This study developed an assessment tool that was based on the objective structured assessment for technical skills principles, to be used for evaluation of surgical skills in cortical mastoidectomy. The objective structured assessment of technical skill is a well-established tool for evaluation of surgical ability. This study also aimed to identify the best material and printing method to make a three-dimensional printed temporal bone model.
Twenty-four otolaryngologists in training were asked to perform a cortical mastoidectomy on a three-dimensional printed temporal bone (selective laser sintering resin). They were scored according to the objective structured assessment of technical skill in temporal bone dissection tool developed in this study and an already validated global rating scale.
Two external assessors scored the candidates, and it was concluded that the objective structured assessment of technical skill in temporal bone dissection tool demonstrated some main aspects of validity and reliability that can be used in training and performance evaluation of technical skills in mastoid surgery.
Apart from validating the new tool for temporal bone dissection training, the study showed that evolving three-dimensional printing technologies is of high value in simulation training with several advantages over traditional teaching methods.
本研究基于客观结构化评估技术技能原则开发了一种评估工具，用于评估皮质乳突切除术的手术技能。客观结构化评估技术技能是评估手术能力的成熟工具。本研究还旨在确定制作三维打印颞骨模型的最佳材料和打印方法。
要求 24 名受训的耳鼻喉科医生在三维打印颞骨（选择性激光烧结树脂）上进行皮质乳突切除术。他们根据本研究开发的颞骨解剖工具的客观结构化评估技术技能和已经验证的综合评分标准进行评分。
两位外部评估员对候选人进行了评分，结论是颞骨解剖工具的客观结构化评估技术技能显示出一些有效性和可靠性的主要方面，可用于乳突手术技术技能的培训和绩效评估。
除了验证新的颞骨解剖工具的培训外，该研究还表明，不断发展的三维打印技术在模拟培训中具有很高的价值，与传统教学方法相比具有多个优势。
