what is laryngomalacia
Laryngomalacia (literally, soft larynx ) is the most common cause of stridor in infancy, in which the soft, immature cartilage of the upper larynx collapses inward during inhalation, causing airway obstruction.n infantile laryngomalacia, the supraglottic larynx (the part above the vocal cords) is tightly curled, with a short band holding the cartilage shield in the front (the epiglottis) tightly to the mobile cartilage in the back of the larynx (the arytenoids). These bands are known as the aryepiglottic folds.
