What is tracheobronchomalacia (TBM)?

In many cases, people with bronchomalacia also have tracheomalacia, which is a weakness in the tracheal walls. These two conditions together are called tracheobronchomalacia (TBM).

Like bronchomalacia, tracheomalacia can interfere with breathing and is more common in newborns. Tracheomalacia is often linked to a rare birth defect known as esophageal atresia.
