A heretofore unreported type of facial fracture is discussed. Twenty-two cases of posterior maxillary wall fracture are reviewed, of which 59% demonstrated concomitant mandibular fracture. The proposed mechanism for this injury is an impact from the ipsilateral mandibular coronoid process striking the posterior maxillary wall, with associated mandibular dislocation or fracture. As such, further investigation of the mandible may be warranted when this type of maxillary wall fracture is encountered to exclude concomitant injury.
讨论了一种迄今尚未报道的面部骨折类型。回顾了 22 例上颌后外侧壁骨折病例,其中 59%的病例同时伴有下颌骨骨折。这种损伤的提出机制是同侧下颌角突撞击上颌后外侧壁,伴下颌骨脱位或骨折。因此,当遇到这种类型的上颌外侧壁骨折时,应进一步检查下颌骨以排除合并损伤。
