Summary

Marginal mandibulectomy (MM) is an effective surgical technique for mandibular tumors. Careful preservation of periosteum and facial arteries minimizes immediate complications, though osteoradionecrosis (ORN) remains a concern.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Surgical Oncology

Background:

  • Marginal mandibulectomy (MM) is a recognized oncologically sound technique for mandibular tumors.
  • It aims to preserve function and cosmesis while achieving tumor control.

Purpose of the Study:

  • To review the experience with MM.
  • To analyze oncologic and nononcologic complications associated with MM.

Main Methods:

  • Retrospective review of 25 patients undergoing MM for tumors without cortical erosion.
  • Data collected included tumor characteristics, surgical details, and postoperative complications like osteoradionecrosis (ORN) and fractures.

Main Results:

  • A 92% local control rate was achieved in 25 patients.
  • Postoperative radiation therapy increased the risk of ORN (36.4%), leading to fractures in 2 patients.

Related Experiment Videos

  • Immediate postoperative fractures occurred in 2 patients due to technical factors.

    • Conclusions:

    • MM is an oncologically sound approach for tumors abutting the mandible.
    • Preserving periosteum and facial arteries is crucial to prevent immediate complications.
    • Osteoradionecrosis (ORN) is a significant long-term complication to consider.
