title: The influence of mandibular advancement via modified sagittal split ramus osteotomy on the masticatory musculature.
abstract: 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.
