Abstract
OBJECTIVES
The objective of this study was to evaluate the efficiency of three methods of isolated mandibular fracture intraoperative reduction.
MATERIALS AND METHODS
This 6-year retrospective study included patients with isolated extra-articular mandibular fractures who would benefit from osteosynthesis. The endpoint was postoperative occlusion according to the type of intraoperative immobilization: screws, arch, or manual reduction.
RESULTS
A total of 145 patients were included, with 233 fractures. Forty-five patients underwent manual reduction without maxillo-mandibular fixation (MMF), 51 MMF with screws, and 49 MMF with arch, with 11.1%, 5.9% and 4.1% of patients in these groups experiencing postoperative malocclusion, respectively. The overall malocclusion rate was 6.9%. There was no significant difference among the 3 methods according to univariate statistical analysis (p = 0.42) or after comparing MMF (grouping screws and arches) to manual reduction without MMF (p = 0.29).
CONCLUSION
This study did not show a significant difference between the different methods of intraoperative reduction of isolated extra-articular mandibular fractures, even though intraoperative MMF was much more commonly used for complex fractures. However, there is a non-significant tendency to get a better post-operative occlusal result with MMF, which remains the reference traitement. Intraoperative manual reduction without MMF may be used within trained teams in some instances.
