摘要：

背景：岩骨解剖形态和空间构筑关系复杂，手术教学难度大。计算机虚拟现实技术因其高效、直观、交互性等优点，用于岩骨手术解剖教学开发潜力巨大。
目的：评估虚拟现实技术建立岩骨三维解剖模型在岩骨手术教学中的价值。
方法：1例非颅底病变患者头颅CT Dicom格式数据导入虚拟现实工作站进行三维重建，利用工作站中的图像处理软件提取岩骨表面和内部解剖结构图像，构建岩骨三维解剖模型。选取志愿者40名随机分为2组，每组20名，受试组安排阅读教科书结合虚拟影像模型观察，对照组仅安排阅读教科书。在学习后1，2周分别进行相关解剖知识笔试和图谱标识测试。
结果与结论：岩骨虚拟现实解剖模型可视化效果良好。学习后1周测试，受试组解剖知识笔试和图谱标识成绩高于对照组，差异有显著性意义(P < 0.05)。学习后2周测试，受试组解剖知识笔试与对照组差异无显著性意义(P > 0.05)，受试组图谱标识成绩高于对照组，差异有显著性意义(P < 0.05)。结果显示虚拟现实三维影像模型用于岩骨手术解剖教学效果良好。

Abstract:

BACKGROUND: Surgical education assignment of petrous bone is difficult for the complexity of anatomic morphology and stereo architecture relationship. Merits including efficient, objective, and interactive exist in computed virtual reality technology, of which the development potential is enormous for the surgical education of prtrous bone.
OBJECTIVE: To evaluate the application value of virtual reality technique in the surgical education of petrous bone.
METHODS: The Dicom data of CT scan performed for one case without skull base disease was transferred to the virtual reality system to reconstruct three-dimensional image, and then, the images of structures in the osseous tubes and impressions of petrous bone were extracted to build three-dimensional anatomy model by using the software of image process. Forty volunteers were divided randomly into two groups with 20 members in each group respectively. The examined group had assignment of both textbook reading and image model observation. The control group had only task of textbook reading. Scoring about accuracy for written test of anatomy knowledge and marking of anatomic illustration was employed after 1 week and 2 weeks of study to evaluate the educational effect.
RESULTS AND CONCLUSION: Effect of three-dimensional visualization was well for petrous bone model. Testing was performed after 1 week study, the scores of written test and illustration marking in the examined group were higher than those in the control group. Significant difference existed in the score of written test and illustration marking between two groups (P < 0.05). After 2 weeks study, there was no significant difference in the score of written test between two groups (P > 0.05). However, the illustration marking score of examined group was significantly higher than that of control group, and there was significant difference of illustration marking score between two groups (P < 0.05). The virtual reality three-dimensional model has good advantages in the surgical education of petrous bone.
