摘要
背景:三叉神经痛是一种非常痛苦的疾病,可能需要采用手术方法进行治疗,通常是进行后枕骨开颅手术,然后进行微血管减压术。由于在小脑角的小三角窗进行手术时误差范围有限,而且这种病症并不常见,因此手术室可能会给外科受训人员带来困难的学习环境。我们的目标是创建一个合成的、低成本的、高保真的、基本可重复使用的模拟模型,使神经外科学员能在安全的学习环境中练习这些手术步骤:材料和方法:采用基于设计的研究方法,通过迭代微循环开发模型,并由教育和临床团队进行专家评估。该模型由易于获取的材料制成,无需先进技术,因此可持续发展、规模复制和成本都是重要的考虑因素:结果:我们的模型有效地模拟了三叉神经的逆行开颅术和微血管减压术。模型由合成材料制成的两个不同部分组成。A 部分是颅骨的一次性模制部分,而 B 部分则描绘了小脑角及其内部的一些解剖和病理结构,这些结构对实施该手术的所有步骤至关重要。A 部分与 B 部分齐平,符合人体工程学原理,两部分随后都夹在手术台上:作为概念验证,我们报告了新型、低成本、可复制的三叉神经开颅和微血管减压模拟模型的开发和使用情况。
Developing a high fidelity, low cost simulation model for retrosigmoid craniotomy and microvascular decompression of the trigeminal nerve.
Background: Trigeminal neuralgia is a very painful condition that may require a surgical approach as treatment, which is typically retrosigmoid craniotomy followed by microvascular decompression. Due to the limited margin for error when operating in the small triangular window of the cerebellopontine angle and the infrequency of this condition, the operating room can present a difficult learning environment for surgical trainees. Our aim is to create a synthetic, low-cost, high-fidelity, and largely reusable simulation model that will enable neurosurgical trainees to practice these procedural steps in a safe learning environment.
Materials and methods: Design-based research was employed to develop the model through iterative micro-cycles, with expert evaluation from an educational and clinical team. The model was made from easy to source materials without advanced technology where sustainability, reproduction at scale and cost where significant considerations.
Results: Our model effectively simulates a retrosigmoid craniotomy and microvascular decompression of the trigeminal nerve. The model consists of two distinct parts that are made of synthetic materials. Part A is a single-use, moulded portion of the skull, while part B depicts the cerebellopontine angle and some of its internal anatomical and pathological structures crucial to carrying out all the steps to this procedure. Part A sits ergonomically flush on top of Part B, with both parts subsequently clamped to the table.
Conclusions: As a proof of concept, we report the development and utilisation of a novel, low-cost, replicable retrosigmoid craniotomy and microvascular decompression of the trigeminal nerve simulation model.
期刊介绍:
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
