The big goal unsettled in treatment of the skeletal deformities is the planning precision. This fact is especially important in
asymmetrical deformities. The aim in this article is to present a method that allows a three-dimensional evaluation of facial
complex. Also, this method permits to simulate osteotomies and skeletal movements. Finally, the STO information transmission to
a CAD/CAM system allows the surgical splint construction.
