Abstract:
Congenital nasal pyriform aperture stenosis (CNPAS) is an unusual cause of upper respiratory obstruction in neonates and infants. The diagnosis is made with Computed Tomography (CT) of nasal cavity when maximum transverse diameter of the pyriform aperture is less than 11 mm. We present a patient with breathing difficulty since birth. The diagnosis of CNPAS was made after a CT examination of the nasal cavity. We also discuss typically associated abnormalities.
