[Two cases of tracheal injuries secondary to blunt trauma].

We present two cases of injury to the cervical trachea and the tracheal bifurcation due to blunt trauma. A 20-year-old man sustained complete disruption of the cervical trachea during a traffic accident. He underwent end-to-end anastomosis of the disrupted trachea. Nevertheless, 3 weeks after the initial surgery, tracheostomy was required because of suture failure. Two months after the second procedure, he underwent closure of the tracheostoma. Granulation developed temporarily, but diminished thereafter. The second case was a 14-year-old boy. He sustained a longitudinal laceration about 3 cm from the tracheal over the membranous portion during a traffic accident. The laceration was successfully repaired by interrupted sutures with absorbable materials. Our experiences emphasize the importance of debridement of the injured cartilageous portion during treatment of tracheal injury due to blunt trauma and the difficulty in managing complete disruption of the cervical trachea with bilateral paralysis of the recurrent nerve.
