下颌骨骨折小型接骨板坚固内固定治疗体会

Clinical application of internal rigid fixation to mandibular fractures with miniplates

目的:总结应用小型接骨板坚固内固定治疗下颌骨骨折的临床经验。方法:对65例下颌骨骨折患者的临床资料进行回顾总结,所有患者应用小型接骨板行坚固内固定治疗。其中7例颏部正中骨折,12例下颌角骨折,16例颏孔区骨折,9例体部多发性骨折,5例体部粉碎性骨折;18例合并其他部位骨折。所有患者术前经临床检查和影像学检查明确骨折的位置和骨折线的数目后,分段夹板结扎、颌间弹性牵引,使移位的骨折段逐渐复位;术中经口内切开复位、细钢丝颌间结扎、小型接骨板坚固内固定;术后行临床检查和影像学复查,必要时颌间弹性牵引7～10d。结果:所有患者手术切口Ⅰ期愈合,治疗效果满意;临床检查所有患者关系良好、面部对称;影像学复查证实骨折线对位良好。结论:经口内切开小型接骨板坚固内固定辅以颌间固定治疗下颌骨骨折效果可靠,术后并发症少,是一种理想的手术方法。

Objective：The purpose of this study was to summarize our experience of the application of internal rigid fixation with miniplate for the treatment of mandibular fractures.Method： A retrospective analyisis of clinical data of 67 cases,who had experienced the anatomic reduction and rigid fixation by using miniplate.With the help of maxillomandibular distraction preoperation and postoperation and temporary maxillomandibular fixation during operation,the fracture bones were smoothly reduced and fixed.Results： Clinical and radiographic examination showed that all cases gained good clinical results and precise anatomic alignment of fracture postoperatively without infection,malocclusion,bone malunion or other complications.Conclusion： Mocortical miniplate fixation of the mandible is a reliable and effective techinique providing rigid fixation and an ideal modality for the treatment of mandibular fractures,combined with maxillomandibular fixation.
