| Abstract |
Background: The nasal cavity and the paranasal sinuses form a single functional unit. Sino nasal tumours are characterized by low incidence, nonspecific symptoms, and late presentation. The sinonasal tumours encompass an entire range of both epithelial and non-epithelial tumours. Aims & Objectives: The present study aims to determine incidence, age, sex, site, mode of presentation and histological types of various benign sinonasal tumours over a 5 year period. Methods: 93 benign sinonasal tumors biopsied or surgically excised over a period from Janauary 2007 to October 2011 were studied. Results: The incidence of benign sinonasal tumors was 0.2%. All age groups were involved with a mean age of 42.5 years. The male to female ratio was 1.7:1. The maximum number of cases was present in the nasal cavity (88%). Inverted papilloma was the commonest benign tumor. The most common mode of presentation was nasal mass. Conclusion: The clinical and radiological features of masses of nasal cavity and paranasal sinuses are overlapping and often only a provisional diagnosis is possible. Definite diagnosis requires histopathological examination.
