The morphological types of benign tumors located in the nose, paranasal sinuses, and nasopharynx, their features of detection by CT-scan, and their significance as a clinical pathogenetic factor affecting hearing were analyzed. Based on the conclusions of Mouangue-Mbonjo et al. about the correspondence of CT-SCAN results with histopathology in 90.9% of cases, the effectiveness of CT-SCAN in assessing tumor localization and types was also confirmed in this study. The study evaluated 101 patients (groups I and II) based on CT-scan and clinical data. Among them, polyps were the main cause of hearing impairment in group I, while in group II, vascular and epithelial tumors (hemangioma, papilloma, fibroma) prevailed.
G.U. et al. (Mon,) studied this question.
