Laryngomalacia (Infantile)

Laryngomalacia (LM) is best described as floppy tissue above the vocal cords that falls into the airway when a child breathes in.

  • It is the most frequent cause of noisy breathing (stridor) in infants and children.
  • It is the most common birth defect of the voice box (larynx).
  • The cause and reason why the tissue is floppy are unknown. The part of the nervous system that gives tone to the airway is most likely underdeveloped.
