Congenital nasal pyriform aperture stenosis

Congenital nasal pyriform aperture stenosis is a rare form of nasal obstruction and must be distinguished from other causes of nasal obstruction. It should be considered in the differential diagnosis of any neonate or infant with signs and symptoms of upper airway compromise. Diagnosis is made on the basis of clinical examination and computerized tomography findings, while treatment often involves surgical enlargement of the bony nasal inlet.
