The phenomenon of epithelial migration from the tympanic membrane laterally along the external auditory meatus has long been recognized, and the site of keratin desquamation observed. In this study, the surface features of deep canal epithelium have been studied in 14 human temporal bones, and skin removed from 21 human temporal bones has been sectioned and studied by light microscopy. The findings reveal the role of hairs and ceruminous glands in the desquamation of deep canal stratum corneum, and elucidate the migratory mechanism. The formation an distribution of keratin wrinkles and cellular ridges in the external canal are explained.
鼓膜上皮沿外耳道向外耳道外侧迁移的现象早已为人所知,并且观察到了角质脱屑的部位。在本研究中,对14块人类颞骨的深部耳道上皮表面特征进行了研究,对从21块人类颞骨上取下的皮肤进行了切片并通过光学显微镜进行了研究。研究结果揭示了毛发和耵聍腺在深部耳道角质层脱屑中的作用,并阐明了迁移机制。对外耳道中角质皱纹和细胞嵴的形成与分布进行了解释。
