AbstractLaryngotracheal injuries are serious complications in the case of penatrating neck trauma which may not commonly in Japan. In the last several decades, many authors have discussed method for accurate evaluation and immediate airway management for patient with laryngotracheal injury. But, standardization of the treatment is still controversial about mandatory exploration or selective exploration. We report 4 cases with fresh laryngotracheal injury due to penetrating neck trauma including 3 suicide attempt patients. In these cases, laryngotracheoplasty used by absorbable material was performed within 8 hours after trauma. Two cases of suicide attempt patients underwent tracheostomy at the lower level of the laryngotracheal injury. After these treatment, fiberoptic bronchoscopy was performed to evaluate the airway for 3 cases except 1 who was dead because of hemorrhagic shock on arrival. In 2 cases, the suture filament existed in the lumen of the larynx and trachea, there were no major granulation in the site of repairment and no infection. Three cases were extubated successfully and discharged without major airway problem. Two cases have psychiatric disease such as depression, so we must consider their psychiatric background in the future. In conclusion, penetrating laryngotracheal trauma, we should consider that serious airway injury may be hidden under the superficial small wounds. Also, rapid local wound exploration and laryngotracheoplasty is important for life-saving, and fiberoptic bronchoscopy is effective to prevent early respiratory complications and has value in the evaluation.
