BACKGROUND: Bilateral body mandibular fractures (BBMF) are unusual in an adult dentate population. On the other hand, it is the most common site of fracture in edentulous mandibles. This is the first study that compares and discusses the management of BBMF in dentate and edentulous patients.
METHODS: Data regarding patients with maxillofacial fractures in the Division of Maxillofacial Surgery, Città della Salute e della Scienza Hospital, Turin, Italy were analysed retrospectively for the period between January 2001 and December 2017.
RESULTS: Between 2001 and 2017, 1109 patients with 1712 mandibular fractures were admitted in our division. Mandibular body fractures affected 180 patients and 21 out of 180 patients suffered BBMF (5 dentates and 16 edentulous). In dentate group, 4 males and 1 female, mean age 29 years, the BBMF were caused by high velocity impacts, whereas in edentulous group, 6 males and 10 females, mean age 72 years, the main cause was falls. All dentate patients were treated with open reduction and internal fixation using 1.0 mm plates and all edentulous patients using 2.0 mm titanium locking reconstruction plates or 1.0 mm plates according to their atrophy stage.
CONCLUSIONS: In the dentate population BBMF are rare, caused by high energy impacts only and occurred in a younger patients respect to the edentulous population in which the fractures were more frequent and caused mainly by falls. Open reduction and internal fixation using 1.0 mm plates or 2.0 mm titanium locking reconstruction plates was the method of choice in all patients with bilateral body mandibular fractures.
