Plate osteosynthesis of condylar fractures: a retrospective study of 45 patients.
OBJECTIVE
This retrospective study presents the type of osteosynthesis used for the fixation of condylar fractures and the postoperative results and complications observed.


METHODS
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.


CONCLUSIONS
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.
