Many scar patients call to ask: When is the best time to treat their scar? What is the best treatment option for you? Here are some brief answers to these questions. After early burns, the scar heals after repair, but there is also a scar degradation and remodeling process, during which the local inflammation gradually subsides, blood circulation is gradually and steadily established, the scar starts to soften, the color becomes lighter, and the pain and itchiness is reduced, generally speaking, this process takes about six months to a year for most people, with a longer recovery time for children and a shorter recovery time for the elderly. Unless the scar affects the local function (e.g., lid, lip, or small mouth deformity), surgery is not recommended during this period, so the timing of treatment is usually six months after the scar is stabilized. If there are serious scar complications that affect organ function, surgery is required earlier. The choice of treatment plan is closely related to the scar area and the degree of tissue loss. If the skin defect is not serious and can be accomplished by direct excision or local reshaping, the treatment time is usually about one week, and most of the surgery can be done under local anesthesia on an outpatient basis without hospitalization, with the exception of children. 2, for patients with more tissue defects, according to their own conditions, they can choose implants, free flaps, skin tubes, expansion flaps and other options, the implant method is simple, after removing the original scar, cut from other parts of the body should be the size of skin pieces, the treatment time is about half a month, the disadvantage is that the color of the transplanted skin and the surrounding is not coordinated, like a patch, and the donor area will leave a scar. Free flaps are cut from other parts of the body with a vascular tip fascial fat flap, and anastomosed with the vascular bundle near the scar area, which takes about half a month. The skin tube is generally suitable for patients with large facial scars and no good local skin, especially for nasal and lip defects, and the operation is usually performed in 3 stages for about 3 months. Expansion flap is to use subcutaneous implantation of expander for normal expansion around the scar, regular injection of water into the expander at intervals of 4-7 days each time, after the skin increment meets the requirements of the second phase to remove the expander, excise the scar, transfer the expansion flap to cover the defect wound, this method is suitable for patients with sufficient normal skin around the scar area for expansion, the long-term effect is the most beautiful, the disadvantage is that the treatment period is long about 6-8 months or so .
