- Tracheobronchomalacia and/or Excessive Dynamic Airway Collapse? Karlıkaya, Celal; Alıcıoğlu, Banu // Balkan Medical Journal;Mar2011, Vol. 28 Issue 1, p104
Expiratory airway collapse is defined as more than 50% reduction in the horizontal cross-sectional area of the airway at expiration or during coughing; and is due to pure tracheobronchomalacia (TBM) or excessive dynamic airway collapse (EDAC). It is not easy to make a clear differentiation...

Tan, Judith; Ditchfield, Michael; Freezer, Nicholas // Pediatric Radiology;Aug2012, Vol. 42 Issue 8, p906
Tracheobronchomalacia is characterised by excessive airway collapsibility due to weakness of airway walls and supporting cartilage. The standard definition requires reduction in cross-sectional area of at least 50% on expiration. However, there is a paucity of information regarding the normal...
