Abstract

Choanal polyps are solitary benign tumours which come from one of the paranasal sinuses. Isolated polyp originating from the anterior wall of the sphenoid sinus or from its interior and extending as choanal polyps into the nasopharynx are extremely rare. We report a case of 17 year old female presenting with progressive unilateral nasal obstruction, intermittent nasal discharge and headache. The diagnosis of sphenochoanal polyp was made by endoscopy and confirmed by CT scan paranasal sinuses. It was removed endoscopically via transnasal sphenoidotomy.
