Summary

Supplemental maxillomandibular fixation did not improve outcomes for mandibular fractures treated with monocortical miniplates. This study found no significant difference in complication rates between groups with and without this additional fixation.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Trauma Surgery
  • Biomaterials Engineering

Background:

  • Monocortical miniplate fixation is a standard technique for mandibular fractures.
  • Clinical effectiveness of monocortical miniplate fixation alone is debated.
  • Supplemental fixation methods are sometimes employed to enhance stability.

Purpose of the Study:

  • To evaluate the clinical necessity and impact of supplemental maxillomandibular fixation in conjunction with monocortical miniplate osteosynthesis for mandibular fractures.
  • To compare complication rates and treatment outcomes between patients receiving supplemental fixation and those treated with miniplates alone.

Main Methods:

  • Retrospective analysis of 287 patients with 499 mandible fractures over a 5-year period.
  • Matched pairing of 65 patients with identical fractures and plating schemes.

  • Group 1: Monocortical plating with supplemental maxillomandibular fixation. Group 2: Monocortical plating without supplemental fixation.

    • Main Results:

    • Major complication rates were 11% (with supplemental fixation) and 9% (without), with no statistical significance (p > 0.05).
    • Total complication rates were 17% (with) and 20% (without), also not statistically significant (p > 0.05).
    • No demonstrable outcome advantage was found for using supplemental maxillomandibular fixation.

    Conclusions:

    • Supplemental maxillomandibular fixation does not appear to offer a statistically significant advantage in reducing complications for mandibular fractures treated with monocortical miniplate osteosynthesis.
    • Clinical decision-making regarding supplemental fixation should consider the lack of evidence for improved outcomes in this patient cohort.
