An Innovative Skin Simulation Model to Augment Competency-based Training in Facial Plastic Surgery

Area of Science:

• Biomedical Engineering
• Surgical Education

Background:

• Competency-based medical education (CBME) emphasizes learner-centeredness and accountability in medical training.
• Traditional surgical training models like "see one, do one, teach one" are being supplemented by simulation-based approaches.
• Improving surgical competencies requires innovative and accessible training tools for trainees.

Purpose of the Study:

• To evaluate a novel skin simulation model using hydrophilic barrier adhesive foam wound dressing.
• To assess its utility for plastic surgery residents learning cutaneous flap biomechanics and practice.
• To determine the effectiveness of this simulation model in enhancing surgical skills and confidence.

Main Methods:

• Utilized adhesive bilayer polyurethane foam island dressings, nearing expiry, as a skin simulation model.
• Conducted a simulation workshop for plastic surgery residents across different training years.
• Collected resident feedback on the model's texture, markability, and overall utility for flap and suture practice.

Main Results:

• Seventeen plastic surgery residents participated in the simulation workshop.
• The foam dressing model achieved 100% scores for flap and suture practice utility.
• High scores (88%-94%) were reported for texture, markability, and increased trainee confidence.

Conclusions:

• Adhesive bilayer polyurethane foam serves as an effective and novel simulation model for cutaneous skin flaps.
• This model aids in understanding skin flap biomechanics and practicing flap procedures.
• The simulation approach offers a valuable, accessible tool for plastic surgery resident training.
