Aim. Mandibular fractures constitute a substantial proportion of cases of maxillofacial trauma. This study investigated the incidence, causes and treatment of mandibular fractures at the Department of Maxillo-Facial Surgery in Florence.
Methods. The clinical records and radiographs for 465 patients treated for mandibular fracture at the Department of Maxillo Facial Surgery of Florence over a sixteen years period (from 1990 to 2006) were reviewed. Data on the patients’ age, sex, smoking status, alcohol and drug use, mechanism of injury were recorded and assessed.
Results. Men 20 to 37 years of age sustained the most mandibular fractures. The ratio of males to females was 5:1. Most fractures were caused by violent assault (51.5%), followed by motor vehicle accidents (22.5%) and sports activity (11.5%). Alcohol was a contributing factor at the time of injury in 21.7% of fractures for which this information was available.
Conclusion. The incidence and causes of mandibular fracture reflect trauma patterns within the community and, as such, can provide a guide to the design of programs geared toward prevention and treatment. In the last decades it has been recorded an increment of mandibular fractures due to trauma resulting from violence.
