Answer

Answer a.

Choanal atresia has an incidence of 1 in 7000 live births and a bony obstruction is present in 90% of cases. Infants are obligate nose breathers at rest, but symptoms may improve with crying (mouth breathing). Unilateral disease may not be diagnosed until later in life. Choanal atresia is part of the CHARGE association, thus patients should be assessed for other anomalies.
