Data were obtained using the assisted self-administered structured questionnaire.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>All the studied age groups had unilateral sinonasal masses with peak age groups of &gt;50 years at 41.1%. The second and third recurrent episodes occurred in 10.7% and 3.6%, respectively. The most common nasal manifestations were nasal blockage (71.4%). Majority of the extranasal manifestations were otological (39.3%) and ocular (7.1%). The most common affected nostril was the right nostril (62.5%). The most common site of origin was maxillary sinus (42.9%). Majority of the histological diagnoses were benign tumours in 71.4%. Majority of benign masses were inverted papilloma (32.1%) and majority of malignancies were squamous cell carcinoma (23.2%). Major surgical interventions were intranasal excisional biopsy (44.6%) and intranasal polypectomy (17.9%). There were 3.6% recurrence and 1.8% mortality recorded in this study.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Unilateral sinonasal mass is common and it can affect any of the nostril, with late presentations due to pre-hospital self-treatment. It could be benign or malignant and mainly surgical excision and chemo-radiotherapy are the treatment options in malignant types.
