Acquired tracheomalacia is a weakness and floppiness of the walls of the windpipe (trachea) that develops after birth.
See also: Congenital tracheomalacia
Acquired tracheomalacia is very uncommon. Rarely, babies, infants, and adults may develop the condition. It occurs when normal cartilage in the wall of the windpipe begins to break down.
Acquired, or secondary, tracheomalacia may result:
A physical examination confirms the symptoms. A chest x-ray may show narrowing of the trachea when breathing out. Even if the x-ray is normal, it is needed to rule out other problems.
A procedure called a laryngoscopy is used to diagnose the condition. This procedure allows the otolaryngologist (ear, nose, and throat doctor, or ENT) to see the structure of the airway and determine how severe the problem is.
Other tests that may be performed include:
The condition may improve without treatment, but persons with tracheomalacia must be monitored closely when they have respiratory infections.
Aspiration pneumonia 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. It can become an urgent or emergency condition.
