This study aimed to develop and evaluate a low-cost orbital prosthesis for simulation of endoscopically assisted intra-orbital anterior ethmoidal artery ligation.
A low-cost orbital prosthesis was built and evaluated by ENT surgical trainees. Feedback was given following the assessment in the form of a face validity questionnaire.
Results were scored on a Likert scale of 1-7 (low to high). Trainees had limited exposure to the procedure (40 per cent) and predominantly low levels of confidence (mean, 3.67) that correlated with a lack of first-hand experience. The anatomy and likeness to human tissue of the prosthesis were both ranked highly, with mean scores of 5.0 and 4.93, respectively.
The results of this study support the idea that a simple anatomical prosthesis for the simulation of endoscopic anterior ethmoidal artery ligation can be created with potential value to otolaryngology surgical training. To the authors' knowledge, this is the first documentation of simulated surgical epistaxis management using an artificial anatomical model.
本研究旨在开发和评估一种低成本的眼眶假体，以模拟内窥镜辅助眶内筛前动脉结扎术。
由耳鼻喉科外科受训人员对低成本眼眶假体进行构建和评估。通过面部有效性问卷调查的形式提供反馈。
结果按 1-7 分（低至高）评分。受训者对该手术的接触有限（40%），且信心水平普遍较低（平均 3.67），这与缺乏第一手经验相关。假体的解剖结构和与人组织的相似性均被评为高分，分别为 5.0 和 4.93。
本研究结果支持这样一种观点，即可以创建一种用于模拟内窥镜筛前动脉结扎术的简单解剖假体，这对耳鼻喉科手术培训具有潜在价值。据作者所知，这是首次使用人工解剖模型记录模拟手术性鼻出血管理。
