The purpose of the study was to determine the morphological changes that occur in the polypoidal mucosa of the osteomeatal complex in chronic rhinosinusitis. For the study, the surgical material was used - polypomatous mucosa of the osteomeatal complex obtained during FESS. In many cases, modern treatment methods are unable to provide long-term remission of the disease. This prompts the search for new methods of surgical and medical rehabilitation of the mucous membrane in chronic rhinosinusitis, the polypoidal mucosa of the osteomeatal complex is covered with goblet-transformed epithelium, which is unable to perform the transport function of the mucociliary apparatus in themeatus. In the intrinsic layer of the mucous membrane, edema occurs first, which has a vascular origin, and then leukocyte infiltration occurs, which blocks the ostiomeatal complex. Inhibition of mucociliary transport and blockade of the osteomeatal complex are the main pathogenetic factors in the occurrence of exacerbation of chronic rhinosinusitis. Dysregenerative processes in the stromal component also play an essential role in the genesis of polyposis changes in the mucous membrane. Our studies indicate that in chronic rhinosinusitis, the polypoidal mucosa of the ostiomeatal complex is covered with goblet-transformed epithelium, which is unable to perform the transport function of the mucociliary apparatus in the middle nasal meatus. The obtained materials were used to make histological preparations according to generally accepted methods, which were stained with histological and histochemical stains. In chronic rhinosinusitis, the polyposis-altered mucosa of the osteomeatal complex is covered with goblet-transformed epithelium. The mucosa has edema with a pronounced vascular genesis. Blockade of the ostiomeatal complex is the main pathogenetic factor in the occurrence of exacerbation of chronic rhinosinusitis.
