本文复习了304例下颌骨陈旧性骨折病例，对各种类型骨折的诊治提出了自己的看法。强调在下颌骨粉碎性骨折的一期清创术中，不但要保留有软组织附丽的骨块，而且应尽量保留完全游离的骨块，以免造成术后下颌骨的骨质缺损、牙弓缩窄和严重的咬合紊乱。有骨缺损的陈旧性骨折，应尽量修复骨缺损，方能维持内固定的稳定性，加快骨愈合，获得良好、稳定的咬合关系。颌间牵引固定作为一种辅助手段，在错位愈合骨折的切开复位内固定中，有着重要作用。
This article reviewed 304 cases of mandibular old fractures, diagnosis and treatment of various types of fractures put forward their own views. Emphasize that in the first debridement of mandibular comminuted fracture, not only the soft tissue attached to the reebok should be retained, but also the complete free bone should be reserved as much as possible to avoid the postoperative bone loss of the mandible and the constriction of the arch And severe occlusion disorder. Old fractures with bone defects, should try to repair the bone defect, in order to maintain the stability of internal fixation, accelerate bone healing, access to good, stable occlusion relationship. Intermaxillary traction and fixation as an adjunct to the treatment of dislocation healing fractures open reduction and internal fixation, has an important role.
