Hearing function of 35 institutionalized persons with Down syndrome, age 35 to 62 years, was assessed by means of otoscopy, impedance audiometry, brainstem evoked response audiometry, and pure tone audiometry. Using brainstem evoked response audiometry, we determined response thresholds for 59 ears, which compares favorably with pure tone audiometry (20 ears). We found hearing losses of 20 dB to over 90 dB in 56 of these ears. Hearing loss should be considered and, whenever feasible, excluded as a contributing factor in social and mental deterioration in middle-age persons with Down syndrome.
对35名年龄在35至62岁的唐氏综合征机构收容人员的听力功能进行了评估，评估方法包括耳镜检查、声阻抗测听、脑干诱发电位测听和纯音测听。通过脑干诱发电位测听，我们确定了59只耳朵的反应阈值，这一结果与纯音测听（20只耳朵）相比更具优势。我们发现其中56只耳朵存在20分贝至超过90分贝的听力损失。在唐氏综合征中年患者的社会和精神衰退中，应考虑听力损失，并在可行时将其作为一个促成因素排除。
