ABSTRACT

Antrochoanal polyps are uncommon benign lesions with a slow growth; they usually develop as a unilateral pathology, more frequently diagnosed on the left side. They usually occur in children and young adults. They arise from maxillary sinus and pass through the natural maxillary ostium, or sometimes from the accessory ostium into the nasal cavity, and even reaching the choana and nasopharinx. Antrochoanal polyps are constituted from two components: the cystic and solid polypoid parts. The symptoms are unilateral or bilateral nasal obstruction, hyaline or mucopurulent discharge, and sometimes epistaxis. Diagnosis of antrochoanal polyps is demonstrated by computed tomography and magnetic resonance. There are two options of surgical treatment, the endoscopic approach as an isolated technique and the endoscopic approach combined with transcanine or Caldwell Luc access, in order to perform the curette of the maxillary sinus. We present three cases of antrochoanal unilateral polyps in male patients of pediatric age. They were treated by endoscopic surgery with intranasal polyp removal, middle meatal antrostomy, uncinectomy by debridation with maxillar sinus endoscopy, followed by debridation of the antral polypoid tissue. The evolution was satisfactory in two cases; however, one case had recurrence before one year postsurgery; this case was treated by flexible endoscope revision and debridation of the disease from the lateral wall of the maxillary sinus, with no recurrence.
