Analysis of the results of morphological examination of surgical samples in tympanosclerosis

Tympanosclerosis, cholesteatoma, tympanic cavity, morphologyAbstract
In our study, we performed histological examinations on fragments of pathological bone tissue removed during surgery from patients with tympanosclerosis, aged 18 to 60 years, who were treated in the adult ENT department of the Tashkent Medical Academy. The examinations were primarily conducted on samples from the horizontal part of the facial nerve canal, which exhibited typical hyaline and calcified foci of tympanosclerosis. In all cases, these individual fragments of pathological tissue with bone-like density were relatively easily separated from the inferior bone of the medial wall of the tympanic cavity as a single block (layer). Only microsurgical needles, hooks, and microclamps were used for their removal, without the need for chisels or milling cutters. These fragments often resemble normal bone tissue in appearance.
