Bottom Line: Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed.The mean follow-up period was 42 months.In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.

ABSTRACT
We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery for all five patients, preserving the vertical height of the condylar process as much as possible. Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed. The mean follow-up period was 42 months. At the last follow-up visit, all patients exhibited satisfactory facial symmetry and remodeling of the remaining condyle, with stable health and no signs of recurrence. In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.

Posteroanterior (A, B) and panoramic radiographs (C-E) of the left condyle in patient 3 (circle, left condyle; arrow, menton). A, C. Preoperative radiographs show hypertrophy of the left condyle and deviation of the menton. D. Radiograph obtained on postoperative day 1. B, E. Radiographs obtained 18 months after surgery show appropriate facial symmetry and remodeling and recovery of the contour of the remaining condylar neck.

Radiographs obtained 18 months after surgery show appropriate facial symmetry and remodeling and recovery of the contour of the remaining condylar neck.

Mentions: All patients were satisfied with their facial symmetry after surgery and did not desire additional orthognathic surgery. Furthermore, the amount of mouth opening, TMJ pain and sound, and malocclusion improved in all patients. Radiographic and clinical examination was performed during the postoperative follow-up period, and all patients showed stable outcomes with no lesion recurrence at the last follow-up (average follow-up, 42 months).(Table 1, Fig. 1,2,3,4)
