Abstract
Antrochoanal polyp also called Killian Polyp is an inflammatory polyp, which arises from within the maxillary sinus, and prolapses in to the nasal cavity through the accessory ostium of the maxillary sinus. This polyp grows backwards towards the posterior choana. It is a unilateral benign lesion common in children and rare among adults.
Antrochoanal polyps are diagnosed clinically with diagnostic nasal endoscopy and CT scan of paranasal sinus helps in analyzing the extent of lesion and in ruling out other differential diagnosis of a unilateral nasal mass. The gold standard modality of treatment is functional endoscopic sinus surgery with complete removal of the polyp by dissecting out all the attachments of the polyp from within the maxillary sinus and widening of the obstructed ostium. The typical histological features are characterized by presence of cystic component, infiltration of inflammatory cells and edema. The choanal portion shows presence of fibrosis and squamous metaplasia. This is a case report of an adult patient with antrochoanal polyp.

Key words: Antrochanal polyp, adult, Unilateral
