Transnasal repair of congenital choanal atresia

Choanal atresia is a relatively rare congenital nasal anomaly that must be repaired to allow infants to adequately breathe and feed. Techniques used in repair have evolved with the development of high-quality optical equipment, such that an endoscopic approach is now most commonly employed. Operative adjuncts include lasers, topical steroids, and stenting. Restenosis is common in the first few years, but this can be improved with dilation.
