Learning suturing skills is an important area of the undergraduate curriculum and ideally requires realistic and anatomically accurate surgical training models to prepare students for treating patients. Little is currently understood regarding which model might be perceived by students to be the best or which might most effectively facilitate their learning. The aim of this study was to compare four teaching models: a tabletop silicon dental model, a restricted access tabletop model, a traditional phantom head mounted model, and a Thiel cadaver. Student preferences were explored for each of the models. Following lecture and video-based teaching 67 fourth-year students attended a practical suturing teaching session followed by the second session more focused on the experience of cutting and suturing mucoperiosteal flaps. Forty-six students (67%) gave online anonymous feedback on the first session. The majority (95%) felt prepared to place a simple interrupted suture on a patient, and 88% felt confident to do so. Twenty-eight students (40%) provided feedback on the second session with 82% agreeing that they were prepared to cut a mucoperiosteal flap and 48% felt confident to do this for a patient. The cadaver model was rated as the best of the four models for both suturing and mucoperiosteal flap skills. These results support its use for teaching students to suturing and surgical skills. However, despite this teaching student-rated confidence to cut and suture flaps for a patient remains poor.
学习缝合技能是本科课程的一个重要领域，理想情况下需要逼真且解剖结构准确的外科训练模型，以便让学生为治疗患者做好准备。目前对于哪种模型可能被学生认为是最佳的，或者哪种模型可能最有效地促进他们的学习，了解甚少。本研究的目的是比较四种教学模型：桌面硅质牙科模型、受限访问桌面模型、传统的头戴式模拟人头模型和蒂尔尸体模型。探讨了学生对每种模型的偏好。在进行讲座和基于视频的教学后，67名四年级学生参加了一次实际缝合教学课程，随后是第二次课程，该课程更侧重于切割和缝合粘骨膜瓣的体验。46名学生（67%）对第一次课程进行了在线匿名反馈。大多数人（95%）觉得自己已准备好在患者身上进行简单间断缝合，88%的人对此有信心。28名学生（40%）对第二次课程提供了反馈，82%的人表示他们已准备好切割粘骨膜瓣，48%的人觉得自己有信心为患者进行此项操作。尸体模型在缝合和粘骨膜瓣技能方面被评为四种模型中最佳的。这些结果支持将其用于教授学生缝合和手术技能。然而，尽管有这样的教学，但学生对为患者切割和缝合瓣的自信度评级仍然很低。
