Purpose:
We present a series of cases of mandibular symphysis fractures treated at our institution with a 3-dimensional strut plate. The aim of the present study was to confirm the stability of this fixation technique and discuss its advantages, disadvantages, and potential complications.
Patients And Methods:
We designed and implemented a retrospective cohort study of patients who underwent surgery by the same surgeon at our institution from July 2012 to April 2014 for a mandible fracture with a symphysis component. The patients were evaluated to identify aspects of occlusion, fracture mobility, postoperative infection, and the need for hardware removal.
Results:
The sample included 12 subjects who had met the inclusion criteria. The inclusion criteria were a linear noncomminuted fracture, sufficient distance from the mental foramina, a maximum of 5 days between the trauma and surgery, and a minimum postoperative period of 3 months. The mean age of the sample was 33.4 years, and 1 of the 12 patients (8.3%) was female. Of the 12 patients, 10 did well, and 2 developed a surgical site infection, 1 of whom also experienced nonunion and required additional fixation.
Conclusions:
The results of the present study suggest a 3-dimensional strut plate applied to symphysis fractures provides adequate fracture stabilization with a risk of complications comparable to that of more traditional fixation methods. In addition, the technique has the added advantage of minimal manipulation and adaptation, which could shorten the overall operating time.
