: Sinonazal kitlelerde 6 yıllık histopatoloji sonuçlarımız

Abstract

Purpose: In this study, it was aimed to compare patients with bilateral sinonasal mass and those who have unilateral sinonasal mass in terms of age, gender and histopathological diagnoses.
 Material and Method: The histopathological results of 549 patients who underwent incisional / excisional biopsy or sinonasal surgery in our clinic between January 2012 and December 2017 were examined. All histopathological diagnoses were divided into 3 groups as benign, malign and non-neoplastic. Distribution rates of cases with unilateral involvement and cases with bilateral involvement were evaluated by age, gender and years. 
 Results: The average age of 549 patients was 40.12 ± 14.31.The most common histopathological diagnosis was nasal polyp (71%). It was observed that 10.6% of histopathological diagnoses were benign, 0.9% malign and 88.5% non-neoplastic. Right sided involvement was observed in 15.7% of the patients, left sided involvement was in 17.7%, and bilateral involvement was observed in 66.7% of the patients. The group which includes patients with non-neoplastic mass was found to have significantly more bilateral involvement than other groups (p = 0.001).
 Conclusion: The most common histopathological diagnosis of sinonasal masses is nasal polyps. Nasal polyps are often bilateral but they can also be unilateral. Unilateral sinonasal masses can be malign, therefore differential diagnosis should be made by biopsy.
