The mandible is an important component of the orofacial skeleton, and resection of part of the mandible as part of head and neck oncological procedures can have dramatic impact on both function and cosmesis. In this article, we describe a new technique in the resection osteotomy and flap fixation that improves the stability and aesthetic outcome of the reconstruction. The mandibular resection is performed utilizing a horizontal osteotomy above the mandibular angle on one side and a stepped body or angle osteotomy on the other side. Our technique is unique as it allows flexibility in adjusting the chin point projection to give the best possible aesthetic outcome; it allows more bone-to-bone contact, which increases the stability; it reduces rotation; and it allows for use of miniplate fixation, facilitating future rehabilitation with implants. We have been using this technique with great success in our hospital, and we recommend its use for its improved flexibility, stability, and aesthetic outcome.
下颌骨是颌面骨骼的重要组成部分，作为头颈肿瘤手术的一部分，切除部分下颌骨会对功能和美观产生巨大影响。在本文中，我们描述了一种新的切除截骨术和皮瓣固定技术，该技术可提高重建的稳定性和美学效果。下颌骨切除术通过在一侧下颌角上方进行水平截骨术，在另一侧进行阶梯状体部或角部截骨术来完成。我们的技术独特之处在于，它可以灵活调整颏点投影，以获得最佳美学效果；它允许更多的骨对骨接触，从而增加稳定性；它减少了旋转；并且它允许使用微型钢板固定，便于未来进行种植体修复。我们在医院一直成功地使用这种技术，并且由于其灵活性、稳定性和美学效果的提升，我们推荐使用该技术。
