Though live porcine models have been utilized as microsurgical training models, significant drawbacks limit their use. We recently developed a latex-perfused, nonliving, porcine abdomen perforator dissection simulation and described its anatomic similarity to the human deep inferior epigastric artery flap. The purpose was to assess the change in resident confidence in performing key operative steps of flap elevation and perforator dissection and obtain feedback on model realism and utility.<\/jats:p><jats:p>\n          Methods\u2003Seventeen plastic and reconstructive surgery resident physicians (postgraduate years 1\u20136) at a single institution participated in a perforator dissection session utilizing the simulation model. Each resident completed pre- and postactivity surveys to assess interval change in confidence in operating. The postactivity survey also asked residents to answer questions regarding their perception of the model's anatomic and surgical realism and utility in microsurgical training.<\/jats:p><jats:p>\n          Results\u2003Following a practice session using the latex-perfused, nonliving porcine abdomen, resident confidence was significantly increased in performing all key operative steps and the procedure overall (p\u2009=\u20090.001). All residents (n\u2009=\u200917, 100%) believed the model would improve \u201ctrainees' ability to perform perforator dissection in the operating room.\u201d Perforator, fascial, and pedicle anatomy were reported to be \u201cVery\u201d similar to human anatomy, with a median Likert score (MLS) of 4. Additionally, six out of the eight surgical steps were noted to be \u201cVery\u201d realistic, with only \u201cFlap Design\u201d and \u201cFascial Closure\u201d found to be \u201cModerately\u201d realistic with an MLS of 3.<\/jats:p><jats:p>\n          Conclusion\u2003The latex-infused porcine abdominal model is a novel, realistic simulation for microsurgical trainee perforator dissection practice. This model offers a suitable substitute for perforator dissection practice, as its implementation within a microsurgery training course improves resident comfort and confidence.<\/jats:p>","DOI":"10.1055\/s-0044-1779719","type":"journal-article","created":{"date-parts":[[2024,2,23]],"date-time":"2024-02-23T23:54:27Z","timestamp":1708732467000},"page":"571-577","source":"Crossref","is-referenced-by-count":2,"title":["Perforator
