Introduction: Injuries caused by firearms involving the face are a real challenge for surgeons concerning treatment of these patients, due to its complexity, associated with energy dissipated by the projectile, degree of bone comminution, tissue loss, among other factors. Objective: This study aims to report a clinical case of a patient with mandibular defect caused by firearm, treated using reconstruction plate. Results and Discussion: Combination between projectile structure, kinetic energy and interaction with tissues will define the aspects of maxillofacial trauma. As far as we concern, lesions with great bone comminution treated with early open fixation may cause loss of nutrition and vascularization of the affected bone tissue, with subsequent infection and tissue necrosis. The patient is in postoperative follow-up of six months, reestablishing the mandibular anatomy, occlusion, and without pain and functional complaints. Conclusion: Thus, traumas by firearms are a real challenge for surgeons, due to its complexity and patient expectation to restore esthetics and maxillofacial function. A proper ballistic evaluation of the trauma, and characteristics of the lesion associated to clinical and imaging examinations become essential for the success of treatment.
