Abstract
Orthognathic surgery is the surgical correction of skeletal anomalies or malformations involving the mandible or the maxilla. Therefore, an accurate objective prediction analysis of the final treatment outcome has become an important part of the consultation for any patient seeking orthognathic surgery. In the present study a case series of patients planned on tracing of cephalometric radiographs is reported in order to assess the effectiveness of planning and treatment and pertinent literature discussed. The study population was composed of 44 patients (28 females and 16 males, median age 28 years) affected by class II and III skeletal malocclusion or long face. Patients were evaluated by means of 4 teleradiograpies: one at the admission, one before surgery, one after surgery and one at the end the follow-up. Slavicek cephalometric analysis was performed. A logistic analysis was performed in order to dected those variables associated to the clinical outcome. Among the skeletal variables, the mandibular trend is the only variable that has an impact on clinical outcome. None of the teeth variables has statistical significance. Orthognathic surgery involving mobilization, repositioning, and fixation of the maxilla and mandible. The jaw is corrected to improve functional difficulties in the musculoskeletal system involving the mouth, including difficulties with mastication and pronunciation, and to treat facial appearance due to abnormal growth.

Our data demonstrated that patients planned on tracing of cephalometric radiographs have good clinical outcome.
