식도 손상 없이 발생한 후두 관통상 1예

Acute laryngotracheal trauma is life-threatening and overlooked by little experience of clinician because it is uncommon. Main presenting symptoms and signs are hoarseness, vocal fold injury, soft tissue contusion or superficial mucosal laceration, cricoarytenoid dislocation, thyroid fracture, epiglottic fracture and mixed injury. Early diagnosis is important for appropriate progonosis. Surgical treatment is varied depending on the severity of injury. We report a interesting case of patient with penetrating laryngeal trauma without esophageal injury. (J Clinical Otolaryngol 2005;16:293-297)
