Abstract

Abstract: PURPOSE: This study aimed at proposing a new treatment-oriented classification and treatment algorithm of comminuted mandibular fractures based on analysis of 75 consecutive cases. METHODS: Seventy-five patients with comminuted mandibular fractures were retrospectively reviewed in this study. The classification was based on whether a stable occlusal relationship could be regained, morphology of mandible after trauma, degree of comminution and whether segmental mandibular bone defect happened. Based on traumatic condition, five classes were categorized and conservative treatment, miniplates fixation, reconstruction plates fixation, staged operations fixation with titanium meshes and bone flap transplantation were used for the management of the fracture. Forty-four patients in the experimental group were treated according to the classification while other thirty-one in the control group were not. RESULTS: After surgery, three patients developed infection, one patient presented malocclusion in the experimental group. Four patients developed infection, two patients had bone un-union, two patients presented malocclusion and one patient had mandibular asymmetry in the control group. CONCLUSIONS: The treatment-oriented classification and algorithm for comminuted mandibular fractures provide guidance for the choice of treatment methods and can decrease complication rate but further clinical research is needed.
