title: [Sagittal osteotomy of the ascending ramus. Technic and value of transcutaneous basilar osteotomy].
abstract: Dalpont II sagittal osteotomy is the procedure of choice for prognathism. The surface for bone consolidation can be significantly increased by an anterior extension of the section, favored in cases with major skeletal imbalance. Neurosensorial or bone complications often compromise sagittal surgery. Section may be difficult if the basilary bone is particularly solid; simple section is not entirely satisfactory due to the risk and is not well adapted to Dalpont II osteotomy. We present a novel technique for transcutaneous basilar osteotomy using a modified transjugal retractor and a mini saw blade. This technique gives a Dalpont II sagittal osteotomy with a long reproducible and safe valve.
