To perform a validation assessment of a novel porcine ex vivo model for otoplasty training.
A total of nine otolaryngology trainees performed a standard approach otoplasty on a porcine ear. They completed a series of tasks including posterior skin incision, anterior scoring, Mustardé suture placement and concha-mastoid suture placement. Trainees completed a post-task questionnaire assessing face validity, global content validity and task-specific content validity.
Trainees' median scores for the porcine model were: 4 for face validity (interquartile range, 3-4), 5 for global content validity (interquartile range, 4-5) and 4 for task-specific content validity (interquartile range, 4-4).
This study is the first to formally validate the ex vivo porcine auricular model as a useful tool for training in otoplasty. The model should be incorporated into simulation training for otoplasty in order to improve learning, enable acquisition of specific surgical skills and improve operative outcomes.
对一种用于耳整形术训练的新型猪离体模型进行验证评估。
共有9名耳鼻喉科实习生在猪耳上进行了标准术式的耳整形术。他们完成了一系列任务，包括耳后皮肤切口、耳前划痕、Mustardé缝线置入和耳甲-乳突缝线置入。实习生完成了一项任务后问卷调查，评估表面效度、整体内容效度和特定任务内容效度。
实习生对猪模型的中位数评分分别为：表面效度4分（四分位间距，3 - 4），整体内容效度5分（四分位间距，4 - 5），特定任务内容效度4分（四分位间距，4 - 4）。
本研究首次正式验证了离体猪耳廓模型作为耳整形术训练有用工具的有效性。该模型应纳入耳整形术的模拟训练中，以促进学习、帮助掌握特定手术技能并改善手术效果。
