Area of Science:

  • Plastic and Reconstructive Surgery
  • Oral and Maxillofacial Surgery
  • Biomedical Engineering

Background:

  • Mandibular reconstruction presents significant challenges due to congenital anomalies, trauma, neoplasms, and osteoradionecrosis.
  • Conventional methods like bone grafting or metallic implants often fail due to poor vascularity, soft tissue deficits, or irradiated fields.
  • Free vascularized osteocutaneous flaps offer a superior alternative for complex mandibular defects.

Observation:

  • This report details experience with 8 cases utilizing iliac and scapular osteocutaneous free flaps for mandibular reconstruction.
  • Free vascularized bone grafts provide robust vascularized bone segments.
  • These flaps incorporate adequate skin lining for oral mucosa and external coverage, enabling "sandwich reconstruction".

Findings:

Related Experiment Videos

  • Free vascularized osteocutaneous flaps successfully addressed major mandibular defects.
  • The technique provides a desirable length of vascularized bone with integrated soft tissue.
  • Iliac crest free flaps demonstrated particularly reliable and satisfactory results.

Implications:

  • Vascularized bone grafting is a highly effective strategy for challenging mandibular reconstructions.
  • This approach significantly improves functional and aesthetic restoration in patients with large mandibular defects.
  • The iliac crest flap is a recommended option for achieving consistent, positive outcomes in major mandibular reconstruction.
