Objective: To describe the clinical presentation, surgical management and postoperative outcomes of a patient with complex bilateral comminuted mandibular fractures, which resulted from high-velocity motorcycle trauma, and to highlight the role of preoperative planning using three-dimensional modeling in fracture management.
Methods:
Design: Case Report
Setting: Tertiary Academic Medical Center
Patient: One
Results: A 26-year-old man sustained severe mandibular trauma following a high-velocity motorcycle collision with a bus. Clinical evaluation, craniofacial computed tomography imaging, and intraoral examination revealed bilateral comminuted mandibular fractures involving the left body, angle, and ramus as well as the right symphysis, parasymphysis and body. Preoperative planning included review of computed tomography imaging and simulation using a three dimensional printed mandibular model to facilitate pre-bending of fixation plates. Surgical management consisted of maxillomandibular fixation followed by open reduction and internal fixation using titanium reconstruction plates and miniplates through combined submandibular and transoral approach. Successful reduction and fixation of the fracture segments were achieved with restoration of pre-injury occlusion and mandibular continuity. Postoperative recovery was uneventful, with no evidence of facial asymmetry, neurological deficits, or hardware complications. Follow-up examinations demonstrated satisfactory functional and cosmetic outcomes with progressive improvement in occlusion and mandibular mobility
Conclusion: Complex bilateral mandibular fractures resulting from high-energy trauma require careful preoperative evaluation and stable surgical fixation to restore mandibular anatomy and function. The use of three-dimensional printed models may serve as a valuable adjunct in surgical planning and plate adaptation in complex mandibular fracture management.
