Laryngomalacia (LM) is the most common cause of congenital stridor. It is caused by obstruction of the upper airway by collapse of redundant supraglottic tissues during inspiration. In the management of a child with congenital stridor, it is important to rule out other malformations of the upper airway that could mimic or be synchronous with LM. Symptoms of LM are usually mild and disappear spontaneously by 2 years. About 20% of patients with LM may have extreme symptoms (severe stridor, feeding difficulties and growth retardation) requiring treatment by endoscopic surgery (supraglottoplasty), which has an excellent success rate with little risk of recurrence and complications.
