ABSTRACT
Sphenochoanal polyp is a rare form of choanal polyp originating from the sphenoid sinus and extending to the choanae via the sphenoethmoidal recess. We report a case of sphenochoanal polyp in a 15-year-old boy presenting with a 3-year history of chronic progressive nasal obstruction, treated with endoscopic surgery with good post-operative outcome. Sphenochoanal polyp is extremely rare. Symptomatically, it resembles an antrochoanal polyp. Adequate preoperative evaluation based on endoscopic examination and computed tomography (CT) scan or magnetic resonance imaging is necessary for accurate diagnosis and appropriate surgical strategy. Endoscopic excision is the treatment of choice.
