[A rare cause of respiratory distress in the newborn].

C Cheping J Khamis

Rev Med Liege 2022 Jul;77(7-8):440-442

Service d'Imagerie médicale, CHC MontLégia, Liège, Belgique.

Respiratory distress in the newborn represents a real medical challenge from both the etiological and therapeutic points of view. The causes of respiratory distress are usually divided into two categories: upper and lower airway impairments, with the glottis as the reference level. Concerning the upper airway impairment in the newborn, nasal malformations are one of the main causes, choanal atresia in particular and more rarely congenital nasal pyriform aperture stenosis.
