全面部骨折手术治疗的临床研究

目的 探讨全面部骨折及并发症的诊治要点，摸索适合于口腔颌面部骨折治疗的生物学固定原则。方法 采用X线头影测量分析、模型外科、骨切开复位等技术，结合生物学固定的原则矫治48例全面部骨折所致牙颌面畸形和咬袷紊乱。结果 本组患者均获得满意的功能和形态效果。结论 全面部骨折必须通过术前精确的设计，有组织、有步骤地达到功能与形态并举的治疗效果。同时，骨折治疗必须重视骨的生物学特性，如选择恰当的接骨板和螺钉系统以及正确的复位固定方法，坚强固定和弹性固定相结合，复位固定要修复骨缺损。

Clinical study of surgical treatment for panfacial fractures

Objective To discuss the surgical treatment points for panfacial fractures and complications and explore the biological osteosynthesis principles suitable for treatment of oral and maxillofacial fractures. Methods According to biological osteosynthesis principles, 48 cases with facial deformity and occlusion disturbance resulted from panfacial fractures were treated by using such techniques ineluding X-ray cephalometric analysis, model surgery, open reduction and rigid internal fixation. Results All cases obtained successful correction of the maxillofacial deformities. Conclusions Accurate preoperative plan, systematical and appropriate choice of surgical methods are key to good treatment outcome. At the same time, treatment of bone fractures must attach importance to biological characteristics of bone, for example, appropriate choice of plates and screw system, appropriate choice of reposition and fixation methods, the combination of rigid fixation and elasticity fixation, and reconstruction of bone defects.
