Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Navigation Technology
  • Medical Imaging

Background:

  • Orthognathic surgery presents challenges due to limited surgical field visibility.
  • This limitation increases the risk of perioperative complications.
  • Computer-aided navigation was investigated to address these challenges.

Purpose of the Study:

  • To evaluate the utility of computer-aided navigation in orthognathic surgery.
  • To assess the safety and efficacy of navigation-guided procedures.

Main Methods:

  • A cohort of 10 patients with facial deformities underwent orthognathic surgery.
  • Procedures included Le Fort I osteotomy, sagittal split ramus osteotomy, and reduction malarplasty.
  • All surgeries were performed using a computer-assisted navigation system.

Main Results:

  • Computer-assisted navigation enabled successful treatment for all 10 patients.
  • The navigation system provided real-time visualization of instruments on a monitor.
  • All surgical maneuvers were executed safely.

Conclusions:

  • Orthognathic surgery, including Le Fort I osteotomy and sagittal split ramus osteotomy, can be safely performed with surgical navigation.
  • Navigation systems facilitate accurate execution of preoperative plans.
  • Real-time instrument visualization prevents injury to critical anatomical structures.
