摘　　要：目的:探讨上颌骨矢状骨折复位内固定的方法。方法:回顾分析了15例上颌骨矢状骨折的治疗,10例术前行模型外科分析制作导板,其中8例手术中应用LeFortΙ型截骨、折断降下技术,其余病例应用了离断翼上颌连接,松解骨折片的操作;所有病例均于上颌骨前部以微型钛合金接骨板内固定。结果:15例患者术中骨折复位良好;14例关系恢复,1例术后骨折片移位。结论:正颌外科技术是治疗上颌骨矢状骨折的有效方法;矢状骨折时,上颌骨前部仅应用1枚微型钛合金接骨板固定机械抗力可能不足。Objective：To evaluate the technique of reduction and rigid internal fixation of sagittal maxillary fracture. Methods：15 cases of sagittal maxillary fracture were reviewed. Occlusal guide plates were prepared preoperatively by model surgery analysis in 10 cases; Le Fort Ⅰ osteotomy and down-fracture were done in 8 cases; Pterygomaxillary junctions were also separated in the other cases. Internal fixation was applied along the anterior maxillary surface by using microplates in all 15 cases. Results：Anatomically reduction was achieved in all cases; Occlusion of 14 cases was corrected except one case of fracture re-displaced. Conclusion ： Orthoguathic technique is effective treatment of sagittal maxillary fracture; One microplate applied along anterior maxillary surface may be not enough to ensure the fixation of sagittal maxillary fracture.
