Abstract
Today, there are several diagnostic methods that allow you to determine the exact size and nature of periapical formations. In addition, there are studies that describe the thickening of the sinus mucosa in patients with periapical lesions and show a causal relationship. Objectives: This study was to study the morphological changes in the cysts of the maxillary sinus. Methods: 50 patients with maxillary sinus cysts were evaluated. A total of 50 maxillary sinuses (13 men and 12 women) were analyzed taking into account changes in density in the sinus cavity. The thickening of the sinus mucosa and periapical lesions was measured in the caudal-cephalic direction. The axial and sagittal axes were taken as a basis on the sagittal and coronal sections. The presence of opacities was not directly related to periapical lesions. Conclusions. Lesions of the maxillary sinus floor have been associated with chronic periapical lesions larger than 4 mm. Clouding or thickening of the sinus mucosa was not associated with periapical lesions.
Highlights
Inflammatory diseases of the nose and paranasal sinuses in the last decade have firmly occupied the first place in the overall structure of the incidence of ENT organs, both in the analysis of accessibility to the polyclinic and in the group of patients undergoing treatment in inpatient conditions [1]
In the second group of observations in 18 patients in the mucous membranes, there was a cystic change in the lumen of the glands with the presence of secretions in the cavities, with atrophy of the epithelium, there are small glandular tubes widi proliferation of epithelial cells, convoluted
In the sections - a polypoid formation covered with a multilayer transitional epithelium (a), consisting of a large number of glands lined with proliferating prismatic epithelium (b). mucus (c) The stroma is edematous, represented by fibromyxomatous tissue with abundant lymphoplasmacytic and leukocytic infiltration
Summary
Inflammatory diseases of the nose and paranasal sinuses in the last decade have firmly occupied the first place in the overall structure of the incidence of ENT organs, both in the analysis of accessibility to the polyclinic and in the group of patients undergoing treatment in inpatient conditions [1]. There was a significant increase in the number of diseases of the nose and paranasal sinuses both in absolute numbers and their share in the structure of the general ENT - morbidity, which annually increased by 1.5-2% and reached 52.7% [2]. Sinus cysts are one of the most common diseases in clinical practice. Cysts of the maxillary sinuses are a very common disease that is often an incidental clinical finding on radiography and computed tomography of the paranasal sinuses [4].
