Oncologic maxillectomy defects requiring bony reconstruction are among the most challenging head and neck cases because of the complex three-dimensional geometry of the midface. Virtual surgical planning technology is advantageous in these cases because it provides superior positional precision and accuracy compared with traditional techniques and facilitates prosthodontic rehabilitation. Maxillary cancer recurrence after an initial fibula flap reconstruction presents a unique challenge. The authors report the first two cases of sequential fibula flaps after second or recurrent cancer of the maxilla. Virtual surgical planning facilitated resection with adequate tumor margins, optimized anatomic positioning of the fibula construct with three-dimensional printed plates, and enabled immediate functional dental implant placement.
需要进行骨重建的肿瘤上颌骨缺损是头颈部最具挑战性的病例之一,因为中面部的三维几何形状非常复杂。虚拟手术规划技术在这些情况下具有优势,因为与传统技术相比,它提供了更高的位置精度和准确性,并促进了修复体的康复。初次腓骨瓣重建后上颌骨癌症复发是一个独特的挑战。作者报告了首例上颌骨第二次或复发性癌症后连续使用腓骨瓣的两例病例。虚拟手术规划有助于进行足够的肿瘤边缘切除,优化了三维打印板的腓骨结构的解剖定位,并能够立即进行功能性牙种植体植入。
