Definition: TBM is defined as a condition in which there is weakness of tracheal and bronchial walls due to softening of the supporting cartilage and hypotonia of myoelastic elements.
EDAC (excessive dynamic airway collapse): Escessive bulding of the posterior membrane into the airway lumen during expiration that narrows the airway lumen by ≧50%. Atrophy of elastic fibers of the posterior menbrane can be associated with EDAC.
