Ultrastructure of the Epithelium in Atrophic Rhinitis: Scanning Electron Microscopic Studies

Abstract

Biopsies from nasal mucosa of patients with atrophic rhinitis were studied in the scanning electron microscope. A keratinized squamous epithelium, resembling skin, is seen over large areas. Desquamation of horny cells is pronounced and abnormal, with large desquamated scales forming the basis for the well-known crusts. Openings from submucosal glands and goblet cells are very infrequent. The small amount of mucus is dehydrated in situ, because of the lack of cilia.
