Congenital subglottic web: a rare cause of neonatal stridor.

Laryngeal web is a rare malformation caused by an anomalous embryologic development of the primitive larynx. Most of the reported cases are of the glottic type; the subglottic web is extremely rare. Laryngotracheobronchoscopy plays an essential role in the diagnostic workup of this lesion, and endolaryngeal resection is the preferred treatment whenever a structural cartilaginous subglottic stenosis is not present. The authors present the case of a neonate with a subglottic web diagnosed soon after birth. Management of this rare entity is discussed.
