    Abstract:
    Laryngotracheal trauma is life-threatening. We identified 23 patients between 1992 and 1998 with laryngeal (12), tracheal (8), and combined injuries (3). Nineteen patients had penetrating trauma (gunshot wound, 12; stab wound, 7), and four patients had blunt injury. Flexible laryngoscopy identified the injury in 8 of 12 patients (75%), and computer tomography scan was positive in 9 of 9 patients (100%). Twelve of the 19 patients with penetrating wounds were managed by primary repair, 4 had endotracheal intubation without surgical repair, and 3 were observed. No patient with a blunt tracheal injury required repair. Two had endotracheal intubation, and two were observed. A high index of suspicion is essential to identifying laryngotracheal injury. Computer tomography scan is a sensitive diagnostic test for laryngotracheal injury, and may be indicated despite normal flexible laryngoscopy. The decision to repair injuries or observe injuries is primarily based on respiratory distress and associated injuries.
