Currently, volunteers and/or anatomical models are used for teaching oncoplastic surgery marking. However, as the breast is an intimate organ, recruiting volunteers is difficult, and the available droopy breast models have limitations. We evaluated the feasibility of a novel Marking Breast Oncoplastic Surgery Simulator (MBOSS) for the teaching of marking.
Breast/plastic surgeons/trainees, grouped according to their oncoplastic experience, were randomized to MBOSS or volunteer. All had a pre-test evaluation prior to receiving hands-on training in inverted T mammoplasty marking in their randomized group, followed by an assessment of their marking skills, by an examiner blinded to their group assignment. All participants then underwent post-test and course evaluations, and those who used MBOSS for training, also evaluated MBOSS realism. Learning outcomes between the two groups were compared using the Kirkpatrick educational model.
Forty participants were enrolled. Demographics, baseline oncoplastic experience and pre-test results were comparable between the MBOSS and volunteer groups. For Kirkpatrick level 1 satisfaction outcomes, the two groups did not differ significantly. For level 2 knowledge assessment, MBOSS post-test scores were significantly higher (P=0.0471). For level 3 skill application and level 4 organizational impact evaluated 6 months post course, there were no significant differences between the groups. Although MBOSS may not mimic the breast completely, 95% of MBOSS-trained participants rated MBOSS as a good training tool and 85% would use MBOSS instead of a volunteer.
MBOSS learning outcomes are comparable to outcomes using volunteers, making MBOSS an alternative for teaching oncoplastic surgery marking.
目前，整形手术标记教学采用志愿者和/或解剖模型。然而，由于乳房是一个私密器官，招募志愿者困难，且现有的下垂乳房模型存在局限性。我们评估了一种新型的乳房整形手术标记模拟器（MBOSS）用于标记教学的可行性。
根据整形手术经验将乳房外科医生/整形外科医生/实习生分组，随机分为使用MBOSS组或志愿者组。所有参与者在随机分组后接受倒T形乳房成形术标记的实践培训前进行预测试评估，然后由对其分组不知情的考官评估其标记技能。所有参与者随后进行后测试和课程评估，使用MBOSS进行培训的参与者还评估了MBOSS的逼真度。使用柯克帕特里克教育模型比较两组的学习成果。
共招募了40名参与者。MBOSS组和志愿者组在人口统计学、基线整形手术经验和预测试结果方面具有可比性。对于柯克帕特里克一级满意度结果，两组无显著差异。对于二级知识评估，MBOSS后测试分数显著更高（P = 0.0471）。对于课程结束6个月后评估的三级技能应用和四级组织影响，两组之间无显著差异。尽管MBOSS可能无法完全模拟乳房，但95%使用MBOSS培训的参与者将MBOSS评为良好的培训工具，85%的人会选择使用MBOSS而非志愿者。
MBOSS的学习成果与使用志愿者的结果相当，使MBOSS成为乳房整形手术标记教学的一种替代方法。
