Морфофункциональная оценка слизистой оболочки надтубарного кармана и переднего эпитимпанального синуса

Abstract

Based on autopsy and biopsy material, a morpho-functional assessment of the mucous membrane of the anatomical spaces of the medial wall of the tympanic cavity — separated by fold of the tensor tympani muscle —was carried out. It has been shown that in most cases samples of the mucous membrane of the supratubal recess are represented by multirow or pseudostratified epithelium with loose connective tissue of the lamina propria. On the other hand, the mucous membrane of the anterior epitympanic recess in most cases is represented by flat epithelium with compact connective tissue of the lamina propria, which determines the high gas-absorbing capacity of the mucous membrane. Establishing the boundary of the mucous membrane with a high gas-absorbing capacity in practical terms determines the formation of the tympanic segment when performing open-type tympanoplasty.
