[Complete disruption of cervical trachea, whose distal airways were migrated into the mediastinum].

The first case was a 55-year-old man, who suffered by a rope while driving his motor bicycle. On 7th day after injury, tracheotomy was scheduled due to progressive dyspnea. Following intubation of a endotracheal tube, his trachea was ruptured. The second case was a 16-year-old man, who was stabbed his trachea with a sword by his mother. His trachea completely separated following coughing during the examination of bronchoscopy. For 2 cases, we immediately excised their necks for tracheotomy but couldn't find their distal portion of trachea, because they were migrated into the mediastinum. We inserted our finger into the mediastinum for exploration and could draw it back. Both case's postoperative course was uneventful. Whenever cervical trachea is completely separated, tracheal distal end may be pulled down into the mediastinum. We invited new technique of exploration for migrated trachea using our finger.
