Congenital nasal pyriform aperture stenosis is a rare cause of neonatal airway obstruction. Computed tomography confirms the diagnosis and delineates the anomaly. This abnormality can be isolated or associated with abnormalities of the midface. The two options are surgical or medical treatment. The surgical treatment usually used is a surgical enlargement of the nasal pyriform aperture via a sublabial approach. We report 2 cases of congenital nasal stenosis treated successfully by an inter-maxillary disjunction followed by an expandable palatal plate. This simple and low morbidity technique allowed a durable transversal augmentation of the pyriform apertures.
