Clinical study of virtual surgery combined with 3D-printed plates assisted free fibula flap in the repair and reconstruction of mandibular defects
Objective To evaluate the clinical effect of virtual surgery combined with 3D printing guide plate assisted fibula flap repair and reconstruction of mandibular defects.Methods Sixteen patients with maxillofacial tumors who underwent mandibular resection and fibula flap repair at the same time were selected.8 cases were assisted by the above techniques;8 cases were treated with traditional operation.The operation time,fibula flap ischemia and shaping time,bleeding volume,postoperative hospital stay,occlusion relationship and visual analogue scale(VAS)of facial appearance were compared between the two groups.The distance between bilateral condyle and mandibular angle,the length of mandibular ramus and mandibular body were measured before and after operation,and the differences between the two groups were compared.Results The operation,fibula flap ischemia and shaping time,bleeding volume and postoperative hospital stay in the above-mentioned technique-assisted group were less than those in the traditional group.The visual analogue scale(VAS)of facial appearance was higher than that in the traditional group,and the distance of mandibular landmarks before and after operation was less than that in the traditional group.The difference was statistically significant(P＜0.05).Conclusion Compared with traditional surgery,digital technology shortens the operation and remodeling time,reduces the amount of bleeding and postoperative hospital stay,and enhances the aesthetics and accuracy of mandibular defect repair and reconstruction.
