This study aimed to evaluate histopathological polyps in patients with chronic rhinosinusitis. In histological preparations of the first group of patients with polypous rhinosinusitis, morphological changes are characterized by hyperplasia of the mucosal epithelium due to prolonged catarrhal inflammation and mucus secretion by papillary growth, cystic changes in the lumen of the stromal glands, as well as focal inflammatory cell infiltration. Based on the results of histological examination of the second group of patients, it can be noted that morphological changes are mainly characterized by cystic lesions of the mucosal glands, as well as the integumentary epithelium with focal or diffuse inflammatory cell infiltration.
