چکیده
Antrochoanal polyps usually present unilaterally. It is defined as a polyp originating in the maxillary sinus, protruding in the middle meatus through the ethmoidal infundibulum or an accessory ostium and further extends posteriorly through the choana into the nasopharynx or in oropharynx in a few cases. An antrochoanal polyp usually has three parts according to its extension, i.e antral, nasal and choanal part. It is seen commonly in children and in both males and females. Exact etiology is not known but probably chronic infection of the maxillary sinus may be one of the factors in pathogenesis of AC polyps. Antrochoanal polyp presenting in both nasal cavities simultaneously is very rare occurrence.
