Abstract

Choanal polyp is an isolated polyp that emerges from paranasal sinus and extends to the nasopharynx. It usually originates from the maxillary sinus, however in rare cases it could arise from other sinuses or even various nasal structures. Although its etiology remains unknown, it is a common finding in antrochaonal polyp to have a wide antrum ostium which has been suggested to play a possible role in the pathogenesis. The state of sphenoid sinus ostium in sphenochanal polyp hasn’t been explored before. We herein report the case of a 14-year old boy with chronic rhinosinusitis who also had left sphenochoanal polyp with a wide sphenoid sinus ostium which successfully been managed through an endoscopic surgical approach.

Keywords: Choana, Polyp, Sphenoid, Ostium, Endoscope.
