Recent work carried out at the Ear Pathology Research Laboratory has demonstrated that cerumen plugs consist of a large amount of keratin debris. In this study the site of origin of this keratin was investigated. This was done by histologically examining these cerumen plugs without disturbing the natural relationship between the plug and the surrounding epithelium. We have clearly demonstrated that a cerumen plug consists of keratin arising from the migratory epithelium of the deep external auditory canal and epithelium of the superficial external auditory canal.
耳病理学研究实验室最近开展的工作表明，耵聍栓塞由大量角蛋白碎屑组成。在本研究中，对这种角蛋白的起源部位进行了调查。这是通过对这些耵聍栓塞进行组织学检查来完成的，同时不破坏栓塞与周围上皮之间的自然关系。我们已经清楚地证明，耵聍栓塞由来自外耳道深部迁移上皮和外耳道浅部上皮的角蛋白组成。
