Introduction: The mandibular region presents a high rate of involvement in facial trauma, generating functional and aesthetic damages. Objectives: The aim of this study is to outline the profile of patients with mandibular fractures treated at the Conjunto Hospitalar do Mandaqui, focusing on its etiology, age/sex ratio and anatomic region affected. Method: An epidemiological survey of patients diagnosed with mandibular fractures attended at the Conjunto Hospitalar do Mandaqui from January 2011 to January 2019 through the analysis of medical records and imaging tests. Results: From the 434 patients with maxillofacial trauma treated during the study period, 353 (81%) presented man- dibular fracture with characteristics for inclusion in the study. The age group ranged from 2 to 78 years, male/female ratio was approximately 8:2. The main etiologies were traffic accidents (36.64%), aggressions (33.99%) and falls (15.58%). The most affected anatomic regions were the mandibular angle (26.72%), the mandibular body (24.22%) and the mandibular head (17.12%), and the coronoid process region was the least affected (0.42%). Conclusion: The prevalence and causes of mandibular fractures reflect the pattern of facial trauma of a population, and may help in the development of preventive measures, mainly to improve public policies for traffic safety and crime control.
