How is Bronchomalacia diagnosed?

Bronchomalacia is primarily diagnosed through dynamic airway evaluation, with flexible fiberoptic bronchoscopy serving as the gold standard for visualizing airway collapse during respiration. Because symptoms often mimic common respiratory conditions, the diagnosis of Bronchomalacia frequently requires a multidisciplinary approach to confirm the structural weakness of the bronchial walls.

How is Bronchomalacia diagnosed?

The diagnostic process for Bronchomalacia usually begins with a thorough clinical history focusing on chronic cough, wheezing, or recurrent respiratory infections. Since Bronchomalacia involves the softening of airway cartilage, physicians must observe the airway while the patient is breathing spontaneously. The following diagnostic tools are commonly utilized:

• Flexible Fiberoptic Bronchoscopy: The definitive test to visualize the dynamic collapse of the bronchial walls during expiration.


• Dynamic CT Scan (Expiratory CT): A non-invasive imaging technique that can capture airway narrowing during forced expiration.


• Pulmonary Function Tests (PFTs): Used to assess lung volumes and flow patterns, often showing an obstructive pattern in patients with Bronchomalacia.

What is the diagnostic odyssey like for this condition?

Patients often experience a long "diagnostic odyssey" because the symptoms of Bronchomalacia—such as persistent wheezing—are frequently misdiagnosed as asthma or chronic bronchitis. It is common for individuals to endure months or years of ineffective treatments before a specialist identifies the structural nature of their airway issues. If your initial primary care physician or generalist is unfamiliar with Bronchomalacia, seeking a pediatric or adult pulmonologist with specific experience in airway disorders is essential to prevent further delays.

Which conditions are confused with Bronchomalacia?

Differential diagnosis is critical because Bronchomalacia shares clinical features with several other conditions. Clinicians must rule out asthma, tracheomalacia, foreign body aspiration, extrinsic airway compression (like vascular rings), and bronchiectasis. Distinguishing Bronchomalacia from these conditions requires specialized expertise, as the treatment paths differ significantly.

Next steps

• Consult a board-certified pulmonologist who specializes in interventional bronchoscopy or airway disease.


• Keep a detailed symptom diary to help your specialist distinguish between asthma-like wheezing and the structural collapse seen in Bronchomalacia.
