The World Health Organization considers the victims of interpersonal violence to be a medical priority. In order to provide services at the highest level, we aimed to evaluate the patterns of maxillofacial fractures caused by interpersonal violence, in order to treat, counsel and guide these patients. This retrospective study was conducted in 478 patients with mandibular fractures caused by interpersonal violence over 10 years in a university clinic. The most affected were male patients (95.19%), 20–29 years of age (46.86%), under the influence of alcohol (83.26%) and without education (43.9%). The majority of mandibular fractures were displaced (89.3%) and intraorally open (64.0%). The most frequent location was the mandibular angle (34.84%). The most frequent soft tissue lesions were hematomas (45.04%) and abrasions (34.71%), being associated frequently with closed (p= 0.945/p= 0.237), displaced (p= 0.001/p= 0.002), single angle fractures (p= 0.081/p= 0.222). Educating the population and fighting alcohol consumption would decrease the occurrence of mandibular fractures through aggression. Clinical diagnosis should be made, keeping in mind that the severity of associated soft tissue lesions is directly proportional to the pattern and number of underlying fracture lines.
