Summary

The Champy technique using a single miniplate is now the preferred method for treating mandibular angle fractures. Intraoperative maxillomandibular fixation (MMF) is no longer considered mandatory in all cases.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Trauma Surgery
  • Orthognathic Surgery

Background:

  • Mandibular angle fractures present management challenges and high complication rates.
  • Optimal treatment strategies for these fractures remain a subject of debate.
  • Historically, rigid internal fixation with maxillomandibular fixation (MMF) was standard; however, miniplates and evolving fixation techniques are now prevalent.

Purpose of the Study:

  • To examine current trends in the management of simple, noncomminuted mandibular angle fractures.
  • To assess the evolving role of intraoperative MMF in conjunction with internal fixation techniques.

Main Methods:

  • A survey was distributed to North American and European AO ASIF faculty in July 2001.
  • Statistical analysis, including Fisher's exact and chi-square tests, was employed to evaluate the survey responses.

  • Results were considered statistically significant if P < .05.

    • Main Results:

    • The Champy technique (single miniplate on the superior border) is the preferred method for 51% of surgeons treating over 10 mandibular fractures annually.
    • While 13% primarily use tension band and bicortical screw plates, 73% utilize this in certain situations.
    • Intraoperative MMF is not considered mandatory by 41% of surgeons for simple, noncomminuted angle fractures.

    Conclusions:

    • The management of mandibular angle fractures is evolving, with a shift towards less rigid fixation methods.
    • The single miniplate (Champy technique) has emerged as the favored approach among AO faculty.
    • The necessity of intraoperative MMF is being re-evaluated, with a growing number of surgeons opting against it in specific scenarios.
