The purpose of this study was to investigate the characteristic multidetector CT (MDCT) findings, especially the prevalence of location, of mandibular fractures resulting from falls and violence. A prospective study was performed in 217 patients with mandibular fractures resulting from falls or violence underwent 64-MDCT. Mandibular fractures were classified into four types: median, paramedian, angle and condyle. Statistical analysis of the relationship between cause and mandibular fracture location was performed using χ2 test and logistic multivariate regression analysis. The results showed that the percentages of cases resulting from falls and violence were 55.8% and 44.2% of paramedian type (p=0.001), 46.4% and 53.6% of angle type (p=0.000) and 87.8% and 12.2% of condyle type (p=0.000), respectively. This study indicated a significant relationship between cause and condyle type (odds ratio (OR)=3.303, p=0.009), paramedian type (OR=0.339, p=0.017) and angle type (OR=0.313, p=0.019), respectively. In conclusion, the results of the presented study suggest the characteristic MDCT findings, especially the prevalence of location, of mandibular fractures resulting from falls and violence.
