title: 1984 Hodge memorial Award--surface wrinkles, cell ridges, and desquamation in the external auditory canal.
abstract: 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.
