Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Surgical Navigation Technology

Background:

  • Mandibular osteotomies are crucial for treating craniomaxillofacial disorders, but continuity loss causes esthetic and functional deficits.
  • Computer-assisted surgery, rapid prototyping, and surgical navigation have advanced mandibular resection and reconstruction over 30 years.
  • Existing navigation methods for mandibular surgery often lack the ability to maintain full jaw motility during procedures.

Purpose of the Study:

  • To describe a novel method for navigating the jaw with full motility during surgical resection and reconstruction.
  • To present a technique that avoids the need for intermaxillary fixation during mandibular procedures.
  • To evaluate the accuracy and feasibility of this new dynamic jaw navigation approach.

Main Methods:

  • Developed a surgical navigation method positioning the dynamic reference frame directly on the mandibular branch.
  • Applied the technique during mandibular surgical resection and reconstruction procedures.
  • Utilized real-time feedback from surgical navigation to guide the procedure without intermaxillary fixation.

Main Results:

  • Successfully navigated the jaw with full motility throughout the surgical procedures.
  • Achieved accurate surgical navigation without requiring intermaxillary fixation.
  • Demonstrated the feasibility and precision of the described method in a series of cases.

Conclusions:

  • The novel method allows accurate surgical navigation of the jaw, maintaining full mobility and eliminating the need for intermaxillary fixation.
  • This technique can significantly facilitate jaw resection and reconstructive surgery, enhancing precision and accuracy.
  • Further investigation is warranted to refine the method and define its clinical indications for craniomaxillofacial surgery.
