The aim of the study was to compare two types of mandible reconstructive operations with scapula and fibula free flaps: procedures with 3-D models from thermoplastic materials and conventional planning surgeries. 8 patients were treated due to an advanced oral cavity squamous cell carcinoma. In four patients with a mandibular defect, a physical 3-D model consisting of the reconstructed and unaffected sites was prepared for a reconstruction protocol. The 3-D models were designed based to high resolution CT scans. Assessment of comparative functionality (stability of junction, mobility, mastication ability) and cosmetics was examined in both groups, following a 8 weeks healing period with better results in group with 3D model. 3-D models for mandible and donor bones allow to obtain better functionality of restored mandible in comparison to the traditional method also significantly decreases time of the operation and allows to achieve the desired shape and esthetic effect within the 1/3 of the lower face.
使用热塑材料 3D 模型的手术与传统规划手术。由于口腔鳞状细胞癌晚期，8 名患者接受了治疗。在 4 名下颌骨缺损患者中，为重建方案准备了由重建和未受影响部位组成的物理 3D 模型。3D 模型是根据高分辨率 CT 扫描设计的。在 8 周的愈合期后，两组患者都进行了功能（交界处稳定性、活动度、咀嚼能力）和美容评估，3D 模型组的结果更好。下颌骨和供骨的 3D 模型可使重建下颌骨获得更好的功能，与传统方法相比，还显著缩短了手术时间，并允许在下半脸的 1/3 内达到所需的形状和美观效果。
