Abstract

Bilateral Sagittal Split Osteotomy (BSSO) is performed in orthognathic surgery to treat cases of dento-skeletal malformation. We present a shorter BSSO variant that allows for the realization of all orthognathic movements. This line respects the basilar rim and allows to modify the position of the mandibular angles. The splitting is more natural, separating the mandible into two anatomical subunits: the rising branch and the horizontal branch. This variant layout may also be associated with Chin Wing genioplasty.
