Evaluation of structural changes of bone in chronic purulent otitis media

Abstract

Fragments of bone tissue of the temporal bone, obtained during reconstructive-sanitizing operations in patients with chronic purulent otitis media, were studied by light and electron microscopy. An analysis was made of the degree of structural changes in bone tissue in chronic inflammation at the cellular and tissue levels after a histomorphological study in microwave decalcification. The method of diagnosis reliably allowed to differentiate the diseases characterized by the rarefaction of bone tissue, due to chronic inflammation, and also to determine the processes of transformation of bone tissue. The method of diagnosis reliably allows to differentiate diseases characterized by the rarefaction of bone tissue due to chronic inflammation, as well as to determine the processes of bone tissue transformation, however, the study is time-consuming, long-lasting and expensive.
