Choanal Atresia: Embryologic Analysis and Evolution of Treatment, a 30‐Year Experience

Objectives: Choanal atresia (CA) is a congenital obstruction of the posterior nasal apertures. Multiple surgical techniques have been proposed to repair the atresia. The purpose of this study is to review the basic science and embryology of CA with emphasis on the senior author's extensive experience, and refinement of the treatment of CA. In addition, we will review the outcomes after surgical correction of pediatric patients with CA.
