After skin tissue injury caused by trauma and other factors, fibroblasts and capillary network proliferate to form new granulation tissue, which gradually stops the division of fibroblasts, resulting in imbalance and degradation of collagen fibers, nerve endings growing in, epithelial tissue at the edge of the wound growing towards the center, covering granulation tissue and forming scars.

Guiding opinions:

For scar plastic surgery, we should first find out the causes of scar formation, carefully examine and analyze the shape, nature and age of scar, and then make a treatment plan. For some relatively light scars, which are not too long ago, you can use dermabrasion to treat them. This method is much simpler and more convenient. Dermatization can treat superficial sunken and hidden scars left by smallpox, chickenpox and acne, and can remove pigmentation of flat scars.

For serious and stubborn scars, surgery is needed to remove and repair them. Scar plasty can be performed under local anesthesia or general anesthesia, and a large area of wound will form a hypertrophic scar because it loses more skin. Hypertrophic scars can lead to dyskinesia of muscles, joints and tendons. A serrated incision should be made during the operation to remove redundant scar tissue. Non-invasive micro-suture and tension-free suture are adopted to achieve the finest para-position growth. There is also a special scar plastic surgery, which requires excision and skin flap transplantation for a large area of stubborn scars. Skin grafting is to cover the wound with a piece of skin from other parts of the body. Sometimes it is necessary to transplant fat, nerves, blood vessels and muscles to the injured site. This technique should be used when a large area of skin is missing due to severe trauma. This skin grafting operation should first meet the functional requirements, and the second step should consider the aesthetic requirements.
