Craniofacial osteotomies have by convention been bilamellar translocations of the entire substance of the dysmorphic bone. This approach limits the surgeon by reducing the stable bone mass available for fixation, creating dependence on concave surfaces. Most important, it changes the bony topography that determines the preoperative plan. This paper presents a new craniofacial concept and technique used in 26 patients with various dysmorphic syndromes who were reconstructed by performing a lamellar split osteotomy. This technique maintains the internal lamella in its native position, thereby allowing it to act as a reference for the bony topography and providing a stable facial framework for rigid fixation. This interlamellar osteotomy has led to improved aesthetic results in the orthomorphic reconstructions of congenital and other deformities. It can be used in any aesthetic patient in whom contour changes or augmentation of form is desired. It is recommended as a preferred method for achieving quantitative contour improvement in patients over 3 years of age.
按照惯例，颅面截骨术是对畸形骨的整个骨质进行双层移位。这种方法限制了外科医生，因为它减少了可用于固定的稳定骨量，导致对外凹面的依赖。最重要的是，它改变了决定术前计划的骨地形。本文介绍了一种新的颅面概念和技术，应用于26例患有各种畸形综合征的患者，这些患者通过进行分层劈开截骨术进行重建。该技术将内层骨片保持在其原始位置，从而使其能够作为骨地形的参考，并为坚固固定提供稳定的面部框架。这种层间截骨术在先天性及其他畸形的正颌重建中带来了更好的美学效果。它可用于任何希望改变轮廓或增加外形的美容患者。对于3岁以上希望实现定量轮廓改善的患者，建议将其作为首选方法。
