PurposeTo present a series of cases of mandibular symphysis fractures treated at our institution with a 3-dimensional strut plate. The aim of this study is to confirm the stability of this fixation technique, and discuss its advantages, disadvantages, and potential complications.MethodsThe investigators designed and implemented a retrospective cohort study composed of patients operated on by the same surgeon at our institution between July 2012 and April 2014 who had suffered a mandible fracture with a symphysis component. Patients were evaluated to identify aspects of occlusion, fracture mobility, postoperative infection, and the need for hardware removal.ResultsThe sample was composed of 12 subjects who met inclusion criteria. This required the fracture be linear and non-comminuted, there be sufficient distance from the mental foramina, a maximum of 5 days between the trauma and the surgery, and a minimum postoperative period of 3 months. The mean age of the sample was 33.4 years; and 8.3% of the patients enrolled were female (1/12). Ten subjects did well. Two subjects developed surgical site infection, one of whom had nonunion as well requiring additional fixation.ConclusionThe results of this study suggest a 3-dimensional strut plate applied to symphysis fractures provides adequate fracture stabilization with a risk of complications that is comparable to more traditional fixation methods. In addition, there exists an added advantage of minimal manipulation and adaptation that may hasten overall operating time.
