Comparison of the clinical effects of treatment of osteochondroma by two types of vertical ramus osteotomy

The purpose of this retrospective study was to evaluate 10 patients with osteochondroma of the mandibular condyle who were treated by vertical ramus osteotomy. Three patients had resection of the condyle and reconstruction with free vertical ramus osteotomy grafts (free graft group) and seven had pedicled vertical sliding ramus osteotomy grafts (pedicled graft group). The mean (range) observation period was 30 months. All patients had satisfactory clinical outcomes, and facial symmetry and good occlusion were achieved during the first 10 months.
