Anatomical and histological features of the state of ostiomeatal complex structures in patients with cystic lesions of the maxillary sinus

Abstract

The article provides the study of anatomo­morphological features of ostiomeatal complex structures condition based on complex examination of 102 patients with chronic cyst sinusitis. The vector analysis of paranasal sinuses СT with the measurement of the ethmoidal infundibulum gleam and diameter of natural anastomosis of the maxillary sinus is made, and histologic research of a mucous membrane of ostiomeatal complex structures is provided. As a result of the research it was determined that the damage of mucous membrane in the area of ethmoidal infundibulum and the natural anastomosis of the maxillary sinus had chronic nature with sclerosis of the genuine plate of mucous membrane and, quite often, hyperplasia and hypersecretion of mucous glands. The gleam of the complex system of the sinus communication with the nasal cavity remains over the whole perios constituting 1.31±0.03 mm – in the area of ethmoidal infundibulum, and 2.09±0.02 mm – in thearea of natural anastomosis of the maxillary sinus (p < 0.01).

The Importance of Light Diagnosis in Joint Injuries of the Walls of the Upper Jaw Cavity

“…Treatment of injuries of the middle part of the facial bone is mainly focused on restoring the integrity of the cheek and upper jaw, with no emphasis on restoring the integrity of the walls of the upper jaw cavity. This, in turn, prolongs the healing of injuries and leads to complications [2,3,4,5,6,7,9]. In injuries of the middle part of the face, X-rays of the correct projection are usually used, but X-rays of the lateral projection are also used in some cases, as X-rays of the correct projection do not provide accurate information.…”
