Abstract
Purpose
To ascertain the complications arising from open reduction and internal fixation of mandibular fractures and to elucidate if different osteosynthesis plating systems vary in treatment outcome.
Materials and Methods
This is a retrospective study. Parameters such as patient data, injury details, osteosynthesis implant system information, stability of fracture fragments, occlusion and complications were evaluated at different time intervals and logistic regression applied to determine the association of these factors with complications.
Results
Five hundred and ninety-three patients with mandibular fractures were included in this study (male 87.9% and female 12.1%), age range of 13–72 years (median = 22 years). Most fractures were caused by motor vehicle accidents (85.8%), assault (6.2%) and falls (4.7%). Parasymphyseal fractures were the most common (50.1%), followed by angle (35.2%) and body of mandible (25%). Median time interval between injury and intervention was 7 days (IQR 4–10). Median duration of follow-up from date of surgery was 72 days (IQR 30–230). 76.9% (456) were completely free of complications. Most complications (46%) occurred in the intermediate post-surgical period (1–6 weeks). Median interval period between surgery and complication was 15 days (IQR 7–67.5). Nerve injury and surgical site infection were the most common complications at 6.7% and 5.7%, respectively. There was a significant difference between the plating system in terms of complication outcome (p = 0.017).
Conclusion
Whilst the miniplate dimensions may be similar across different manufacturers, the complication outcome may differ between systems.
