THE APPLICATION OF OTOMICROSCOPY IN THE DIAGNOSIS OF TYMPANOSCLEROSIS

Abstract

Tympanosclerosis (TS) is a special form of sclerosis of the mucous membrane of the tympanic cavity, which is manifested by the formation of so-called tympanosclerotic plaques in it, dense whitish focal thickenings.

This peculiar form of non-purulent lesions of the middle ear was first mentioned by I. F. Cassebohm in 1734. A. Troeltsch in 1869 made the first detailed description of this pathology, and in 1956. F. Zollner proposed the term "tympanosclerosis".

According to the data of different authors, the frequency of occurrence of TS varies greatly. So, J. Sheehy and W. House (1962) found TS in 33% of patients with chronic suppurative otitis media (CHS), S. Asiri (1999) - in 11.6%, A.V. Uryupin (2000) - only in 6.3%. and Yu. M. Ovchinnikov (1975) noted that TS patients account for 5.3% of the total number of patients operated on for severe hearing impairment caused by post-inflammatory fibroplastic changes in the middle ear.
