目的：生成和描述的过程中创建一个3D打印，快速原型颞骨模型从临床质量CT images.Materials和方法：我们描述了一种技术，创建一个准确的，可变的，可重复的快速原型颞骨模型，使用免费提供的软件来分割临床CT数据，并生成三个不同的3D模型组成的ABS塑料。每个模型进行了评估的基础上的外观和尺寸的解剖结构和响应手术drilling.Results：乳突气室保留了支架材料在最初的版本。这需要修改模型，以允许脚手架材料的排水。外耳道尺寸与临床数据测量的相似。在所有模型中识别出锤骨、砧骨、卵圆窗、圆窗、岬、水平半规管和面神经管乳突段。两个模型中镫骨仅部分形成，第三个模型中没有。ABS塑料的定性感觉比骨软。结论：我们提出了一个快速原型颞骨模型的基础上，临床CT数据，使用3D打印技术。该模型可以快速和廉价地制造，足以用于教育培训。(C)2015 Elsevier Inc.

Purpose: Generate and describe the process of creating a 3D printed, rapid prototype temporal bone model from clinical quality CT images.Materials and methods: We describe a technique to create an accurate, alterable, and reproducible rapid prototype temporal bone model using freely available software to segment clinical CT data and generate three different 3D models composed of ABS plastic. Each model was evaluated based on the appearance and size of anatomical structures and response to surgical drilling.Results: Mastoid air cells had retained scaffolding material in the initial versions. This required modifying the model to allow drainage of the scaffolding material. External auditory canal dimensions were similar to those measured from the clinical data. Malleus, incus, oval window, round window, promontory, horizontal semicircular canal, and mastoid segment of the facial nerve canal were identified in all models. The stapes was only partially formed in two models and absent in the third. Qualitative feel of the ABS plastic was softer than bone. The pate produced by drilling was similar to bone dust when appropriate irrigation was used.Conclusion: We present a rapid prototype temporal bone model made based on clinical CT data using 3D printing technology. The model can be made quickly and inexpensively enough to have potential applications for educational training. (C) 2015 Elsevier Inc. All rights reserved.
