Hearing impairment and otologic problems have been reported to be prevalent among individuals with Down syndrome. This study was designed to determine whether children with Down syndrome have a higher prevalence of auditory abnormalities than do children with other forms of mental retardation. Hearing, impedance, and otoscopic examinations were performed on 30 children with Down syndrome and 30 children without Down syndrome matched for CA and IQ. Results indicated that the children with Down syndrome had a significantly higher prevalence of hearing impairment and otologic disorders.
据报道，听力障碍和耳科问题在唐氏综合征患者中很普遍。本研究旨在确定唐氏综合征患儿的听觉异常患病率是否高于其他形式智力迟钝的儿童。对30名唐氏综合征患儿和30名年龄与智商相匹配的非唐氏综合征患儿进行了听力、阻抗和耳镜检查。结果表明，唐氏综合征患儿的听力障碍和耳科疾病患病率明显更高。
