A major sequelae of impacted cerumen (earwax) is conductive hearing loss, which can be deleterious to linguistic, social, and intellectual development, particularly for individuals with mental retardation. The longitudinal incidence (12-year period) of excessive/impacted cerumen and related conductive hearing loss of 117 adults with mental retardation was examined. Results indicated a considerably higher incidence of excessive cerumen and cerumen impaction with associated conductive hearing loss in adults with mental retardation (28%) than in the general adult population (2% to 6%). Moreover, a strong propensity for recurrent cerumen impaction in the mentally retarded population was found. These findings were discussed in view of the management of cerumen impaction among individuals with mental retardation.
耵聍（耳垢）堵塞的一个主要后遗症是传导性听力损失，这可能对语言、社交和智力发育有害，尤其是对智力迟钝的个体。研究了117名智力迟钝成年人的耵聍过多/堵塞及相关传导性听力损失的纵向发病率（12年期间）。结果表明，智力迟钝成年人中耵聍过多和耵聍堵塞伴相关传导性听力损失的发病率（28%）明显高于一般成年人群（2%至6%）。此外，还发现智力迟钝人群有反复发生耵聍堵塞的强烈倾向。针对智力迟钝个体的耵聍堵塞管理对这些发现进行了讨论。
