Mandibular Fracture Due to Gunshot Injury with Reconstruction Using Osteosynthesis: case Report

Introduction: mandibular fractures caused by firearms are complex injuries that require specialized surgical management. Objective: to describe the surgical treatment of a multifragmentary mandibular fracture caused by a gunshot wound, using osteosynthesis techniques. Case Report: we present the case of a 29-year-old male patient who sustained a fracture in the body and left mandibular angle after a gunshot injury. The treatment consisted of an initial surgical debridement to prevent infections, followed by the placement of Erich arch bars for maxillomandibular stabilization. A second surgical procedure was performed for reconstruction through open reduction and internal fixation (ORIF), using 2.4 mm osteosynthesis plates with bicortical screws, via a Risdon-type extraoral approach. This approach allowed excellent exposure of the bone fragments, ensuring proper alignment while preserving the marginal branch of the facial nerve. The patient had an uneventful postoperative recovery, achieving adequate mandibular function. Conclusion: this case highlights the importance of timely and precise intervention to ensure complete functional recovery.
