Abstract

The congenital nasal piriform aperture stenosis (CNPAS) is a rare cause of neonatal airway obstruction and could be easily mistaken as the choanal stenosis or atresia. The piriform aperture is a term used to refer to the anterior nasal openings. The nasal airway obstruction in the neonate can result in respiratory difficulties and may be going to life threatening consequences. Computed tomography demonstrates in detail the underlying anatomic abnormalities which allows differentiation of the CNPAS from other upper airway abnormalities. We reported a case of CNPAS, a 1-month-old male infant presented with respiratory difficulties. Shortly after birth, he had mild respiratory difficulties and there was difficulty passing a nasal catheter intranasally. But he was improved through only conservative management and discharged at the age of 5 days. At the age of 1 month, CT scan revealed bilateral CNPAS.
