Pak J Med Health Sci Jan ;5(1):162-4.

Objective: To evaluate the effectiveness of endoscopic excision of the antrochoanal polyp and its role in decreasing the recurrence rate. Design: Retrospective. Methods : Medical records of sixty patients with antrochoanal polyp (ACP) diagnosed and treated at Mayo Hospital Lahore between March 2001-September 2004 were retrospectively studied. Results: Out of sixty patients,42 were male and their ages ranged from 6 to 45 years with a mean age of 17.37 years. Nasal obstruction was the most common presenting symptom. Endoscopic endonasal removal of ACP was performed in all 51 patients as primary surgery. Revision endoscopic removal was done in nine patients. All candidates had follow up from nine to 42 months with mean average time of 24 months. Recurrence was confirmed in three patients after primary surgery and in none after revision surgery. Conclusion: Endoscopic approach compared to previous modalities of treatment has the capability to ensure complete removal of the ACP and decrease its rate of recurrence.
