The New Method for the Mandibular Body Ostectomy

For the correction of mandibular deformities, we use frequently sagittal splitting ramus osteotomy. However, in patients who have good occlussion in the molar region, mandibular body ostectomy should be considered for such cases.To overcome some of disadvantages that mandibular body ostectomy has less bony contact between proximal and distal segments, and difficulty adjusting each segment, we improved this method by preserving lingual cortex via an intraoral approach.After separation of the buccal cortex with a fine osteotome, the lingual cortical bone is preserved by only distal or mesial single vertical osteotomy with a reciprocating saw. This osteotomy at the lingual cortex is carefully done following model surgery and cephalometric prediction.This technique could be used in cases in which good occlusion cannot be obtained by sagittal splitting ramus osteotomy.
