[Chronic diseases of the mucous membrane of maxillary cavities, nasal ducts and ethmoidal cells in the light of endoscopic-radiographic correlations ].

In the material of 124 patients with chronic inflammation of the mucous membrane of maxillary cavities, nasal ducts and ethmoidal cells, there was performed a comparative analysis of endoscopic and radiographic examination results. There was shown higher efficacy of endoscopy in revealing multiple changes, especially of polypous hypertrophy of the mucous membrane, in the assessment of nasal concha condition, and of patency of the orifices of maxillary sinuses. Endoscopic-radiographic divergences observed in about 9% of cases are considered by the authors to result from differentiation and equivocal appearance of some radiographic condensations.
