INFORMATION FROM CHILDREN"S HOSPITAL PRINTOUT
Laryngomalacia is thought to be a birth defect that involves a delay in the maturing of the voice box (larynx). This delayed growth makes the cartilage of the larynx "floppy" There is a lack of the normal ridge support of the larynx. When baby breathes in, there is a partial collapse of the structures of the larynx and a narrower breathing passage. The partial blockage is the source of the noise with breathing. Symptoms usually resolve between 12 to 24 months and most children eventually improve without treatment.
