title: Endoscopic transnasal surgery in antrochoanal polyp.
abstract: The current treatment of antrochoanal polyp is simple avulsion of the nasal part with or without removal of the antral part. The antral part is removed through a Caldwell-Luc antrostomy, inferior meatal antrostomy, or middle meatal antrostomy. In this study, endoscopic surgery was performed in 22 cases of antrochoanal polyps where the antral part was removed through the middle meatus. Two new instruments were designed to help complete removal of the antral part of the polyp through the maxillary ostium. Some points of controversy concerning the antrochoanal polyp are discussed according to the diagnostic and therapeutic endoscopic findings. Endoscopic follow-up of these cases for periods ranging between 6 and 30 months, with an average of 20 months, showed no recurrence. It was concluded that endoscopic surgery of the antrochoanal polyp through the middle meatus could be performed as an outpatient procedure, and is safe and reliable.
