稀有な喉頭外傷

抄録

A 21 year old female was injured in an automobile collision. She had a transient syncope at that time. Because of retrograde amnesia, she could not recall any injured sites except her buccal mucosa and bilateral knees. Thorough examination of the neck revealed no external sign of injury at that time. Approximately one month after the accident, she developed sudden dyspnea. Because of respiratory distress, an elective tracheotomy was performed. Direct laryngoscopy disclosed firm mass of granulation tissue in the glottic area. The larynx was explored by an external approach. Vertical fracture lines in both side of the thyroid alae were noted. It was noticed that the scar tissue was present between both vocal cords and almost obstructed the airway. By utilization of scar tissue, reconstruction of the glottis was done. A very satisfactory airway and voice were obtained. She was discharged on the fiftieth hospital day.
