Reconstruction of the mandibular condyle by vertical ramns osteotomy to treat osteochondroma

PURPOSE： To evaluate the clinical effects of vertical ramus osteotomy for treatment of condylar osteochondroma.METHODS： Nine patients with osteochondroma of the mandibular condyle from 2004 to 2009,treated by condylar resection and application of pedicled bone grafts gained by vertical ramus osteotomy to reconstruct the condyle,were observed and evaluated.Imaging examinations,occlusion and the function of temporomandibular joint were assessed after surgery.RESULTS： After following up for at least 8 months,good occlusion,symmetrical face,and satisfactory function of temporomandibular joint were regained.Imaging examinations showed that the upper ends of posterior ramus were in the glenoid fossa,and with time going on,it became a smooth and flat ball gradually.CONCLUSION： The posterior margin of ramus with a blood supply obtained by vertical ramus osteotomy is a relatively ideal method to reconstruct the mandibular condyle to be resected because of osteochondroma.
