**7. Mode of use**

For practical purposes, a working model of bond paper can be made to evaluate the different possibilities according to the anatomy and the particular conditions of the skin surrounding the lesion. The working models included here can be enlarged or reduced in size by using a regular copying machine, in advance of the operation. They could be used on the spot to test the more convenient position according to the size of the lesion to be removed. The center portion of the selected model can be removed in order to estimate the resection margins and the proper orientation of the incision.

**9. Conclusion**

In this article, I am presenting a variety of working models for closure of skin defects of different shapes along with their corresponding indications and mode of use. These working models can be enlarged or reduced in size using a regular copying machine in order to evaluate the best possibilities related to the position of the incision. The great advantage of this method is that the geometrical results are always predictable. Furthermore, this method will improve the survival of the flaps and the cosmetic results.

*The oval incision can be used for skin lesions of similar shape, for instance for two continuous round lesions. This incision would be very useful when removing large skin lesions of similar shape because the wastage of* 

In summary, the surgeon can use a variety of skin incisions taking advantage of the minimal tension lines of the skin and also taking into consideration the

The **oval** and the **elongated hexagonal** (**Figures 10** and **11**) incisions are indicated when the skin lesions have a similar shape and when there is not enough room for extension of the incision at the ends. Besides this, the wastage of normal skin for
