OBJECTIVE
To explore the application of computed tomographic angiography (CTA) and computer aided design\manufacture (CAD\CAM) techniques in mandible reconstruction with free fibula flap.
METHODS
7 cases of complex mandible defect were reconstructed with free fibula flap. Patients' lower extremity vasculature was evaluated by preoperative CTA examination; mandible tumor resection and reconstruction were simulated by CAD technique, the surgical template was manufactured with CAM technique preoperatively; and fibula flap was shaped according to surgical template during mandible reconstruction operation.
RESULTS
Preoperative CTA examination performed without complication, the desired anatomy was adequately demonstrated in all patients. All of flaps survived, patients' facial contour are symmetry approximately.
CONCLUSIONS
CTA and CAD\CAM techniques have important value for complex mandible reconstruction in selection of donor site, planning of operation and shaping of fibula flap.
目的
探讨计算机断层血管造影（CTA）及计算机辅助设计/制造（CAD/CAM）技术在游离腓骨瓣下颌骨重建中的应用。
方法
对7例复杂下颌骨缺损患者采用游离腓骨瓣进行重建。术前通过CTA检查评估患者下肢血管情况；利用CAD技术模拟下颌骨肿瘤切除及重建，术前采用CAM技术制作手术模板；在下颌骨重建手术中根据手术模板对腓骨瓣进行塑形。
结果
术前CTA检查未出现并发症，所有患者均清晰显示出所需解剖结构。所有皮瓣均存活，患者面部轮廓基本对称。
结论
CTA及CAD/CAM技术在复杂下颌骨重建的供区选择、手术规划及腓骨瓣塑形方面具有重要价值。
