Overview
In 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; they create the movements that opens and closes the vocal cords for phonation. The shortened aryepiglottic folds cause the epiglottis to be curled on itself. This is the well known “omega shaped” epiglottis in laryngomalacia.
