Choanal atresia
Choanal atresia (CA) is a congenital obstruction of the posterior nasal apertures. Multiple surgical techniques have been proposed to repair the atresia. The first repair of choanal atresia is the one most likely to succeed. Choanal atresia can be unilateral or bilateral. The nasal endoscopic technique is the favored technique. It has the advantages of a low restenosis rate, does not violate the palate, and does not cause the cross-bite and palate arch deformities seen in the transpalatal technique.
