title: [Two cases of tracheobronchial disruption due to blunt trauma].
abstract: Tracheobronchial disruption by blunt trauma is relative rate, but clinical course is various and sometimes fatal. A 22-year-old man (case 1) was admitted with traffic accident. Chest CT demonstrated pneumomediastinum and left pneumothorax. Bronchoscopy showed tracheal tear, but conservative therapy was selected because the peritracheal sheath remained intact. The second case was 27-year-old man, who was admitted with traffic accident. Pneumomediastinum and left tension pneumothorax were diagnosed, but bronchoscopy could not confirm the tracheobronchial disruption. As bronchial injury, lacerations and contusions of the lingular division were found in the thoracotomy, segmentectomy was carried out. When pneumomediastinum or pneumothorax is recognized in the patient of the blunt trauma, more careful examination of bronchoscopy is necessary to confirm the tracheobronchial disruption.
