The aim of this study was to examine our patients who underwent accurate mandibular reconstruction with vascularized iliac crest flap using computer simulation and stereomodel and assess the postoperative results.
Fourteen patients were reviewed in this study. Bilateral iliac crests were automatically superimposed on the mandibular defects to select the optimal matching donor region in computer simulation. Operation was performed using stereomodels to replicate the preoperative planning. Actual reconstruction result was compared with computer simulation. The patients were asked to assess their satisfaction with facial appearance at 1 year after surgery.
Bony unions and good occlusion were observed, and actual results were basically in accordance with computer simulation in 14 patients. Fourteen patients reported their facial appearance to be excellent or good at 1 year after surgery.
Accurate mandibular reconstruction with vascularized iliac crest flap using computer simulation and stereomodel may achieve the ideal contour of neomandible and good function after dental rehabilitation.
本研究旨在通过计算机模拟和立体模型检查接受血管化髂嵴瓣精确下颌骨重建的患者，并评估术后结果。
本研究回顾性分析了 14 例患者。在计算机模拟中，双侧髂嵴自动与下颌骨缺损重叠，以选择最佳匹配的供区。手术采用立体模型来复制术前规划。实际重建结果与计算机模拟进行比较。术后 1 年，患者对面部外观的满意度进行评估。
14 例患者均观察到骨愈合和良好的咬合，实际结果与计算机模拟基本一致。术后 1 年，14 例患者报告其面部外观为极好或良好。
使用计算机模拟和立体模型进行精确的血管化髂嵴瓣下颌骨重建，可在牙修复后获得理想的新下颌骨轮廓和良好的功能。
