Obstrucción nasal congénita por estenosis de la apertura piriforme. Serie de casos

Congenital nasal obstruction due to pyriform aperture stenosis. A case series Abstract Nasal obstruction in neonates is a potentially fatal condition due to their exclusive nasal breathing. The main cause is inflammatory or infectious rhinitis. Congenital, neoplastic, traumatic or iatrogenic causes are less frequent. Choanal atresia is the most common congenital nasal anomaly. A less common etiology of congenital nasal obstruction is pyriform aperture stenosis. Suspicion might arise in any newborn with varying degrees of stridor and respiratory distress, associated with the difficulty of passing a probe through anterior nares. Diagnosis should be confirmed by a computed tomography of the craniofacial massif. The therapeutic approach will depend on the severity of symptoms. We describe our experience with 5 patients with this condition, treated surgically using a sub-labial approach, and followed by nasal stenting. © 2013 Asociacion Espade Pediatria.
