Introduction: Sinonasal tumours are relatively uncommon tumours in the head-neck region. The aim of the present study was to study the clinico-pathological profile of the sinonasal tumours and its management. Material and methods: It was a Prospective, observational study. Forty Patients with sinonasal tumours, attending the otorhinolaryngology and Head-Neck surgery department of a tertiary-care hospital, Kolkata from October 2017 to September 2018 were selected for the study. Previously treated cases of sinonasal tumour with recurrence were excluded. They were evaluated by detailed history taking, proper clinical examination, relevant radiological imaging followed by biopsy. A clinico-pathological profile was made from the data obtained from these patients. Patients were treated either by surgery, radiotherapy or chemotherapy or a combination as appropriate and followed up regularly. Results: There were 27 males and 13 females in the present study with a male: female ratio of 2:1. Commonest age group was 11 to 20 years. Maximum number of patients encountered were students (30%) followed by domestic workers (20%). Nasal obstruction and epistaxis were the most common mode of presentation (65% each). Out of 40 cases, 25 (62%) had benign and 15(38%) had malignant tumour. Juvenile angiofibroma and maxillary carcinoma were the most common under the benign and malignant varieties of sinonasal tumours respectively. Conclusion: Timely diagnosis and early treatment will decrease the burden of morbidity and mortality in these patients. This study recommends awareness regarding the disease process and health education to people regarding maintenance of hygienic conditions and utilization of health facilities.
