It is recognized that the mandibular reconstruction with free flap allows for both functional and aesthetic restoration. The flap must be used for reconstruction of a smooth lower mandibular contour and also the alveolar bone to allow dental rehabilitation. The double-barrel fibula free flap does respond well to these imperatives, but it increases risk of vascular complications. To overcome these risks, we propose a single-barrel fibula free flap, positioned at the alveolar level and a customized 3D implant, designed by computer-assisted surgery, at the basilar level. The interest of the single-barrel fibula associated with a customized 3D implant compared to the double-barrel fibula free flap is twofold: it decreases the vascular risks associated with the plication of the second pedicle and allows patients to have a pedicle of greater length. It also allows them to have a good cortical bone placed in the alveolar bone to rehabilitate the mastication function.
人们认识到,游离皮瓣下颌骨重建既能实现功能重建,也能实现美学重建。皮瓣必须用于重建光滑的下颌轮廓和牙槽骨,以实现牙齿修复。双段腓骨游离皮瓣能够很好地满足这些要求,但会增加血管并发症的风险。为了克服这些风险,我们提出了一种单段腓骨游离皮瓣,置于牙槽骨水平,并使用计算机辅助手术设计定制的 3D 种植体,置于基底部。与双段腓骨游离皮瓣相比,单段腓骨联合定制 3D 种植体的优势有两点:它降低了与第二个蒂折叠相关的血管风险,并允许患者拥有更长的蒂。它还可以使患者获得良好的皮质骨置于牙槽骨中,以恢复咀嚼功能。
