Choanal polyps are solitary benign growths that can cause unilateral nasal obstruction. A frontochoanal polyp originates from the frontal sinus and extends to the nasopharynx.

Findings on endoscopy and computed tomography suggested frontochoanal polyp, and endoscopic treatment was successful. We discuss the case and review the pertinent literature.
