Abstract:

Objective To evaluate the combined application of condylectomy, sliding vertical ramus osteotomy, and mandibular contouring in treating condylar osteochondroma. Methods Eight patients with osteochondroma of the mandibular condyle were subjected to condylectomy, sliding vertical ramus osteotomy, and mandibular contouring at one stage. After the surgery, orthodontic treatment or intermaxillary fixation was applied to help treat those patients with facial asymmetry and abnormal occlusion. Results All the patients demonstrated satisfactory results. Their temporomandibular joint dysfunction, facial asymmetry, and abnormal occlusion were improved greatly. No patient developed a recurrence of the tumor during the follow-up period. Conclusion Condylectomy, sliding vertical ramus osteotomy, and mandibular contouring do not only remove the tumor, but also effectively ameliorate the facial asymmetry and abnormal occlusion of the patients as well as produce a favorable therapeutic effect.

Key words: osteochondroma of condylar, facial asymmetry, sliding vertical ramus osteotomy
