Cholesteatoma of the maxillary cavity

Rhinolaryngopathologists have to deal with cholesteatoma more than representatives of other dissin, but they are used to meeting it most often in the cavities of the middle ear. Looking through the special literature on this issue, we find only isolated cases of describing the defeat of cholesteatoma of the adnexal cavities of the nose. Without going into a detailed histological and pathological analysis of the question of a pearl tumor, we will briefly only touch on the views and theories of the occurrence of this tumor. Virchow considers the cholesteatoma to be a neoplasm and as proof puts forward the position that normally there are no cellular elements in both the cavities of the middle ear and the appendages of the nose, from which the specified tumor is formed, and they are, as it were, lost. It should be noted that here we are talking mainly about the epidermoid elements because they are the basis of the cholesteatoma. The above-mentioned cells, under favorable conditions for them, begin to grow and, undergoing a number of biochemical processes, form a tumor. As a product of the reaction from the surrounding tissue, cholesterol and fatty acids are released, which contribute to the bonding of growing and peeling epidermoid cells. It is worth noting that the specific cholesteatomic smell that we usually observe in all cholesteatomic neoplasms is mainly a product of decomposed acids and cholesterol.
