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.
Methods: A retrospective review of 473 medical records of patients with MFF treated from June 2013 to December 2015 was conducted. Information on demographic characteristics of patients, aetiology of injury, types of MFF, and treatment was obtained. Descriptive analysis, Pearson's chi-squared test, and multiple logistic regression analysis were conducted. The level of significance was set at 0.05.
Results: Most patients treated for MFF were males (82.2%), aged 30 and below (63.1%), and from Malay ethnic (97.4%). Road traffic accident was the most common cause of MFF (83.1%), with motorcycle accident accounting for most injuries (73.6%). Orbital wall fracture was the most frequent MFF type (51.2%). About half of MFF patients (51.4%) were treated conservatively. Patients aged more than 20 years old were at higher odds of sustaining orbital wall fracture (AOR= 1.76; 95% CI: 1.214-2.558; P= 0.003) but were at lower odds of sustaining mandibular fracture (AOR= 0.47; 95% CI: 0.315-0.695; P= 0.001) than patients who are 20 years old and younger. Helmet use among motorcyclists was significantly associated with the nasal, orbital wall, and maxillary sinus wall fractures (P= 0.006, 0.010, and 0.004, respectively).
Conclusion: Motorcycle accident was the most common cause of MFF in Kelantan, Malaysia. Ages of patient and helmet use were associated with the type of MFF sustained. This study provides important information to facilitate the planning of MFF prevention strategies among motorcyclists and emphasizes the importance of using a helmet when riding a motorcycle.
