Endoscopic surgery in pediatric recurrent antrochoanal polyp, rule of wide ostium

Endoscopic wide middle meatal antrostomy is a useful and easily applicable technique to manage recurrent antrochoanal 3 polyp in children. Managing associated pathology as turbinate hypertrophy, associated adenoids, anterior ethmoidectomy, uncinectomy and endoscopic limited septoplasty should be put in mind in order to improve ventilations. Powered instrumentations, angled endoscopes (45 and 70°) and angled instrumentations can assure complete clearance of the polyp by identifying the origin of polyp in maxillary antrum.
