Morphological changes of the mucous membrane in traumatic injuries of the maxillary sinus

The article presents the results of a study on the characteristics of post-traumatic pathological processes in the mucosa of the maxillary sinus in experimental animals. It is established that the fracture of the bony walls of the maxillary sinus of the sheep causes the development of alterative-exudative inflammation of the mucous membrane of the sinus, which is expressed in the formation of swelling immediately after injury followed by increase till the seventh day. In a more long-term period - 4 weeks after injury in the mucosa predominate in chronic post-traumatic process with signs of multilayered metaplasia of epithelium to stratified squamous and own overactive glands sinus.
