The cleft patient may present with significant maxillary deficiency requiring maxillary advancement to establish balanced facial form and function. Often these skeletal advancements require movement of the maxilla of more than 10 mm. The cleft patient poses special challenges because of difficulty of mobilizing tissues on a multiply operated maxilla, as well as long-term stability. Distraction osteogenesis is a technique that may be applied to help move the maxilla over a long distance and slowly expand the soft tissues. A discussion of the orthodontic and surgical considerations when planning and executing the technique is presented.
腭裂患者可能存在明显的上颌骨发育不足，需要进行上颌骨前移以建立面部形态和功能的平衡。通常，这些骨骼前移需要上颌骨移动超过10毫米。由于多次手术的上颌骨上组织难以移动以及长期稳定性问题，腭裂患者面临特殊挑战。牵张成骨术是一种可用于帮助上颌骨远距离移动并缓慢扩张软组织的技术。本文讨论了在规划和实施该技术时的正畸和手术注意事项。
