[Site-specific, structural and ultrastructural characteristics of endonasal cavernous tissue exemplified by the inferior turbinate in man. Light and transmission electron microscopy study].
The cavernous tissue of the nose has been studied morphologically for now more than 150 years. Even though the majority of new findings was already described in the second half of the last century and is associated with scientists like Kölliker, Kohlrausch and Zuckerkandl. The vascular structures, usually described as "cavernous tissue" or "swell bodies" are located in different parts of the nasal mucosa, but mainly in the inferior turbinate. In the present paper the author demonstrates the results of his studies on the structure and ultrastructure of smooth muscle components of nasal swell bodies based on light - and transmission-electron microscopic findings. Light microscopic observations already reveal the differences in vascular wall structure between areas adjacent to the epithelium and those parts of the vessels located in the deeper parts of the tunica propria. Ultrastructural examination shows differences in size and density of smooth muscle cells in different parts of the cavernous tissue; it also demonstrates the variant appearance of the basal lamina of these muscle cells. The results are discussed and compared with the appropriate literature.
