We present an unusual dislocation of the mandibular ramus after a low condylar fracture associated with a fracture of the opposite body of mandible. As closed reduction failed, both fracture sites were exposed. The mandibular ramus was dislocated behind the styloid process, which was not shown on the preoperative radiographs. The intermediate fragment was freed and the fractures treated by miniplate osteosynthesis. The patient made an uneventful recovery with no residual deformity.
我们报告一例罕见的下颌骨髁突低位骨折合并对侧下颌骨体部骨折后出现的下颌支脱位。由于闭合复位失败，两个骨折部位均予以暴露。下颌支脱位至茎突后方，术前X线片未显示此情况。游离中间骨折块，采用微型钢板内固定治疗骨折。患者恢复顺利，无残留畸形。
