Tracheomalacia is excessive trachea collapse, usually upon expiration. Severe symptoms accompany congenital types. Often milder versions occur following the neonatal period. Adult malacia is mostly linked to pulmonary chronic obstruction. There's still no standardized functional bronchoscopy. Dynamic CT airway is an excellent diagnostic tool. Bronchoscopy and stent insertion led to a major improvement, although with a high incidence of complication. Surgical lateropexia, excision of trachea and external surgical stabilization are possibilities. Aortopexy is the most common operation in children.
