Clinical and Morphological Substantiation of Treatment of Odontogenic Cysts of the Maxilla.

In the course of histopathological and morphological study, we have examined the structural features of adjacent, pushing and penetrating juxtahilar cysts in relation to the maxillary sinus. The findings obtained in the histological study served as a basis for developing a new method of treatment, the use of which allows creating no fistula with lower nasal passage, and preserving the integrity of all the major anatomical structures of the maxillary sinus, and ensuring the preservation of all unmodified areas of sinus mucosa. A complete removal of cyst and its contents is carried out, bleeding is prevented, and full antiseptic wound cleaning is provided. Total 49 patients were operated. Postoperative complications such as bleeding, edema, inflammation, postoperative pain, partial reduction and complete loss of sensitivity of the upper jaw was 4.08%.
