Paranasal sinus (PNS) and nasal cavity tumors are rare, and account for 3% of all head and neck malignancies. Experience with endoscopic technique, advances in visualization, introduction of image guidance and development of surgical tools has led to a shift towards the treatment of PNS and nasal tumors through endoscopic approaches. Retrospectively study was done in a tertiary care institute from January 2008 to December 2018. Inclusion criteria-males and females irrespective of age, histologically proven benign tumors of paranasal sinus and nasal cavity. Exclusion criteria-patients diagnosed with juvenile nasoangiofibroma (JNA), histologically proven malignant tumors of paranasal and nasal cavity, involvement of skin, orbital extension, intracranial extension of tumor. 26 patients of benign paranasal sinus malignancy were operated, male-14, female-12. Most common being inverted papilloma (n-16, 61.5%), Benign PNS and nasal cavity tumors not involving skin, orbit, tumors with intracranial extension can be managed by endoscopic excision.
