Sagittal genioplasty: a new technique of genioplasty.
A new technique for performing genioplasties is described. Antero-posterior and vertical deformities of the chin can be corrected and because a large surface area of bone remains in contact under compression following the osteotomy, a stable osteosynthesis is achieved. Access for fixation, using either wires or leg screws, is good and this feature, combined with the mechanical advantage obtained from the osteotomy cuts, contributes to great stability. The technique is safe, since there is minimal periosteal stripping; the bone cuts avoid the mental nerves and the mobilised bony chin retains a vascularised muscle pedicle.
