ABSTRACT
The article presents the results of histological examination of fragments of pathological tissue fragments of bone density, obtained during the operations of removing the typical massive foci of tympanosclerosis in the area of the medial wall of the tympanic cavity. The obtained data disprove the hypothesis of neoosteogenesis in tympanosclerosis foci and confirm the assumption that tympanosclerosis is a slowly progressing dystrophic disease accompanied by aseptic necrosis of the bone tissue. The authors conclude that the ossified tympanosclerotic foci are the fragments of necrotized bone, i. e. bone sequestra.
