Laryngomalacia literally means “Soft Larynx”. It is caused by floppiness of the laryngeal tissues above the vocal cords (the supraglottic larynx). With inspiration (breathing in), the tissues above the vocal cords fall in towards the airway and cause partial obstruction. This creates stridor (noisy breathing due to obstruction at the level of the voice box). Typically the folds of tissue between the front and back of the voice box (aryepiglottic folds) are shortened. This causes the epiglottis to curl inward (become “omega-shaped”) and causes the tissue over the cartilage in the back of the voice box (arytenoids) to suck into the airway.

Laryngomalacia is the most common cause of noisy breathing in infants. More than half of infants have noisy breathing during the first week of life, and most develop this by 2-4 weeks of age. Rarely, laryngomalacia occurs in older children, or adults, particularly those with other medical problems.
