An infant can learn to mouth breathe, which can delay the need for immediate surgery.
Surgery to remove the obstruction cures the problem. Surgery may be delayed if the infant can tolerate mouth breathing. The surgery may be done through the nose (transnasal) or through the mouth (transpalatal).
Full recovery is expected.
Possible complications include:
Choanal atresia, especially when it affects both sides, is generally diagnosed shortly after birth while the infant is still in the hospital. One-sided atresia may not cause symptoms, and the infant may be sent home without a diagnosis.
If your infant has any of the problems listed here, consult your health care provider. The child may need to be checked by an ear, nose, and throat (ENT) specialist.
