Purpose:
To report the method and effects of anatomical reduction by retro-mandibular incision and miniplate rigid fixation for condylar and subcondylar fractures.
Methods:
Twenty-four condylar neck and subcondylar fractures including 18 unilateral and 6 bilateral in 24 consecutive patients were studied. The fractures were approached by retromandibular incision and miniplate rigid fixation. Postoperative follow up was 3 to 6 months. The treatment results were evaluated including occlusion,joint functions as well as radiographic assessment of condylar changes.
Results:
The average mouth opening deviation was 6.2mm before operation, which reduced to 1.4mm 3 months after surgical treatment,3 patients had malocclusion,2 had facial nerve damages.
Conclusion:
Miniplate rigid fixation by retromandibular incision based on anatomical reduction is an effective procedure in treating severely displaced and dislocated neck of condyle and subcondylar fractures.
