摘要：

Midface osteotomy was performed on 5 young adult sheep aged 10-12 months. In 4 animals midface advancement by gradual distraction was performed using an external device; one animal served as a control. The midface was advanced by 2 mm per day for 21 days. The amount of advancement was 36 mm in the nasofrontal area and 43 mm on the lateral aspect of the maxilla. After the period of active distraction the midface was maintained with external fixation for an additional 6 weeks to allow for ossification. Radiographs were obtained immediately postoperatively, after 21 days of distraction, and at the end of the 6 week fixation period. New bone formation in the distracted area was obvious radiographically, clinically and histologically. In conclusion, midface advancement by osteotomy and gradual distraction is possible in the sheep model and may offer controlled correction of deformity, obviating the need for bone grafting.
