The use of rigid fixation with orthognathic surgery was greeted by both excitement and healthy concern when it began to find its way into the literature approximately 10 years ago. The purpose of this paper is to review the literature and make comments based on the experience of the senior author on whether one of the early premises was true. Has rigid fixation improved stability with orthognathic surgery? The authors chose to examine mandibular advancements treated with a bilateral sagittal split osteotomy and maxillary osteotomies treated with a Le Fort I osteotomy. When compared to wire osteosynthesis, rigid fixation has improved stability; however, the individual move associated with the osteotomy must be considered. In some cases, auxiliary techniques should be used to ensure stability. Condylar resorption with mandibular advancement continues to be an area of concern.
大约10年前，正颌外科手术中使用坚固内固定开始出现在文献中时，引发了人们的兴奋和合理关注。本文的目的是回顾相关文献，并根据资深作者的经验，对早期的一个前提是否正确发表评论。坚固内固定是否提高了正颌外科手术的稳定性？作者选择研究采用双侧矢状劈开截骨术治疗的下颌前徙术以及采用Le Fort I截骨术治疗的上颌截骨术。与钢丝骨固定术相比，坚固内固定提高了稳定性；然而，必须考虑与截骨术相关的个体移动。在某些情况下，应使用辅助技术来确保稳定性。下颌前徙术后髁突吸收仍然是一个令人关注的领域。
