We present a four days old newborn with noisy breathing and worsening respiratory distress. The baby was managed with high humidified flow nasal cannula. Computed tomography confirmed congenital pryiform aperture stenosis and was managed surgically. Failure of passage of infant feeding tube through nares CNPAS needs to be kept in mind. Diagnosis and treatment of unilateral nasal pyriform stenosis is vital and can be life saving.en-UScongenital nasal pyriform aperture stenosispassage of infant feeding tubechoanal atresiaaperture dilatationsublabial approachArticle
