通过缩短和延长方法进行牵引成骨是一种行之有效的四肢修复手术。我们使用这种技术进行下颌节段切除后的重建。一名 74 岁女性使用口内装置进行牵引成骨术，首先在 20 毫米长的节段切除后缩短下颌骨，然后以每天 0.8 毫米的速度延长，持续 21 天。分心八周后，装置被移除，并在分心部位植入牙种植体。射线照相观察显示新骨形成，种植体完全骨整合。尽管随访时间相对较短，但临床过程很顺利。采用缩短和延长方法的牵引成骨似乎是下颌骨节段切除术后重建的可行选择。
Distraction osteogenesis with the shortening and lengthening method is a well-established procedure for repairing extremities. We used this technique for reconstruction after mandibular segmental resection. A 74-year-old woman underwent distraction osteogenesis with an intraoral device, initially shortening the mandible after a 20-mm-long segmental resection, followed by lengthening at a rate of 0.8 mm per day for 21 days. Eight weeks after the distraction, the device was removed and a dental implant was placed at the site of distraction. Radiographic observation showed new bone formation, and the implant was completely osseointegrated. Although the follow-up period is relatively short, the clinical course was uneventful. Distraction osteogenesis with the shortening and lengthening method seems to be a feasible option for reconstruction after segmental resection of the mandible.
