Tracheobronchomalacia (TBM) is a condition characterized by flaccidity of the tracheal support cartilage which leads to tracheal collapse. [1] This condition can also affect the bronchi. There are two forms of this condition: primary TBM and secondary TBM.
Other symptoms include exercise intolerance, respiratory distress, and gagging while eating or drinking. Tracheal collapse is easily seen on a radiograph as a narrowing of the tracheal lumen. Treatment for mild to moderate cases include corticosteroids, bronchodilators, and antitussives. Medical treatment is successful in about 70 percent of ...
Tracheomalacia is a condition or incident where the cartilage that keeps the airway (trachea) open is soft such that the trachea partly collapses especially during increased airflow. This condition is most commonly seen in infants and young children. [2] The usual symptom is stridor when a person breathes out. This is usually known as a ...

The most common tracheal injury is a tear near the carina or in the membranous wall of the trachea. [15] In blunt chest trauma, TBI occurs within 2.5 cm of the carina 40–80% of the time. [ 2 ] The injury is more common in the right main bronchus than the left, possibly because the former is near vertebrae , which may injure it. [ 2 ]
Bronchomalacia means 'floppiness' of some part of the bronchi. Patients present with noisy breathing and/or wheezing. There is collapse of a main stem bronchus on exhalation. If the trachea is also involved the term tracheobronchomalacia (TBM) is used. If only the upper airway the trachea is involved it is called tracheomalacia (TM). There are ...
The symptoms consist of dyspnea, wheezing, a nonproductive cough. [3] [4] Obstructive respiratory failure may develop as the result of either permanent tracheal or bronchial narrowing or chondromalacia with expiratory collapse of the tracheobronchial tree. [3] Endoscopy, intubation, or tracheotomy has been shown to hasten death. [3]
