The scars left behind after skin wounds, burns, ulcers, etc., are called scars. Some scars remain deep on the skin and are difficult to remove. This also adds a scar to people's hearts. Scar repair surgery can remove scars. Common scar surgery includes skin grafting, grinding to remove scars, excision and suture, and skin dilator. Different scars require different surgical methods.

　　 1. Skin graft transplantation

　　 This method is mostly used in the treatment of scars formed by burns and scalds. It is a surgical method of transplanting healthy skin from the thigh, scalp and other parts to the damaged part. The disadvantage is that new scars will appear on the skin graft site due to the growth of hair on the transplanted skin, and the skin donor site will also have scars due to skin removal, and the recovery period is long, which requires a certain cost.

　　2. skin dilator

　　The method of skin dilator to remove scars is mostly used in burn scars. The method of operation is to embed several dilators in the surrounding skin of the damaged part to cover the affected part by expanding the skin. This surgical method of skin dilator scar removal also has many shortcomings. The patient may experience local swelling and pain and nausea, the neighboring organs may be affected, and the operation will have certain pain, accompanied by hematoma, skin blood flow disorder, and dilator fluid leakage. . Healthy skin will also become thinner due to expansion. This operation is more painful, long treatment time, and expensive.

　　 3. Resection and suture

　　Using the surgical method, the smaller scar is removed, and then sutured again. The possible problem is that skin bumps may appear after re-suturing the excision site, which may also cause organ asymmetry, which may cause new scars during surgery.

　　 4. Grind to remove scars

　　 Use medical electric sand office and other equipment to polish the skin of the scar area to make the skin smooth. If the operator does not operate properly, it may cause secondary damage to the scar. This method is mainly used for the treatment of hyperplastic scars and acne pits.
