下颌运动受限是由许多原因引起的一种症状。最常见的为各种局部原因引起,其中多为对颧骨的损伤,造成下陷压迫,妨碍喙突运动或引起骨间粘连。然而无外伤的病例也可能存在喙突运动障碍。作者报告了一例双侧喙突增生引起下颌运动严重受限的病例并对该病的文献进行了复习。 Limited mandibular movement is a symptom of many causes. The most common cause for a variety of local causes, most of them for the damage to the cheekbones, causing subsidence oppression, obstructing the coracoid process or causing interosseous adhesions. However, non-traumatic cases may also have coracoid dyskinesia. The authors report a case of severe mandibular movement that is associated with bilateral coracoidosis and review the literature on the condition.
