Tracheomalacia is a condition in which the walls of the trachea are very weak or soft. The trachea, also called a windpipe, is a tube made of muscles and cartilage. Rings of cartilage support the windpipe and keep it open during breathing. In tracheomalacia, the windpipe may be so weak that it collapses and may block the airway.
Tracheomalacia is most common in infants and small children. Most of the time it is a birth defect. However, tracheomalacia may also develop in:
Symptoms of tracheomalacia include loud noisy breathing (stridor) and a loud barking cough. Your child may wheeze constantly, and be worse when crying, feeding, or coughing.

Most babies with this disorder seem happy and do not seem to be struggling when they wheeze. The wheezing does not improve when the baby is given medicines such as bronchodilators or anti-inflammatory drugs.
If tracheomalacia is severe, the child may struggle very hard for breath. Over time, the chest wall may become deformed. Babies may not be able to breathe and eat at the same time, and may not gain weight properly. If the airway is severely collapsed or blocked, the baby needs to be on oxygen.

If the condition is severe, does not improve, or causes growth problems, your child may need:
