Rupture of the trachea and major bronchi usually results from blunt trauma to the chest. To define the characteristics of the condition, the mechanism of injury, presentation and hospital course, the authors reviewed seven cases of tracheobronchial rupture after blunt trauma. Four were injured in a motor vehicle accident, two had a crush injury and one child had a fall from a playground swing. ⋯ Two patients died secondary to associated head injuries; one patient underwent repair of the bronchus intermedius and one patient had a lacerated membranous trachea. The possible mechanisms of injury are: rapid deceleration with forward swing of the trachea, widening of the transverse diameter of the chest, exerting traction on the carina, and a rapid rise of airway pressure on impact. Surgical intervention is recommended at an early stage to avoid loss of lung tissue.
