A variety of non-neoplastic and neoplastic conditions involve the nasal cavity, paranasal sinus and are fairly common presentation encountered in clinical practice. Sinonasal lesions are a common finding in all age groups. The lesion of nose and paranasal sinuses are very deceptive so, the presenting features, clinical examination, nasal endoscopy, radiodiagnosis and histopathology are employed conjointly to reach a diagnosis. This cross sectional study was conducted between November 2014 and September 2016. 150 patients with nasal or paranasal sinus lesions attending ENT OPD were included. Among 150 patients there was a male predominance in all lesion except malignant lesions and most of the patients 72 (48%) were in the age group 11- 30 years. Mean age of presentation for benign lesions was 33.64 years and of malignant lesions was 49.14 years. The study showed that 96 (64%) of the nose and PNS lesions were of inflammatory nature followed by 22 (15%) benign, 18 (12%) granulomatous and 14 (9%) malignant, Inflammatory polyp being the most common diagnosis. Haemangioma was the most common benign neoplastic lesion whereas in granulomatous lesions most common diagnosis was tuberculosis. The maximum lesions 74 (49%) were in maxillary antrum. The most common clinical presentation was nasal obstruction, with unilateral nasal obstruction seen in 84 (56%) cases and bilateral nasal obstruction in 50 (33.3%) cases. Angiofibroma 6 (4%) was exclusively seen in adolescent males. Olfactory neuroblastoma 4 (2.6%) was diagnosed in females with mean age of presentation of 30 years. Sinonasal lesions display a complex and interesting spectrum of clinical, radiological and histopathologic features. The non-neoplastic lesions are numerous, the morphologic variants of neoplasms are many and most of them present as polypoid masses which are impossible to distinguish clinically. Hence a proper workup including histopathological and radiological categorization is essential in the management of these lesions.
