Antrochoanal polyps (APs) are benign lesions originating from the mucosa of the maxillary sinus and capable of extending to the choana and nasopharynx [1]. Although the first case was reported by Palfyn in 1753, it was first described in detail by Killian [2,3]. APs constitute 4-6% of adult polyps and 33% of childhood polyps. The most common symptom is unilateral nasal obstruction. Other symptoms include rhinorrhea, sinusitis and snoring [4].
