Abstract
Background: Mandibular fractures usually involve one or multiple sites with different patterns which depend on various factors such as the force applied, type of injury, in addition to the morphological and anatomical characteristics of the mandible. Few studies proved a relationship between mandibular angle measurement and fractures in the angle region. In this study, we looked through the ties of gonial angle measurement and all associated ipsilateral mandibular fractures. Objective: To investigate weather gonial angle measurement would be one predictor to the location of mandibular fractures. Method: This retrospective cohort study included patients diagnosed with mandibular fractures between 2018 and 2023. 100 cases were randomly selected. The gonial angle was measured using 3D C.T. scans. Fracture patterns were categorized into two groups: Group A (Angle region) and Group B (Not Angle region). Results: The mean gonial angle in patients with fractures in the angle region was 125 degrees, compared to 117 degree in patients with fractures in the non-angle region, which was a statistically significant difference (p < 0.001). Conclusion: The mandibular gonial angle is a powerful determinant factor affecting the mandibular fracture pattern. The stronger and less obtuse mandibular angle the more likely a fracture pattern to spare the angle region.
