Objective To identify,using screening tests,infants with hearing impairment in order to evaluate whether hearing aides and language training were beneficial.Methods From 2007 to 2010,Otoacousfic emission (OAE) and auditory brainstem response (ABR) was used to diagnose infant hearing-disorders at Wuxi maternal and child hospital.Depending on parental permission,those diagnosed with hearing impairment were divided intervention and non-intervention groups.Additionally,a normal control group was constructed children with normal hearing.The Gesell Developmental Schedule (verbal) was used to evaluate the effects of intervention.Results A total of 11 697 infants were screened.930 infants (76.5‰)did not pass the first screening.Of these,a second screening identified 183 person (15.6‰) with hearing concerns.Rescreening finally diagnosed 24 person (2.1‰) as having a hearing disorder.The ratio of hearing disorder declined from 2007 (3.9‰) to 2010 (1.4‰).Verbal DQ scores for both the intervention and non-intervention groups were lower than for those in normal control group.When compared the scores for the intervention group were high than for those of the non-intervention group (P ＜ 0.05).Conclusions The incidence of hearing disorders declined throughout the four year period of the study.Intervention via hearing aids and language training was helpful in promoting verbal intelligence development.%目的 了解我院新生儿听力障碍发生率和听力障碍干预效果,促进听力障碍婴儿言语智能发育.方法 应用耳声发射分析仪和听觉脑干诱发电位对2007-2010年无锡市妇幼保健院出生的婴儿进行听力筛查和听力障碍诊断,对确诊听力障碍婴幼儿根据家长对干预的依从性分为干预组和非干预组,同时选择同期出生听力正常儿童为对照组,采用Gesell发育量表进行言语能发育商测定,评估干预效果.结果 研究期间总共筛查11697名婴儿,初筛未通过930例(79.5‰),复筛未通过183例(15.6‰),确诊听力障碍24例(2.1‰),听力障碍确诊率由2007年的3.9‰逐年下降至2010年的1.4‰.听力障碍婴幼儿干预组和非干预组言语能发育商均低于对照组[(82.5±10.3)、(67.0±14.4)比(94.5±5.7)],且非干预组低于干预组,差异均有统计学意义(P＜0.05).结论 我院婴儿听力障碍的确诊率呈逐年下降趋势,佩戴助听器和语言训练综合干预有助于提高听力障碍婴幼儿的言语智能发育.
