Abstract

Introduction: in high energy traumas caused by firearm projectiles may occur comminutive mandibular fractures. When it is not identified or inappropriately treated, these injuries can compromisse the individual’s health, with serious aesthetics and funcional complications. Objective: the aim of this study is report a case of surgical treatment of sequelae from firearm injury with comminutive fracture in the region of mandibular symphysis. Case report: patient sought the service of Oral and Maxillofacial Surgery and Traumatology after 1 month of unsatisfactory surgical treatment of a mandibular fracture caused by firearm projectile. Clinical examination revealed mobility to manipulation and bone exposure with purulent drainage. Computed tomography of the face shows bad fracture consolidation in the anterior region of the mandible with bone gap and discontinuity in the mandibular base and inadequate and poorly positioned osteosynthesis material. It was then proposed a new surgical approach with instalation of the reconstruction plate of 2.4mm locking system. In postoperative follow-up, the patient evolved with a functional and satisfactory mouth opening, with no mobility in bone fragments, restored mandibular framework and adequate positioning  of the fixation material. Final considerations: the cases of comminutive bone fractures show particular features that should be considered in their handling. In these cases, the choice of the fixation material is critical to therapeutic success and the use of prototyping sum for a satisfactory conduction of the case, ensuring shorter surgical time and better adaptation of the plate.
