Frontofacial monobloc advancement is one of the most rewarding techniques for correcting aesthetic and functional problems of patients with severe craniofacial synostosis, which can advance the upper and middle third of the face simultaneously. Application of gradual distraction technique has been reported to reduce notorious risks after a frontofacial monobloc advancement. The so-called "bibloc advancement" is a derivative of the frontofacial monobloc advancement. "Facial bloc" is horizontally divided into 2 different components: fronto-orbital component and maxillozygomatic component. From a different angle, it can be described as a combination of fronto-orbital advancement and Le Fort III advancement. Two pairs of distracters (1 internal for the supraorbital area and 1 external for the maxillozygomatic area with a pair of cross-facial pinning) were applied after the so-called bibloc osteotomy. Advancement of the upper and middle third of the face was done individually. This technique can be a good option for treating infants with severe syndromic craniofacial synostosis.
额面部整块前移术是矫正重度颅面骨缝早闭患者美学和功能问题最有效的技术之一，该技术可同时前移面部的上三分之一和中三分之一。据报道，应用渐进性牵引技术可降低额面部整块前移术后的显著风险。所谓的“双块前移术”是额面部整块前移术的衍生术式。“面部块”在水平方向上分为2个不同部分：额眶部和上颌颧骨部。从不同角度看，它可描述为额眶前移术和勒福Ⅲ型截骨术的联合。在所谓的双块截骨术后应用两对牵引器（一对用于眶上区域的内置牵引器和一对用于上颌颧骨区域的外置牵引器，并伴有一对跨面部固定针）。面部的上三分之一和中三分之一分别进行前移。该技术对于治疗患有重度综合征性颅面骨缝早闭的婴儿可能是一个不错的选择。
