed hearing loss, and to evaluate the application effect of the hearing care network.Methods Through the establishment of a hearing care network, hearing screening, diagnosis and follow-up of preschool children were conducted. Distortion product otoacoustic emissions(DPOAE) was adopted for primary hearing screening. Children who failed in the primary screening were re-screened within half a month. DPOAE and acoustic impedance test were used for hearing re-screening. Clinical diagnosis and audiological evaluation were performed for children who failed in the re-screening. Speech assessment, hearing aid intervention, and audio-speech follow-up were conducted for children diagnosed with delayed hearing loss.Results Among 29 919 preschool children completing the hearing screening from May 2019 to September 2022, 3208 cases(10.7%) failed the primary screening and 1437 cases(47.7%) failed the re-screening. Total 747 children completed the hearing diagnosis, and 70 children were diagnosed with delayed hearing loss, with a detection rate of 0.23%. Among them, 20 cases were accompanied by language development delay, in which 12 cases received hearing aids and 2 cases received cochlear implantation. In addition, speech assessment and audiological follow-up were completed for 53 children.Conclusion The hearing screening for preschool children is beneficial for early detection of children with delayed hearing loss and language development delay. Besides, the establishment of hearing care network is conducive to early identification and intervention of children with hearing loss.
