摘要

介绍:三维打印颞骨模型可用于复杂耳科手术的训练和演练。迄今为止,还没有关于三维打印颞骨模型开发过程的整合文献。对现有文献的简要回顾表明,颞骨的许多关键手术标志在模型中的表现不佳。本研究旨在提出一种新颖的设计和制作工作流程,以制作用于手术模拟的高保真三维打印颞骨模型:方法:概述了数据提取、三维分割、计算机辅助设计(CAD)和制作的开发阶段。阐述了乳突气室和面神经走向等关键解剖区域的设计和制作注意事项,以及采用的相关策略和设计方法。为了验证模型,对放射学测量结果进行了比较,并由一位资深耳鼻喉科医生在模型上进行了各种手术操作:结果:原始扫描和模型扫描之间的测量结果表明,模型的精确度达到了亚毫米级。资深耳科医生的评估发现,该模型在模拟多种手术过程方面令人满意:本研究提供了一种系统方法,用于创建精确的三维打印颞骨模型,以进行手术培训。结果表明,该模型在模拟手术过程方面具有很高的准确性和有效性,有望改善培训效果和患者预后。

Developing a production workflow for 3D-printed temporal bone surgical simulators.

Introduction: 3D-printed temporal bone models enable the training and rehearsal of complex otological procedures. To date, there has been no consolidation of the literature regarding the developmental process of 3D-printed temporal bone models. A brief review of the current literature shows that many of the key surgical landmarks of the temporal bone are poorly represented in models. This study aims to propose a novel design and production workflow to produce high-fidelity 3D-printed temporal bone models for surgical simulation.

Methods: Developmental phases for data extraction, 3D segmentation and Computer Aided Design (CAD), and fabrication are outlined. The design and fabrication considerations for key anatomical regions, such as the mastoid air cells and course of the facial nerve, are expounded on with the associated strategy and design methods employed. To validate the model, radiological measurements were compared and a senior otolaryngologist performed various surgical procedures on the model.

Results: Measurements between the original scans and scans of the model demonstrate sub-millimetre accuracy of the model. Assessment by the senior otologist found that the model was satisfactory in simulating multiple surgical procedures.

Conclusion: This study offers a systematic method for creating accurate 3D-printed temporal bone models for surgical training. Results show high accuracy and effectiveness in simulating surgical procedures, promising improved training and patient outcomes.
