摘要
目的 总结分析下颌骨前突畸形患者应用微动力手术系统行下颌骨升支矢状劈开截骨手术的治疗特点。方法 术前正畸治疗、X线头影测量分析、模型外科、制作咬板 ;手术选用下颌升支矢状劈开截骨术 ,术后颌间固定 1～ 2周。结果 下颌骨升支矢状劈开截骨术治疗下颌骨前突畸形 ,其关系恢复正常 ,面容改善 ,效果满意。结论 下颌骨升支矢状劈开截骨术可有效地矫正下颌骨前突畸形 。
Objective To analyze the surgical management applied to the patients with mandibular prognathism. The management was sagittal split ramus osteotomy (SSRO) using micro machine surgical apparatus.Methods The preoperative routines such as presurgical orthodontic treatment, cephalometric analysis, model surgery and occlusion splint were performed as necessary. During the surgery, we applied SSRO to the patients with postsurgical intermaxillary fixation for 1 2 weeks. Results SSRO is an effective method of treating mandibular prognathism. The results show improvement in the occlusion and facial contours as well the restoration of function.Conclusion SSRO can successfully improve the symptoms of mandibular prognathism, including restoring the occlusion, facial contour and function.
