Mandibular reconstruction has changed significantly over the years and continues to evolve with the introduction of newer technologies and techniques.
This article reviews the history of oromandibular reconstruction, biomechanics of mandible, summarizes the reconstruction options available for mandible with defect classification, goals in reconstruction, the various donor sites, current reconstructive options, dental rehabilitation and persistent associated problems.
Oromandibular reconstruction, although a challenge for the head and neck reconstructive surgeon, is now reliable and highly successful with excellent long-term functional and aesthetic outcomes with the use of autogenous bone grafts and current reconstructive options. The ideal reconstruction would provide a solid arch to articulate with the upper jaw, restoring swallowing speech, mastication, and esthetics. Autogenous vascularized bone grafts in combination with microsurgical techniques have revolutionized mandibular reconstruction in oral cancer surgery. Current trends in mandibular reconstruction aim to achieve reestablishment of a viable mandible of proper form and maxillary mandibular relationship while decreasing the need for invasive autogenous graft procurement. However the optimal reconstruction of mandibular defects is still controversial in regards to reconstructive options which include the donor site selection, timing of surgery and method of reconstruction.
多年来,下颌骨重建发生了显著变化,并且随着更新技术和技巧的引入仍在不断发展。
本文回顾了口腔颌面部重建的历史、下颌骨的生物力学,总结了下颌骨缺损分类的重建选择、重建目标、各种供区、当前的重建选择、牙列修复及持续存在的相关问题。
口腔颌面部重建虽然对头颈重建外科医生来说是一项挑战,但如今通过使用自体骨移植和当前的重建选择,已变得可靠且非常成功,能取得优异的长期功能和美学效果。理想的重建应提供一个坚实的牙弓以与上颌骨相连,恢复吞咽、言语、咀嚼及美观。带血管蒂的自体骨移植联合显微外科技术彻底改变了口腔癌手术中的下颌骨重建。下颌骨重建的当前趋势旨在重建一个形态合适且具有正常上下颌关系的有活力的下颌骨,同时减少对侵入性自体骨获取的需求。然而,关于重建选择,如下颌骨缺损的最佳重建在供区选择、手术时机及重建方法等方面仍存在争议。
