介绍了一种新的骨牵引钩截骨牵张成骨（0130）和缝牵张成骨（SDO）技术。截骨牵张成骨技术适用于成年患者。缝合牵引成骨技术适用于6 - 12岁的年轻患者。牵引系统包括面弓、正畸弹力带和骨牵引钩。骨载牵引钩由钛制成，两个牵引钩横向或向下延伸。当需要进行Le Fort III截骨术时，将骨牵引钩通过鼻孔插入在外侧下梨状孔处钻的骨孔中。当不需要截骨时，仅放置骨载牵引钩。对于Le Fort III型截骨术成人患者，在截骨牵引成骨技术中使用重弹性材料，而对于年轻患者，使用轻力和轻弹性材料。3例成人患者和4例儿童患者分别采用截骨牵引和缝合牵引治疗。所有7名面中部发育不良的患者均建立了和谐的面部轮廓和正常的咬合关系。影像学检查显示面中部骨骼平衡前移。建议采用缝牵引成骨技术治疗儿童面中部发育不良，因为其简单且相对无创。因此，作者建议面中部发育不全应在较年轻时采用该技术进行治疗，从而可能消除在较大年龄时进行Le Fort III截骨术的需要。
A new technique of osteotomy distraction osteogenesis (0130) and sutural distraction osteogenesis (SDO) by the use of bone-borne traction hooks is presented. The technique of osteotomy plus distraction osteogenesis is suitable for adult patients. The technique of sutural distraction osteogenesis is suitable for young patients, ages 6 through 12 years. The distraction system consists of a face-bow, orthodontic elastics, and bone-borne traction hooks. The bone-borne traction hooks are made of titanium, with two traction hooks running laterally or downwardly. When a Le Fort III osteotomy is needed, bone-borne traction hooks are inserted through the nostrils into a bone hole drilled at the lateral-inferior pyriform aperture. When no osteotomy is needed, only the bone-borne traction hooks are placed. Heavy elastics were used in the technique of osteotomy distraction osteogenesis for Le Fort III osteotomy adult patients, whereas light forces and thus light elastics were used for younger patients. Three adult patients and four children were treated by osteotomy distraction and sutural distraction, respectively. All seven patients with midfacial hypoplasia established a harmonious facial profile and normal occlusal relationships. Radiographic examination showed balanced advancement of the midfacial skeleton. It is suggested that the treatment of midfacial hypoplasia in children by the technique of sutural distraction osteogenesis is to be preferred because of its simplicity and relative noninvasiveness. Thus, the authors suggest that midfacial hypoplasia should be treated at a younger age by this technique, potentially eliminating the need for a Le Fort III osteotomy at an older age.
