    Abstract: 對於下顎骨發生缺損的病患,整形外科醫師通常會使用腓骨游離皮瓣來進行重建,為了重塑下顎骨原有的外觀,我們需要將腓骨切割成不同長度的片段,組合成近似下顎曲線的外觀。而考慮骨骼癒合的速度,能夠建立緊密的骨間吻合面是相當合理的要求。因此,如何建構一個良好的手術計畫與提供可靠的工具來協助骨骼切割是非常重要的。下顎骨重建手術的成功關鍵在於,能夠提供手術者一套可靠而正確的方法,將下顎骨缺損的空間資訊傳遞到腓骨上,以便讓他們做為切割腓骨的參考。關於這個問題先前有許多學者提出解決方案,然而並沒有一個簡便而好用的方法。
    ;For patients with intraoral defects which involve the mandible, plastic surgeons often use free fibular flaps for reconstructions. To restore the native curvature of the mandible, the fibula bone has to be cut into different sized segments. Considering the speed of bone healing, it is reasonable that good bone-to-bone contact will improve bone union. Therefore, a comprehensive plan and a stable guide for osteotomies are essential. The key to a successful mandibular reconstruction is to accurately and properly transmit the spatial information of mandible defect to the fibula. Different methods have been proposed; however, better solutions are still needed.
    To improve the surgical outcome we tried to develop two methods for increasing the accuracy of fibula osteotomies. We used computer-aided design technology to produce a paper model which is similar to the shape of patient’s mandible, and used the model as reference for performing fibula osteotomies. This method then inspired us about the formation of metallic mechanical device(s) to help surgeons intraoperatively measure the mandible defect, design the ideal shape of fibula bone flap and perform precise osteotomies. The paper model method was applied in 6 patients and the mechanical device method was used for the reconstruction of 12 patients. Well matched bone-to-bone contact surfaces were achieved in these patients. Further applications of these methods may include: the combination these two methods together for secondary mandibular reconstructions and the use of mechanical device(s) with custom-made surgical stent for optimize the ideal lengths and beveling angles of bone segments. In this study we present the development and use of two novel fibula osteotomy guides, paper model and mechanical device, for mandibular reconstructions. Under different circumstances, these two methods can be utilized separately or combined together for the best surgical results.
