Choanal atresia refers to a lack of formation of the choanal openings.
It can be unilateral or bilateral. It frequently presents in neonates where it is one of the commonest causes of nasal obstruction in this age group. There is a recognised female predilection. Presentation depends on whether it is uni- or bilateral. Unilateral choanal atresia presents late and can be asymptomatic or present with rhinorrhoea.
Bilateral atresia can present with neonatal respiratory distress as infants are obligate nose breathers. Another finding is failure to pass a nasogastric tube.
