Choanal atresia, bilateral – http://id.who.int/icd/entity/1138913171
Bilateral choanal atresia is a congenital anomaly of usually sporadic origin (but some familial cases have been reported), more commonly seen in females than in males (2:1), where the nose is blocked on both sides by bony or soft tissue formed during embryological development and is characterised by respiratory distress relieved by crying and rhinorrhoea that presents at birth.
