Choanal Atresia

Statistics on Choanal Atresia

The statistics on choanal atresia show that it is a rare birth defect occurring in one of every 5,000 to 8,000 births. Still, it is the most common nasal abnormality in newborn babies. More than twice as many girls as boys experience the condition. Other congenital problems affect more than half of infants with choanal atresia.
