We report a case of cricoid cartilage fracture with unilateral arytenoid dislocation following a motorcycle accident. This 25 year old male sustained blunt injury to the head, face and neck. He presented late to the hospital with one week history of dysphonia. Laryngoscopy revealed cadaveric position of the non-functioning left vocal cord. CT and MRI showed laterally displaced left vocal cord. Displaced fractures were noted in the cricoid at the junction of lamina with the anterior arch on the left side and at the right side of the anterior arch, along with dislocated left arytenoid resulting in ipsilateral vocal cord palsy. Medialization thyroplasty was performed to improve his phonation. Laryngeal trauma warrants close monitoring because of the risk of airway compromise. Radiologists play a crucial role in early diagnosis and should always have high index of suspicion. Recognition of laryngeal injury is important for initial resuscitation as well as for long term airway and vocal function.
我们报告一例摩托车事故后环状软骨骨折伴单侧杓状软骨脱位的病例。该25岁男性头部、面部和颈部遭受钝器伤。他在受伤一周后因声音嘶哑才到医院就诊。喉镜检查显示左侧声带呈尸位，无功能。CT和MRI显示左侧声带向外侧移位。在环状软骨左侧板与前弓交界处以及前弓右侧可见移位骨折，同时左侧杓状软骨脱位，导致同侧声带麻痹。行甲状软骨内移成形术以改善其发声。由于存在气道受损风险，喉外伤需要密切监测。放射科医生在早期诊断中起着关键作用，应始终保持高度怀疑指数。认识到喉损伤对于初始复苏以及长期气道和发声功能都很重要。
