[edit] Discussion of Tracheobronchomalacia

  • Tracheobronchomalacia is characterized by weakness of the tracheal walls and supporting cartilage.
  • Primary tracheobronchomalacia is a congenital weakness that presents at birth
  • Secondary or acquired tracheobronchomalacia is associated with prior intubation or radiation and a history of tumors and chronic obstructive pulmonary disease.
  • Previous surgery and a history of tracheoesophageal fistula are also recognized risk factors for the development of tracheobronchomalacia.


  • Recent clinical data suggest that in patients presenting with chronic cough, tracheobronchomalacia is the third most common cause after asthma and gastroesophageal reflux.
  • Symptoms are nonspecific; include cough, wheezing, and dyspnea; and are often misinterpreted as asthma.
