運用高擬真電腦顳骨模擬器於醫學生顳骨解剖教育－成效初探

背景與目的：高擬真醫學教育已漸趨重要，尤其運用在立體構造複雜的顳骨解剖教學上時特別實用。我們利用電腦顳骨模擬器，其包含高解析的3D立體顳骨圖片及手術模擬軟體，結合力回饋設備來感受研磨過程的施力與聲音，來了解高擬真電腦顳骨模擬器在醫學生學習上的角色。研究方法：18名輪派至耳鼻喉科之醫學生，分成兩組：傳統教學組5位，模擬器教學組13位。所有醫學生受試者於第一天先接受顳骨解剖構造口試，接著接受顳骨解剖構造的課程，並講解研磨顳骨步驟。模擬器教學組受試者使用模擬器，先熟悉模擬器操作方式與技巧，接著研磨電腦顳骨1次。所有醫學生在離開耳鼻喉科輪派前（第14天）接受顳骨解剖構造的筆試。研究結果：醫學生在「顳骨解剖構造前測」與「顳骨解剖構造後測」成績，傳統教學組與模擬器教學組在前測部分，兩組成績相當；後測部分，模擬器教學組平均成績明顯高於傳統教學組。結論：高擬真電腦顳骨模擬器值得運用在顳骨解剖構造教學上，成效更優於傳統課堂教學。

Simulation has become an important teaching format in medical education; it is especially useful to teach complex anatomy of temporal bone (TB). We utilized a TB simulator, to consist of: 1. Software with high resolution 3D TB volumetric images. 2. haptic device from which the user can sense the force feedback and the sound of drilling. Aims of this study are to evaluate and to compare the effectiveness of TB simulator in medical student teaching. Methods: A total of 18 rotating medical students were randomly assigned to the ＂simulation＂ (N=13) or ＂traditional＂ (N=5) TB training groups. Both groups were oriented with TB anatomy and dissection procedures by slide presentation and didactic lecture. The ＂simulation＂ group practiced on the simulator to complete 1 session of TB dissection. Oral examinations were given at day 0 and written examinations were given on day 14. Using paired t-test, the before-after test scores were compared between ＂simulation＂ and ＂traditional＂ groups. Results: Both groups showed significant improvement in their comprehension to TB anatomy. The written examination showed that the ＂simulation＂ group had significantly greater magnitude of improvement than ＂traditional＂ group. Conclusions: The test results confirm that the 3D, virtual technology, and haptic simulator might be a worthwhile and superior substitute to traditional class-based lecture in teaching TB anatomy.
