Introduction The majority of people are introduced to wound closure by attempts to suture pieces of green towel or foam and then move onto the real thing. An attempt has been made to produce a skin substitute which has some of its characteristics, giving a greater feel of tissuehandling and allowing a wider range of minor surgical techniques to be performed. It is also extremely easy and cheap to produce and is an ideal introduction for nursing and medical staff alike.
Creating defects on the model hasa similar feel to that of cutting skin and when an ellipse is excised a wedge of gel is easy to take with the foam due to their adherence (see Figure 3). Most types of skin closure can be practised such as adhesive strips, tissue glue and various suturing techniques including subcuticular closure (Figure 3).
Construction The model has both skin and underlying soft tissue components the bond between the two being the key to its success. Figtire I shows the materials required, namely a roll of surgical foam dressing, two plastic containers (denture pots are ideal) and gelatine or commercially available dessertjelly. The foam is stuck onto the pot, the bottom removed and the liquid gel added (Figtrre2). The correct consistency of the gel is obtained by placing the cubesin a

Subcutaneouslesions can also be simulated by sticking objects suchasdried pulsesto the foam prior to adding the gel. These can be palpated and then excised and closed (Figure 4).
Conclusion The skin model can be made easily and cheaply to provide a safe and realistic introduction into skin and soft tissue handling for those who are about to embark on the real thing.
