Short answer · Medically reviewed summary · Last updated: 2026-05-08
Tracheobronchomalacia is characterized by the excessive collapse of the airway walls during breathing, typically manifesting as chronic cough, shortness of breath, and a persistent "barking" sound. If you suspect you have Tracheobronchomalacia, persistent respiratory symptoms that do not respond to standard asthma or COPD treatments should prompt a specialized evaluation by a pulmonologist. What are the early signs of Tracheobronchomalacia? The primary hallmark of Tracheobronchomalacia is airway instability, which leads to dynamic collapse during exhalation.

Tracheobronchomalacia is characterized by the excessive collapse of the airway walls during breathing, typically manifesting as chronic cough, shortness of breath, and a persistent "barking" sound. If you suspect you have Tracheobronchomalacia, persistent respiratory symptoms that do not respond to standard asthma or COPD treatments should prompt a specialized evaluation by a pulmonologist.
What are the early signs of Tracheobronchomalacia?
The primary hallmark of Tracheobronchomalacia is airway instability, which leads to dynamic collapse during exhalation. Early indicators often include a chronic, brassy, or barking cough that is difficult to treat, difficulty clearing secretions, and a noticeable wheeze or stridor that occurs specifically during expiration. Many of the 41 members in our DiseaseMaps community report that symptoms worsen during physical exertion, laughing, or coughing fits.
How do I differentiate normal breathing from Tracheobronchomalacia?
While occasional coughing or mild breathlessness is common, Tracheobronchomalacia involves a mechanical structural weakness. You should consider tracking these patterns:
- A cough that sounds mechanical or "croup-like" rather than typical bronchial congestion.
- Shortness of breath that feels like an obstruction rather than a lack of air in the lungs.
- Symptoms that are consistently triggered by forced exhalation (like coughing or straining).
- A lack of significant improvement after using standard asthma inhalers.
When should I seek urgent medical evaluation?
If you experience "red flag" symptoms, please seek emergency care immediately. These include cyanosis (bluish tint to lips or skin), severe respiratory distress, an inability to speak in full sentences, or fainting spells following a severe coughing fit, which can occur in advanced Tracheobronchomalacia.
How is Tracheobronchomalacia diagnosed?
To investigate Tracheobronchomalacia, ask your doctor about a dynamic airway evaluation. Standard resting CT scans often miss this condition because they do not capture the airway during forced breathing. Request a dynamic expiratory CT scan or a flexible bronchoscopy, which allows a physician to visualize the airway collapse in real-time. If your concerns are dismissed, ask for a referral to a center specializing in airway disorders or thoracic surgery.
