ABSTRACT

Choanal atresia is a congenital defect caused by persistence of the bucopharyngeal membrane. It may be uni or bilateral. Treatment consists in surgical opening of the choana. A retrospective review of patients operated for choana atresia between January 1990 and September 2007 was done. There were 7 patients; only 6 were included in this paper. The age at surgery varied from 1 month to 12 years; there were three boys. Bilateral atresia was present in 3 patients and unilateral in the other 3. Surgical procedure was transnasal microscopic approach in three of the patients, and endoscopic in the rest. Stenting was done in 5 patients in a first procedure. Post-surgical stenosis occurred in 4 patients. One patient required two surgical procedures, and one procedure in three patients to maintain permeability of the choana. We conclude that choanal atresia is a rare defect and that surgical outcome with the use of stents in our institution has favorable similar results to those reported in the literature.
