Predicting the effect of aging and defect size on the stress profiles of skin from advancement, rotation and transposition flap surgeries

Predicting mechanical stress contours on skin resulting from local tissue rearrangement surgeries is needed to design optimal treatment plans and avoid wound healing complications. Finite element (FE) simulations of skin tissues have been shown to be …

Propagation of material behavior uncertainty in a nonlinear finite element model of reconstructive surgery

Excessive mechanical stress following surgery can lead to delayed healing, hypertrophic scars, and even skin necrosis. Measuring stress directly in the operating room over large skin areas is not feasible, and nonlinear finite element simulations …
