Findings

No curated finding names choanal atresia, bilateral yet. Everything below is reference data from Mondo, HPO and GenCC, not evidence about what affects it.

Definition

Bilateral choanal atresia is a congenital anomaly that is usually sporadic (but some familial cases have been reported), is more commonly seen in females than in males (2:1), and where the nose is blocked on both sides by bony or soft tissue formed during embryological development. It is characterized by respiratory distress relieved by crying and rhinorrhea that presents at birth.
