Abstract

Choanal atresia occurs in about 1 in 5000 births and is associated with other structural and genetic abnormalities. Choanal atresia is usually diagnosed postnatally due to respiratory distress, and rarely diagnosed antenatally. Here, a woman with severe polyhydramnios is described, whose fetus was diagnosed antenatally with isolated bilateral choanal atresia, as evident by persistent absence of flow through the nostrils on ultrasound. A literature review is presented of the antenatal findings of choanal atresia, using ultrasound and other imaging modalities. An association of choanal atresia with polyhydramnios should be considered. Examining flow through the fetal nose, using color Doppler, might aid in diagnosing choanal atresia. If this condition is suspected, a detailed ultrasound scan should be done to rule out other anomalies. Fetal magnetic resonance imaging has been suggested as an additional imaging tool in selected patients. Genetic counselling and invasive prenatal testing should be offered.
