Human external auditory canal skin, with a special emphasis on the secretory system, was studied by light, transmission electron and scanning electron microscopy. Two types of secretory glands were observed: modified apocrine (ceruminous) and sebaceous. The sebaceous secretory cellere homogeneous; on the other hand, modified apocrine secretory cells contained heterogeneous secretory granules. They were ither dark granules or light granules. Evidence to support both the apocrine as well as the eccrine mode of secretion was noted in the modified apocrine gland. This finding is partly in agreement with early reports based on light microscopy with suggested only an apocrine mode and data based on transmission electron microscopy which showed only the eccrine mode. Significance of the secretion by the external ear canal and its role in a local immune defense system is discussed.
通过光学显微镜、透射电子显微镜和扫描电子显微镜对人类外耳道皮肤进行了研究，特别关注了其分泌系统。观察到两种类型的分泌腺：改良顶泌腺（耵聍腺）和皮脂腺。皮脂腺分泌细胞是均匀一致的；另一方面，改良顶泌腺分泌细胞含有异质性分泌颗粒。它们要么是深色颗粒，要么是浅色颗粒。在改良顶泌腺中发现了支持顶泌分泌方式以及外分泌分泌方式的证据。这一发现部分与早期基于光学显微镜的报告一致，早期报告仅提出顶泌分泌方式，也与基于透射电子显微镜的数据一致，后者仅显示外分泌分泌方式。讨论了外耳道分泌的意义及其在局部免疫防御系统中的作用。
