The antrochoanal polyp.

The antrochoanal polyp is a particular pathology of nasal fossae and sinuses. Since the first description made by Killian, several pathogenic mechanisms and surgical techniques have been reported. The polyp exeresis is classically made using the Caldwell-Luc approach. The aim of our study is to lay stress on the interest of endonasal surgery compared to other surgical procedures. Between 1996 and 1998, we operated on 12 cases by endonasal approach. Diagnosis is made upon clinical, CT-scan and pathological data. In all cases, an extended middle meatotomy is performed. In 3 cases, it is associated with an inferior meatotomy. The polyp pedicle is systematically coagulated at level of its maxillary implantation area. No recurrence, nor operative complication are noted. The average follow-up is 12 months.
