Pathomorphological changes of the Schneiderian membrane in the mixed form of iatrogenic maxillary sinusitis of stomatogenic origin

Objective: To study the morphological changes of the Schneiderian membrane in the mixed form of iatrogenic maxillary sinusitis of stomatogenic origin. Material and methods. Reactive changes of the mucous membrane of the maxillary sinus were studied in 24 (100 %) patients with the presence of a foreign body in the lumen of the sinus. To differentiate the observed changes in the mucosa Manasse’s pathomorphologic classification was used. Immunohistochemical reaction with monoclonal antibodies CD 8, CD 56, CD 68, CD 138, CD 43 was carried out. Photo documentation was constituted by the computer system, binocular microscope Axiolab, digital camera Axiocam and «AxioVision 4.8» software. Statistical processing of the results was carried out according to the tables of R. B. Strelkov. The significance of differences of the results was estimated using the Student-Fisher method for the confidence level of not less than 95 %, which is common for biological and medical research (p
