title: [Antrochoanal polyps: diagnosis and management].
abstract: Antrochonal polyp is a unilateral and benign tumor of the maxillary sinus occurring in children. Its physiopathology remains unclear. Nasal presenting symptoms are unilateral obstruction and nasal discharge. In rare cases, presenting symptoms may be atypical. Radiographic examination with CT-scan and more rarely MRI helps the diagnosis. Surgery remains the mainstay of treatment and the endoscopic approach should be used in first intention. Double maxillary meatotomy by endoscopic approach procures a good exposure and permits a complete resection of the pedicle of the polyp. The insertion of the pedicule should be coagulated. In cases with recurrence or in cases of incomplete resection, an external approach (Caldwell-Luc) should be preferred.
