Classical orthognathic procedures have long been known to improve the facial esthetic contours and proportions of face by restoring the skeletal foundation, on which the soft-tissue drapes. Distraction osteogenesis was introduced to solve complex skeletal abnormalities in patients with craniofacial conditions that could not be solved by classical orthognathic surgery techniques. The gradual expansion in this group of patients showed not only greater skeletal stability, but the expansion at various tissue planes improved the facial appearance. In this report we review our experience in 22 cases with dentofacial skeletal abnormities for whom we believe achieved aesthetic outcomes could not habe been with classical orthognathic techniques alone. In addition, distraction at the interdental regions allowed for "tailoring" of the osteotomies and for simultaneous expansion at the occlusal level.
经典的正颌手术通过恢复骨骼基础来改善面部的美学轮廓和比例,软组织则悬挂在骨骼基础上。牵张成骨术的引入是为了解决颅面畸形患者中无法通过经典正颌手术技术解决的复杂骨骼畸形问题。在这群患者中,逐渐扩大的治疗范围不仅显示出更大的骨骼稳定性,而且各个组织层面的扩张也改善了面部外观。在本报告中,我们回顾了我们在 22 例牙颌面骨骼畸形患者中的经验,我们认为仅通过经典的正颌技术无法达到美学效果。此外,牙间区域的牵张允许“定制”截骨术,并同时在咬合平面上进行扩张。
