The modification of the sagittal split ramus osteotomy have been introduced to optimize vascularity to the proximal segment and minimize the influence of the masticatory musculature on relapse following the surgical-orthodontic correction of mandibular deficiency. The biologic basis for increased vascularity in comparison to conventional techniques has been proved. This study was done to evaluate the influence of the modified sagittal split ramus osteotomy on the masticatory musculature following surgical advancement of the mandible. The kinesiometric and electromyographic findings in five adults who underwent surgical advancement of the mandible reveal that surgical advancement of the mandible via modified sagittal split ramus osteotomy does not significantly influence muscles of mastication.
矢状劈开下颌升支截骨术的改良方法已被引入，以优化近端骨段的血供，并在正畸外科矫正下颌骨发育不全后，将咀嚼肌对复发的影响降至最低。与传统技术相比，血供增加的生物学基础已得到证实。本研究旨在评估改良矢状劈开下颌升支截骨术对下颌骨手术前徙后咀嚼肌的影响。对5例接受下颌骨手术前徙的成年人进行的运动测量和肌电图检查结果显示，通过改良矢状劈开下颌升支截骨术进行下颌骨手术前徙，对咀嚼肌没有显著影响。
