Schwannoma (neurilemmoma) is a benign tumour that arises from the Schwann cells which cover the nerve sheaths of the peripheral or autonomic nervous system especially the sympathetic system. Reported cases of schwannoma arising from the sinonasal tract are rare. We report a case of a 28-year-old man who presented to otolaryngology—head and neck surgery clinic with left cheek swelling and left-sided nasal obstruction for 1-year period. Endoscopic examination and high-resolution CT scan revealed a homogenous expansile mass occupying the left maxillary antrum extending to the left orbit and left ethmoidal air cells. The mass was excised through endoscopic endonasal approach followed by Caldwell-Luc approach for the residual tumour. Postoperative histopathological examination revealed benign type Antoni A schwannoma.
