Outcome parameters evaluated were: (1) clinical epidermiology of patients undergoing orthognathic surgery, (2) evaluate the surgical accuracy of maxillary and mandibular repositioning by comparing the dento-skeletal changes (SNA, SNB, SN-GoGn, vertical and horizontal measurements in upper incisal edge) between the cephalometric prediction tracing and the one week postsurgical cephalometric tracing, (3) evaluate patient satisfaction regarding aesthetics and function and (4) determine the incidence of postoperative complications.
