Justification for endonasal surgical approach for cystic lesions of the maxillary sinus

Abstract

The article discusses the feasibility of endonasal surgical approach for cystic lesions in the maxillary sinus. A comprehensive study of 102 patients with chronic cystic sinusitis was conducted to evaluate anatomical and morphological characteristics of the ostiomeatal complex. CT scans of the PNS were studied using vector analysis measuring the lumen of ethmoid infundibulum and diameter of the natural maxillary ostium, and a histological examination of the mucous membrane structures of the ostiomeatal complex was undertaken. The study found that lesions in the mucosa of ethmoid infundibulum and the natural maxillary ostium are chronic with prevalence of sclerotic changes. At the same time, alongside the whole complex communication system between the sinus and nasal cavity there is a lumen 1,31 ± 0,03 mm in the area of ethmoid infundibulum, and 2,09 ± 0,02 mm in the natural ostium (ρ
