Surgical repositioning of the dento-skeletal components of the face, combined with appropriate orthodontic treatment, can be used to improve function and aesthetics. An extensive number of osteotomies are performed within the maxillofacial region. The most common of these are the Le Fort I osteotomy of the maxilla, the bilateral sagittal split osteotomy of the mandibular ramus, and the horizontal osteotomy of the anterior mandible. The attainment of three dimensional stability following corrective jaw surgery continues to be a major problem in the post-surgical period, in spite of the widespread adoption of rigid internal osteosynthesis. The evolution of these osteotomies to advance dento-skeletal components is traced from their inception to the present day and the concept of stability is explained (Part I). This serves as a prelude to an investigation into the stability of these procedures, undertaken in isolation or combination, to advance selected segments of the mid- and lower face (Parts 2, 3, 4, 5).
面部牙-骨骼结构的外科重新定位，结合适当的正畸治疗，可用于改善功能和美观。颌面区域会进行大量的截骨手术。其中最常见的是上颌骨的勒福Ⅰ型截骨术、下颌升支的双侧矢状劈开截骨术以及下颌前部的水平截骨术。尽管坚固内固定已被广泛采用，但正颌外科手术后三维稳定性的实现仍然是术后阶段的一个主要问题。本文追溯了这些用于推进牙-骨骼结构的截骨术从起源到当今的发展历程，并解释了稳定性的概念（第一部分）。这为后续对这些单独或联合进行的手术推进中面部和下面部特定节段的稳定性研究（第二、三、四、五部分）奠定了基础。
