中文摘要   隨著醫療技術的進步與人們對整形手術接受程度的提昇,人們為了使自己變得更漂亮、活得更有自信而進行整形手術的情形已經越來越普遍。整形醫師就像一個可提供客製化外表的廠商,將消費者想像中的模樣製作出來。然而一個成功的顏面整形手術必須在手術前與病人經過詳盡的溝通及縝密規劃,執刀的醫師除了要有豐富的臨床經驗外,還要具備良好的審美觀及術後外觀結果的預測能力。但是經常因為整形醫師與整形者溝通不良、對整形目標認知的落差等因素而使手術不盡理想,甚至引起醫療糾紛。
  
  隨著電腦圖學的相關技術日益成熟,已有相當多利用電腦來輔助手術進行的研究與應用而本研究將針對顏面整形手術術前計劃的部份進行研究,在研發的初期以雙眼皮整形手術為例進行術前計劃系統的開發。本研究結果開發出一套將提供整形醫師在診所諮詢時以低成本高效率的情況下重建整型者的臉部手術區的三維模型、手術切割線的模擬繪製,以及手術完成後外觀動態模擬與預測。最後並且以一位單眼皮的受測者運用本研究所開發的系統軟體進行案例實作與系統程式測試,實作效果良好。
英文摘要   It is very popular and popular for people doing facial surgery for expecting to become more beauty and increase their confidence, due to the improvement in medical treatment technology and the increase in the acceptance of facial surgery for people. A plastic surgeon can be considered as a factory owner who can provide a customized appearance, which is imaged or specified by a customer. But a successful facial surgery should be completed under a detailed communication between patient and plastic surgeon and careful planning. The operation executor not only should have plentiful clinical experience but also should have good sense of appreciation of the beauty and the power of anticipating the patient’s appearance after operation. But a lot of failure cases were usually found due to ill communicated and/or bad medical skill. Along with the gradually matured computer graphic technology, a lot of investigations and applications of computer-assisted surgical operation have been proposed.
  
  The purpose of this study is to construct a computer-assisted facial surgery system, which can be used by the physician to communicate with the patient using a computer in the cosmetic clinic before the cosmetic surgery. This system will contain the functions of 3D facial data reconstruction, virtual surgical operation, and appearance simulation after operation based on biomechanics. With the aid of this system, the medical dispute due to ill-communicated will be reduced.
