The free vascularized fibular graft is nowadays the preferred technique for pediatric mandibular reconstruction. Despite the versatility and proven efficacy for restoring the facial appearance and maxillomandibular function, those mandibular reconstructions with free vascularized fibula associate difficulties for a simultaneous restoration of the alveolar height and facial contour, which are derived from the height discrepancy between the fibula and the native mandible. In addition, the donor-site growth and morbidity are of special concern in the pediatric patient. We report a novel technique for pediatric mandibular reconstruction, in an 11-year-old girl, using a combination of a bone allograft segment with a vascularized fibular periosteal flap (VFPF), after resection of an Ewing sarcoma located at the right body of the mandible. The patient has showed optimal cosmetic, functional, and radiological outcomes, which have been maintained for 2.5 years, without detecting donor-site complications. Through this original technique, and based on the powerful osteogenic and vasculogenic properties of the pediatric VFPFs, we could effectively reconstruct a large mandibular defect providing a functional and aesthetic reconstruction, while avoiding the potential morbidity associated with the fibula resection.
游离带血管腓骨移植术如今是小儿下颌骨重建的首选技术。尽管该技术在恢复面部外观和颌骨功能方面具有通用性和已证实的疗效,但那些采用游离带血管腓骨的下颌骨重建在同时恢复牙槽高度和面部轮廓方面存在困难,这是由腓骨与天然下颌骨之间的高度差异所致。此外,供区生长和并发症在小儿患者中尤为令人关注。我们报告了一种针对一名11岁女孩的小儿下颌骨重建新技术,在切除位于右下颌骨体部的尤文肉瘤后,使用同种异体骨段与带血管腓骨骨膜瓣(VFPF)相结合的方法。该患者已显示出最佳的美容、功能和影像学效果,这些效果已维持2.5年,未检测到供区并发症。通过这种原创技术,并基于小儿VFPF强大的成骨和血管生成特性,我们能够有效重建大型下颌骨缺损,实现功能和美学重建,同时避免与腓骨切除相关的潜在并发症。
