SSRO is well known and very commonly used surgical technique worldwide for repositioning mandibular dental arch in both directions by advancement and setback movement of mandibular body [40]. SSRO provide a broad medullary contact between the bony segments that ensures stable healing capability. Internal fixation of bony segments eliminates or reduces the duration of intermaxillary fixation (IMF), plus a predictable immediate postoperative occlusion is achievable. The risk of neurovascular bundle injury is higher compared to intraoral vertical ramus osteotomy (IVRO) [41], and the risk of unfavorable fracture during the split between the bony segments was reported at 0.9% [42]. The risk of
