Retrospective analysis of histopathological findings of benign sinonasal masses

Introduction: Nasal polyps are the most common types of benign sinonasal masses. In addition, some histopathological diagnoses like rare sinonasal papilloma, hemangioma and Respiratory Epithelial Adenomatous Hamartoma (REAH) are also observed. The purpose of the present study is to examine the distribution of the masses seen in sinonasal area in terms of histopathological types, and to determine the distribution according to age and gender. Material and Method: A total of 203 patients, who were operated due to benign nasal mass between January 2008 and January 2018 in Tokat State Hospital and whose histopathological diagnoses were obtained, were included in the study. The patients were divided in terms of their histopathological types. These histopathological types were analyzed according to the gender and age range. Results: A total of 128 of the patients were male and 75 were female. The mean age was found as 42.23 (Males: 41.96±18.9, Females: 42.68±19.1). The most common sinonasal mass was nasal polyp (89.1%), and the other histopathological diagnoses were sinonasal papilloma (4%), REAH (2.4%), lobular capillary hemangioma (LKH) (2.9%) and fungal rhinosinusitis (0.9%). Conclusion: The histopathological findings of benign sinonasal masses vary according to age and gender. Antrochoanal polyps are seen mostly at younger ages, nasal polyps, which are associated with chronic sinusitis, are seen in middle age, and inverted papilloma and REAH are detected in advanced age ranges
