Acquired Tracheomalacia: Causes, Symptoms, and Treatment
Medically reviewed by Harsha Moole, MD, Internal Medicine. Last reviewed: October 2, 2026.
What kind of doctor treats Acquired Tracheomalacia?
A pulmonologist, a doctor who specializes in lung and airway diseases, usually treats acquired tracheomalacia and can perform bronchoscopy and manage treatment. A thoracic surgeon may be involved if surgery is considered. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Acquired tracheomalacia is a condition in which the windpipe, or trachea, becomes weak and floppy because the cartilage rings that normally hold it open lose their stiffness, allowing partial collapse. The word "acquired" means the problem develops after birth, unlike the congenital form present from birth.
Symptoms
Symptoms can come on slowly and are sometimes mistaken for asthma. Common symptoms include noisy, high-pitched breathing when breathing out, a lingering cough, trouble clearing mucus, and repeated chest infections, often worse with activity or when lying flat. Severe narrowing needs prompt medical care.
Causes and who gets it
Anything that damages or presses on the windpipe can lead to acquired tracheomalacia. Long-term use of a breathing tube, called intubation, can injure the cartilage rings. Chest injuries, airway surgery, pressure from a growth or blood vessel, and chronic inflammation from infections or chronic bronchitis can contribute.
How doctors diagnose it
Doctors start with a medical history and physical exam. A CT scan can show whether the windpipe narrows during breathing. The most direct test is bronchoscopy, which uses a thin, flexible tube with a camera to see the airway walls collapse in real time.
Treatment
Treatment depends on severity and cause. Mild cases may need only watchful waiting and treatment of the cause, such as quitting smoking. For more bothersome symptoms, doctors may recommend a CPAP machine to hold the airway open. In severe cases, surgery may be an option, such as a tracheal stent to keep the windpipe open.
When to see a doctor
See a doctor for a lasting cough, noisy breathing, or shortness of breath that does not go away. Get urgent care if you are struggling to breathe, turning blue around the lips, or cannot speak in full sentences. Repeated chest infections also deserve a medical visit.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance per visit, while a concierge doctor usually charges more and often works alongside insurance. Either can be a helpful first stop with longer appointments, and will refer you to a pulmonologist if tracheomalacia is suspected.
Common questions
Is acquired tracheomalacia dangerous?
It depends on how severe it is. Many people have mild symptoms that are manageable. Severe collapse of the windpipe can cause serious breathing trouble. A doctor can measure how much the airway narrows and explain what your case involves.
Can it go away on its own?
Sometimes mild cases improve when the underlying cause is treated, such as healing after a breathing tube is removed. More established cartilage weakness usually does not reverse on its own.
How is it different from asthma?
Asthma is a narrowing of the small airways in the lungs from inflammation. It often responds to inhaler medicines. Tracheomalacia is a floppiness of the main windpipe itself. Inhalers usually do not fix it. Testing helps doctors tell the two apart.
Does smoking make it worse?
Smoking causes long-term airway inflammation and coughing. This can strain a weakened windpipe. Quitting smoking is usually part of treatment for any airway condition. A doctor can suggest ways to help you stop.
