Area of Science:

  • Oral and Maxillofacial Surgery
  • Biomedical Engineering
  • Reconstructive Surgery

Background:

  • Mandibular reconstruction is crucial for traumatic or postsurgical defects.
  • Autologous osteocutaneous fibula free flaps are used for large mandibular defects.
  • Current pre-operative planning software has limitations in recreating native mandibular contour.

Purpose of the Study:

  • To present a novel pre-operative planning system for mandibular reconstruction.
  • To optimize bony osteotomies and bone segment orientation.
  • To improve the reliability of osteocutaneous fibula free flaps by prioritizing cutaneous perforators.

Main Methods:

  • Development of a novel pre-operative planning system.
  • System focuses on optimizing the number and location of bony osteotomies.
  • Prioritizes the position and number of cutaneous perforators to the fibula flap.

Main Results:

  • The system aids in optimizing surgical planning for mandibular reconstruction.
  • Enhances the orientation of harvested bone segments.
  • Improves the reliability of osteocutaneous fibula free flaps.

Conclusions:

  • The novel pre-operative planning system offers an improvement over existing methods.
  • It enhances the precision of mandibular reconstruction using fibula free flaps.
  • Prioritizing perforator location improves flap viability and surgical outcomes.
