Endoscopic skull base surgery is constantly evolving and its scope has expanded. The acquisition of surgical skills involves a long learning curve with significant risks for the patient. Therefore, training in the laboratory has become essential to achieve appropriate proficiency and reduce the morbidity and mortality associated with these procedures. The objective of our work is to develop and validate a cost-effective and easily replicable simulator for endonasal endoscopy training using a swine cadaveric model.
We used fresh Pietrain swine heads. Training exercises of increasing complexity were performed. A Specific Technical Skills and Knowledge Scale was created considering the objectives to be assessed in each task. After the simulation, the trainees were required to answer a satisfaction survey.
Ten participants were recruited (5 neurosurgery residents and 5 neurosurgeons). The simulator assessment showed statistically significant differences between groups. Performance was better among the group with endoscopic surgery experience. Face validity was assessed through a postsimulation questionnaire showing an overall mean score of 28.7 out of 30, indicating a highly positive overall assessment of the simulator. Furthermore, 100% of the trainees believe that including endoscopy training in their education would be beneficial.
The endonasal endoscopy training simulator using a swine cadaveric model is a useful and accessible tool for enhancing surgical skills in this field. It provides an opportunity for training outside the operating room, reducing the potential risks associated with patient practice, and improving the training of residents.
内镜颅底手术不断发展，其范围不断扩大。手术技能的获得涉及到一个漫长的学习曲线，患者面临着巨大的风险。因此，实验室培训对于达到适当的熟练程度和降低与这些手术相关的发病率和死亡率变得至关重要。我们的工作旨在开发和验证一种使用猪尸体模型的经济有效的、易于复制的鼻内内镜培训模拟器。
我们使用新鲜的皮特兰猪头颅。进行了越来越复杂的训练练习。根据每个任务的评估目标，创建了特定的技术技能和知识量表。模拟训练结束后，要求学员填写满意度调查问卷。
共招募了 10 名参与者（5 名神经外科住院医师和 5 名神经外科医生）。模拟器评估显示组间存在统计学显著差异。具有内镜手术经验的组表现更好。通过模拟后的问卷调查评估了表面有效性，总分为 30 分，平均得分为 28.7 分，表明对模拟器的整体评估非常积极。此外，100%的学员认为将内镜培训纳入他们的教育将是有益的。
使用猪尸体模型的鼻内内镜培训模拟器是一种有用且易于获得的工具，可以提高该领域的手术技能。它提供了在手术室外进行培训的机会，降低了患者实践相关的潜在风险，并改善了住院医师的培训。
