Abstract
Optical and electron microscopy have been widely used to study the structural features of olfactory epithelium in several Vertebrate species. To date, however, understanding of histopathological alterations in the human olfactory neuroepithelium has been quite limited due to the difficulty in obtaining well preserved, intact fragments of mucosa. The recent introduction of endoscopic biopsy techniques has made it possible to analyze this epithelium in greater detail. In the present work, endoscopic biopsy has been performed on samples from 10 rhinologically healthy subjects. The technique used proved quite simple and did not present any risks or complications. Moreover, all samples were well preserved, as confirmed by histology. In addition, the histological pictures suggest that normal rearrangement of neuroepithelium is not an uniform process but takes place following a zone pattern with distinct dynamics between neurosensorial and support cells. Greater diffusion of this technique would not only make it possible to use different techniques to gain more detailed knowledge of tissue structure, ultrastructure and dynamics in human neuroepithelium, but it would also provide improved diagnostic and forensic evaluation in cases of anosmia, disosmia and hyposmia.
