Our Ten-Years Retrospective Histopathological Results in Sinonasal Masses

Objective: We aimed to examine retrospectively the age, gender or whether the mass was single-sided or bilateral in patients who were operated on or biopsied for a sinonasal mass and also to compare and discuss our results with current literature. Material and Methods: The histopathological results of 362 patients who were biopsied or operated due to an intranasal mass between January 2014 and December 2023 were analyzed retrospectively. Pathological results were grouped as benign, non-neoplastic, and malignant. Distribution rates, age and gender, and involvement whether unilateral or bilateral were evaluated. Results: The mean age of the cases was 45.5 years (range: 10-91) Of the patients included in the study, 214 (59%) were male and 148 (4%) were female. Nasal polyp cases prevail among all histopathological lesions with a case number of 235 and a percentage of 65%. 298 out of 362 patients (82.5%) had a non-neoplastic lesion, benign lesions constitute 61 (16.7%) of all histopathological results, and 3 (0.8%) account for a malignant tumor. 53.6% of all patients had bilateral involvement. Conclusion: We obtained approximately the same results with similarly conducted studies in the literature in terms of the distribution of the sinonasal masses. The most frequent histopathological diagnosis was nasal polyp. Most sinonasal masses are recorded to be benign or nonneoplastic however malignancy should also be kept in mind.
