Description of cutaneous excision and suture using a mathematical model

Mathematical models are being developed at a fast rate in industry thanks t o computer technology; they are used to simulate motion and deformation ove r time to test materials and objects in a virtual manner. These modeling te chniques are being developed in medicine, but they remain, at this time, in the domain of biomechanical research. We report a mathematical model for c utaneous excision and suture, which we have used to predict the deformation s and tensions that result when using four different forms of excision. The results are expressed in numerical and graphic form. The results obtained corresponded with our experience in dermatologic surgery. Uses and limits o f this model are discussed.
