Three-Dimensional Simulation of Scalp Soft Tissue Expansion Using Finite Element Method

Abstract EN

Scalp soft tissue expansion is one of the key medical techniques to generate new skin tissue for correcting various abnormalities and defects of skin in plastic surgery.

Therefore, it is very important to work out the appropriate approach to evaluate the increase of expanded scalp area and to predict the shape, size, number, and placement of the expander.

A novel method using finite element model is proposed to solve large deformation of scalp expansion in this paper.

And the procedure to implement the scalp tissue expansion with finite element method is also described in detail.

The three-dimensional simulation results show that the proposed method is effective, and the analysis of simulation experiment shows that the volume and area of the expansion scalp can be accurately calculated and the quantity, location, and size of the expander can also be predicted successfully with the proposed model.
