A miniature system of distraction devices has been employed for maxillary-midface advancement in two children with cleft lip and palate, class III malocclusion, and associated midfacial hypoplasia. The devices are made with commercially available palatal expansion screws linked to rigid fixation plates. A midfacial osteotomy is used, and distraction is begun on the third postoperative day. In the first child, a 7-year-old boy, the midface was distracted 11 mm sagittally and 4 mm inferiorly. In the second patient, a 4 1/2-year-old girl with unilateral cleft lip and palate and midfacial retrusion, an 11-mm distraction was carried out in the vertical and sagittal direction. There were no complications, and none of the devices failed. Maxillary-midfacial distraction osteogenesis to correct severe maxillary-midfacial hypoplasia in children with clefts and other craniofacial disorders permits early intervention with potentially less invasive techniques than are currently available.
一种微型牵引装置系统已用于两名唇腭裂、III类错牙合畸形及相关面中部发育不全的儿童的上颌-面中部前移。这些装置由与刚性固定板相连的市售腭扩展螺钉制成。采用面中部截骨术，并在术后第三天开始牵引。在第一个儿童中，一名7岁男孩，面中部在矢状方向上被牵引11毫米，在下方被牵引4毫米。在第二个患者中，一名4岁半患有单侧唇腭裂和面中部后缩的女孩，在垂直和矢状方向上进行了11毫米的牵引。没有并发症，且没有一个装置出现故障。上颌-面中部牵引成骨术用于矫正患有腭裂和其他颅面疾病儿童的严重上颌-面中部发育不全，与目前可用的技术相比，它允许采用潜在侵入性较小的技术进行早期干预。
