title: A quantitative histologic study of tissue responses to ramal sagittal splitting procedures.
abstract: The viability of bone after sagittal splitting of the mandibular ramus by two techniques was studied. Decalcified sections of bone were studied with light microscopy; ground sections of bone labeled with tetracycline were studied with ultraviolet microscopy. The data indicate that avascular necrosis of the proximal fragment occurs after conventional Obwegeser-Dal Pont sagittal split osteotomy. Viability of the fragment was maintained by using a musculoperiosteal pedicle on the proximal fragment.
