A skin graft is a free skin graft, where a thin piece of skin is removed from a healthy area of the body. A free skin graft is a thin piece of skin taken from a healthy part of the body to cover the scar by removing the existing scar. Free skin grafting is suitable for people with large skin lesions or scars. It is important to note that patients with infectious diseases, blood diseases, and lung diseases are not allowed to undergo the procedure. As the free skin graft is made from your own skin tissue, there is less chance of rejection and the procedure is more effective. The free skin graft may damage the capillaries during the removal of the skin, which may result in localized hematomas, leading to necrosis of the grafted skin. If the graft is not secured properly, it may show signs of movement and may become necrotic due to lack of nutrients. After free skin grafting, you need to take good care of the wound and avoid squeezing the wound to avoid affecting the recovery. Nutritional supplements are also needed, with a diet high in protein and vitamin-rich foods. If you want to know what kind of skin graft is taken from your own skin, you can go to the regular hospital to consult about it.
