  • Title: Real-time navigation-assisted orthognathic surgery.
    Author: Shim BK, Shin HS, Nam SM, Kim YB.
    Journal: J Craniofac Surg; 2013 Jan; 24(1):221-5. PubMed ID: 23348289.
    Abstract:
    BACKGROUND: One limitation of orthognathic surgery is the narrow surgical field, which makes it difficult to view the operative site directly. Thus, many perioperative complications can occur. In this study, we evaluated the usefulness of computer-aided navigation techniques in orthognathic surgery. METHODS: We enrolled 10 patients (3 men and 7 women) with facial deformities who were treated between July 2010 and February 2011. A Le Fort I osteotomy, sagittal split ramus osteotomy, and reduction malarplasty were performed with guided navigation. RESULTS: All 10 patients were treated successfully using the computer-assisted navigation surgery. Using the navigation system, instruments were visualized on a monitor in real time and all maneuvers were performed safely. CONCLUSIONS: Orthognathic surgery, such as a Le Fort 1 osteotomy, sagittal split ramus osteotomy, and reduction malarplasty, can be performed safely under the guidance of a surgical navigation system. Navigation systems enable surgeons to carry out preoperative plans accurately without injuring important anatomic structures because the positions of the instruments can be visualized on site in real time.
