Nasal airway obstruction in the newborn or infant can be a life-threatening condition.

Two cases of congenital bony stenosis of nasal pyriform aperture are presented. Both were managed conservatively. Computed tomography demonstrated in detail the underlying anatomical abnormality and allowed its proper differentiation from choanal atresia.
