ZANETTA, Adrián; RODRIGUEZ, Hugo; CUESTAS, Giselle  y  TISCORNIA, Carlos. Stertor in the newborn due to congenital nasal pyriform aperture estenosis: case series. Arch. argent. pediatr. [online]. 2010, vol.108, n.6, pp.552-555. ISSN 0325-0075.

Stertor is a noise generated by the disturbance of the air flow passing through the nose. Its main cause -in newborns and infants- is inflammatory or infectious rhinitis. Congenital, neoplastic, traumatic or iatrogenic causes are less frequent. Congenital stenosis of the pyriform aperture is a rare etiology of nasal obstruction in the neonates. Early diagnosis and appropriate treatment are essential because of their exclusive nasal breathing. Suspicion might arise when a difficulty or even an impossibility to pass a probe of 2.8 mm (K30 tube) through anterior nares, exists. Diagnosis should be confirmed by a computed tomography of the craniofacial massif. The therapeutic behavior will depend on the severity of symptoms. We describe our experience with nine patients with this condition whose surgical correction was successful.
