Tracheomalacia synonyms

Tracheomalacia is a condition characterized by excessive flaccidity of the tracheal support cartilage, which leads to airway collapse during breathing. While commonly referred to as tracheomalacia, it is also clinically identified by terms reflecting its anatomical extent, such as tracheobronchomalacia, or by its developmental origin, such as primary or secondary tracheomalacia.

What are the common synonyms and related terms for Tracheomalacia?

In medical literature, you may encounter several terms used interchangeably with tracheomalacia depending on the location of the airway weakness. When the condition extends into the bronchi, it is referred to as tracheobronchomalacia (TBM). Historically, clinicians sometimes used descriptive terms like "flaccid trachea" or "soft trachea," though these are rarely used in modern formal documentation. Because tracheomalacia can be congenital or acquired, medical records may also specify the type to clarify the clinical presentation.

Why are there multiple names for this condition?

The nomenclature for tracheomalacia has evolved as diagnostic imaging, such as dynamic CT scans and bronchoscopy, has become more precise. The condition is often classified based on the underlying etiology or the anatomical involvement:

• Primary Tracheomalacia: Congenital weakness of the tracheal cartilage rings.


• Secondary Tracheomalacia: Caused by external compression (e.g., vascular rings or cysts) or prolonged intubation.


• Tracheobronchomalacia (TBM): Indicates that both the trachea and the bronchial airways are affected.

How is Tracheomalacia classified in medical databases?

Official medical coding systems provide specific identifiers to ensure consistency in research and clinical care. In the International Classification of Diseases (ICD-10/11), tracheomalacia is generally categorized under congenital malformations of the trachea or acquired disorders of the respiratory system. The Orphanet identifier for congenital tracheomalacia is ORPHA:86828, which helps researchers track this specific rare condition globally. Clinicians currently prefer using the term tracheomalacia or tracheobronchomalacia to ensure accurate communication between pediatric and adult specialists.

Next steps

• Consult a pediatric or adult pulmonologist to confirm the specific type of tracheomalacia affecting your airway.
