In syndromic craniosynostosis, the relation between the supraorbital area and the frontal bone is not good, and it is not possible to reform this area with 1-block advancement. To avoid this problem, the frontal bone is separated from the fronto-orbital bandeau, each is reshaped and remodeled separately, and then both are reattached. The retrusion of the midface, especially in syndromic craniosynostosis, is usually greater than that of cranial bones, so the technique usually separating the midface from the cranium is Le Fort III osteotomy, which allows differential distraction of each part. In this procedure, the cranial and midfacial bones are advanced simultaneously and differentially, both to the planned extent, in a single-stage operation, using rigid external distractor II, correcting exorbitism, respiratory embarrassment, and cranial structures and avoiding eye complications in the future. This procedure was used, with a follow-up, in 10 patients with syndromic craniosynostosis from 2 to 5 years.
在综合征性颅缝早闭中，眶上区域与额骨之间的关系不佳，无法通过整块推进来重塑该区域。为避免此问题，将额骨与额眶带分离，分别对二者进行重塑和改建，然后重新连接。面中部后缩，尤其是在综合征性颅缝早闭中，通常比颅骨后缩更严重，因此通常将面中部与颅骨分离的技术是Le Fort III截骨术，该术式可对各部分进行差异化牵引。在此手术中，使用刚性外部牵引器II，在一期手术中将颅骨和面中部骨骼同时并差异化地推进至计划范围，矫正眼球突出、呼吸窘迫以及颅骨结构问题，并避免未来出现眼部并发症。该手术方法应用于10例综合征性颅缝早闭患者，随访时间为2至5年。
