Objective:
This retrospective study presents the type of osteosynthesis used for the fixation of condylar fractures and the postoperative results and complications observed.
Method And Materials:
Forty-five patients with fractures of the mandibular condyle underwent open reduction and osteosynthesis with plates and screws. The surgical approach was, in most cases, via a submandibular incision. Stabilization was achieved in the majority of the cases with a 2.0-mm single or double miniplate, but 2.0-mm mini dynamic compression plates were also used.
Results:
The complications were mainly inadequate reduction, screw loosening, and limitation of mouth opening. No plate fractures or infections were observed.
Conclusion:
The use of a single plate (miniplate or dynamic compression plate) often produces inadequate stability and reduction postoperatively. The placement of two 2.0-mm zygomatic dynamic compression plates demands great tissue dissection and detachment and can lead to limitation of mouth opening. The use of two 2.0-mm miniplates seems to produce better stability and fewer complications.
