下颌骨骨折的小型钛板坚固内固定技术

Miniplate osteosynthesis of mandibular fracture

目的 评估下颌骨骨折小型钛板坚固内固定的可靠性及其效果 ,探讨其优缺点。方法31例患者共 5 1处下颌骨骨折行小型钛板复位坚固内固定。复位技术及小型钛板的固定位置均参考Champy方法。结果 31例患者术后伤口均无感染 ,2例局部缝线裂开 ,其余均Ⅰ期愈合。 2 9例恢复到术前咬合关系 ,仅 2例出现局部咬合关系不良。术后张口度≥ 37mm者 2 8例。X线复查未见骨愈合不良或假关节形成。结论 下颌骨骨折的小型钛板坚固内固定效果可靠 ,避免了颌间结扎 ;对颞下颌关节功能影响小 ;口内手术入路避免了面部皮肤瘢痕 ;

Objective To evaluate the reliability and effectiveness of miniplate osteasynthesis in mandibular fractures. Methods 51 mandibular fractures in 31 cases treated with titanium miniplate osteosynthesis was analysed . Results No infection was found 28 cases had satisfied occlusion , 2 cases had unfavourable local malocclusion. The mouth opening of 28 cases were over 37 mm, only 2 cases under 37 mm 3 months postoperatively. Conclusions The miniplate osteosynthesis has the advantages over conventional intermaxillary fixation and wire fixation.
