A case of oropharyngeal injury associated with an unsuspected direct atlas anterior arch fracture is presented. Instability at the occipito-atlanto-axial joints developed because of the coexistence of a rather common congenital defect of the posterior atlas arch. Awareness of the frequency of congenital atlas anomalies and the possibility of direct cervical spine injury with pharyngeal trauma will aid early recognition of this problem and allow early effective treatment.
本文报告一例口咽损伤合并寰椎前弓隐匿性骨折的病例。由于寰椎后弓存在相当常见的先天性缺陷，枕寰枢关节出现不稳定。认识到先天性寰椎异常的发生率以及咽部创伤导致颈椎直接损伤的可能性，将有助于早期识别该问题并实现早期有效治疗。
