The incidence of occlusion of the external auditory canal due to impacted cerumen was determined for 44 mentally retarded subjects in comparison with 44 nonretarded subjects. Otoscopic data were taken by qualified personnel for both groups and subjected to statistical analysis. Results confirmed that retarded adolescents have a significantly higher incidence of occlusion of the external auditory canal due to impacted cerumen than do nonretarded adolescents. Routine otoscopic examinations should be performed on the former group to ameliorate loss of hearing due to impacted cerumen.
对44名智障受试者和44名非智障受试者进行了比较，以确定耵聍栓塞导致外耳道堵塞的发生率。两组的耳镜检查数据均由专业人员采集并进行统计分析。结果证实，智障青少年因耵聍栓塞导致外耳道堵塞的发生率显著高于非智障青少年。应对前一组进行常规耳镜检查，以改善因耵聍栓塞导致的听力损失。
