Abstract:
Secondary mandibular reconstruction using fibular free flaps (FFF) is a technical challenge for surgeons. Appropriate operation planning is crucial for postoperative quality control and is notably necessary for the (re-) achievement of a physiological condylar position, and the sensible expansion and shaping of the transplant. Computer-assisted planning may help to reconstruct mandibular defects in a patient-specific and precise manner. Herein, we present a newly-developed workflow for secondary mandibular reconstruction using FFF; it comprises digital planning and in-house manufacturing to perform precise secondary mandible reconstruction. This method utilizes a newly designed positioning device to ensure the precise positioning of the fibula segments in relation to each other and the mandibular stumps. The presented in-house-printed positioning device made it possible to achieve digital planning with high precision during surgery.
摘要:
使用腓骨游离皮瓣(FFF)进行二次下颌骨重建是外科医生面临的技术挑战。适当的手术计划对于术后质量控制至关重要,并且对于(重新)实现生理髁突位置尤其必要。以及移植的合理扩展和塑造。计算机辅助计划可能有助于以患者特定和精确的方式重建下颌骨缺损。在这里,我们提出了使用FFF进行二次下颌骨重建的新开发工作流程;它包括数字计划和内部制造,以执行精确的二次下颌骨重建。该方法利用新设计的定位装置来确保腓骨段相对于彼此和下颌树桩的精确定位。所提出的内部打印定位设备使得在手术过程中实现高精度的数字规划成为可能。
