Eight patients with unilateral antrochoanal polyps underwent transnasal endoscopic surgery in recent 5 years. Their age ranged from 8 to 36 years. Three patients, were male and the others 5 were female. Both nasal and antral portion of antrochoanal polyps were removed through middle meatus under sinoscope. The antral mucosa surrounding the stalk of choanal polyps was removed with polyps as well. The post-operative follow-up period ranged from 13 to 47 mlonths. There was no recurrence of polyps in these 8 patients and all were symptom-free. We recommend transnasal endoscopic surgery is appropriate for management of antrochoanal polyps.
