[Congenital nasal pyriform aperture stenosis].
Obstruction of the nasal airway is potentially lethal in newborns because they are forced to breathe through their noses. The most common cause of obstruction is atresia of the choanae; however, other entities such as congenital nasal pyriform aperture stenosis, although rare, must be considered in the differential diagnosis of a newborn that shows signs and symptoms of upper airway compromise. We report two cases of nasal pyriform aperture stenosis seen at our center; we describe the main characteristics of the condition and review the relevant literature.
