The osteotomy of the maxilla using the Le Fort I technique, today routinely performed in the down-fracture-technique, has changed surgical corrections of dentofacial deformities fundamentally. It offers a three-dimensional correction of the maxilla and also of the whole facial skull. Furthermore the upper dental arch can be expanded, intruded and shortened using a sagittal or transversal osteotomy in addition to a complete transposition of the maxilla. Planning of a maxillary osteotomy is performed under consideration of the clinical situation, the casts and the lateral cephalogram. The mandible must be considered at an early stage of the preoperative planning, since the mandible will follow all transpositions of the maxilla by rotating with the TMJ. Only by performing a simultaneous osteotomy of the mandible, a broad spectrum of indications for maxillary osteotomy will result and practically every desired profile of the lower third of the face can be achieved using combined maxillary and mandibular osteotomies.
采用Le Fort I技术进行上颌骨截骨术，如今通常在下行骨折技术中进行，从根本上改变了牙颌面畸形的外科矫正方法。它能对上颌骨乃至整个面颅骨进行三维矫正。此外，除了上颌骨的完全移位外，还可通过矢状或横向截骨术对上颌牙弓进行扩弓、压低和缩短。上颌骨截骨术的规划需综合考虑临床情况、模型和头颅侧位片。在术前规划的早期阶段就必须考虑下颌骨，因为下颌骨会随着颞下颌关节的旋转而跟随上颌骨的所有移位。只有同时进行下颌骨截骨术，才能产生广泛的上颌骨截骨术适应证，并且通过上颌骨和下颌骨联合截骨术几乎可以实现面部下三分之一的任何理想外形。
