Learn About Acquired Tracheomalacia
Acquired tracheomalacia is a weakness and floppiness of the walls of the windpipe (trachea, or airway). It develops after birth.
Congenital tracheomalacia is a related topic.
Secondary tracheomalacia
Acquired tracheomalacia is very uncommon at any age. It occurs when normal cartilage in the wall of the windpipe begins to break down.
This form of tracheomalacia may result:
- When large blood vessels put pressure on the airway
- As a complication after surgery to repair birth defects in the windpipe and esophagus (the tube that carries food from the mouth to the stomach)
- After having a breathing tube or trachea tube (tracheostomy) for a long time
Symptoms of tracheomalacia include:
- Breathing problems that get worse with coughing, crying, or upper respiratory infections, such as a cold
- Breathing noises that may change when body position changes, and improve during sleep
- High-pitched breathing
- Rattling, noisy breaths
The condition may improve without treatment. However, people with tracheomalacia must be monitored closely when they have respiratory infections.
Adults with breathing problems may need continuous positive airway pressure (CPAP). Rarely, surgery is needed. A hollow tube called a stent may be placed to hold the airway open.
Aspiration pneumonia (a lung infection) can occur from breathing in food.
Adults who develop tracheomalacia after being on a breathing machine often have serious lung problems.
Call your health care provider if you or your child breathes in an abnormal way. Tracheomalacia can become an urgent or emergency condition.
