Novel method for training skin flap surgery: Polyurethane foam dressing used as a skin equivalent

Research output: Contribution to journalArticle


BACKGROUND. With a substantial rise in the incidence of skin cancer, skin surgery has become an increasingly large part of dermatology. Skin surgery is best performed by dermatologists. This demands effective training in dermatologic surgery, including flap surgery. OBJECTIVE. To find a modern alternative to traditional training on pig's feet skin in teaching flap surgery to residents in dermatology. MATERIALS AND METHODS. A face with expression lines printed on a nonadhesive hydrocellular polyurethane dressing (Allevyn, #66007638, 20 x 20 cm, Smith & Nephew Medical Limited, Hull, England). Tumors were marked in suitable locations,necessitating the use of transposition, advancement, and rotation flaps. Twenty-two residents were trained in flap construction, excision, and closure. RESULTS. Training on Allevyn was rated high by participants. CONCLUSION. Allevyn has unlimited storing qualities and skinlike qualities when incised, extended, and sutured. Sutures stay tight without the help of an assistant. Training on Allevyn gives students a good understanding of the mechanics of skin flaps, including transposition, advancement, and rotational flaps. The Allevyn is kept by the student after the course and can be studied afterward. Skin surgery training on Allevyn is superior to traditional training in pig's feet skin.
