Skin and soft tissue expansion can be used. Skin and soft tissue expansion is a surgical method to use the expansion effect of tissue expander to obtain additional skin and soft tissue for skin defect repair and organ reconstruction.

Skin and soft tissue expansion is to bury a water bag made of silica gel in the skin around the scar, and then slowly expand to grow normal skin, thus growing redundant skin. Then, in the second stage, the scar skin is removed and the scar wound is covered with redundant skin to achieve the purpose of scar removal.
