To create a 3-dimensional (3D) educational computer model of the larynx, to assess the feasibility of this learning module on a Web-based platform, and to obtain student feedback on the module.
Male and female adult cadaveric necks were scanned with microcomputed tomographic and magnetic resonance imaging scanners. Key structures were identified on each slice of the computed tomogram and/or magnetic resonance image and analyzed with a segmentation software package. Then, the images were exported into Microsoft Powerpoint. Visual text and audio commentary were added. Real cases of a child's larynx, an adult with a tracheostomy, and a patient with laryngeal carcinoma were included. The computer module was launched on a password-protected, Web-based platform.
Fifty-eight first-year medical students (38% male; mean [SD] age, 23 [1.8] years) were invited to evaluate the module and to complete a survey.
Most students thought that the 3D computer module was effective (60%), clear (66%), and user friendly (72%); most students (81%) thought that it was easier to understand laryngeal anatomy when they could visualize it in 3D; and most students (83%) said that they would like lectures better if they were supplemented with 3D computer modules.
A 3D educational computer model of the larynx has been successfully created and warmly received by medical students.
创建一个喉部的三维（3D）教育计算机模型，评估该学习模块在基于网络的平台上的可行性，并获得学生对该模块的反馈。
使用微型计算机断层扫描和磁共振成像扫描仪对成年男性和女性尸体的颈部进行扫描。在计算机断层扫描图像和/或磁共振图像的每一层上识别关键结构，并用分割软件包进行分析。然后，将图像导出到Microsoft Powerpoint中。添加了视觉文本和音频评论。纳入了儿童喉部、成年气管切开患者和喉癌患者的真实病例。该计算机模块在一个受密码保护的基于网络的平台上启动。
邀请了58名一年级医学生（38%为男性；平均[标准差]年龄，23[1.8]岁）评估该模块并完成一项调查。
大多数学生认为3D计算机模块有效（60%）、清晰（66%）且用户友好（72%）；大多数学生（81%）认为当他们能够以3D形式可视化喉部解剖结构时，更容易理解；大多数学生（83%）表示，如果讲座辅以3D计算机模块，他们会更喜欢。
已成功创建了一个喉部的3D教育计算机模型，并受到医学生的热烈欢迎。
