Scar hyperplasia occurs most often after healing of deep burn wounds, and also commonly after traumatic skin grafting, with reticulated, value-added scars around the sutures of the skin fragments. The most common is incisional scarring after suturing of any incision. Augmentation scars appear as protruding surfaces with an irregular shape, uneven height, and do not extend beyond the original wound. It is red and bleeding, solid and tough, often painful and itchy The proliferative phase of the scar usually lasts for 6 months, with a few extending to 1-2 years, or individually for several years. During this period, the scars are locally swollen and congested, gradually thickening and protruding from the surface, irregular in shape, red on the surface, and firm and tough. After the hyperplasia period, the scar will enter the decompression period of about 6 months to 1 year. During the receding period, the scar changes from active proliferation to receding, the height gradually decreases, the hardness also begins to soften, the color changes from red to purple, purple-brown, and pigmentation, the capillary dilation on the scar surface disappears, and the itchy and painful symptoms are reduced. However, after the decreasing period, the scars can only fade mildly, after which the scars will enter the mature and stable period, and will not fade on their own without scar repair. So how to treat hyperplastic scars? The following options are generally adopted: 1. Surgical excision? Super tensioning fine suture? Laser combination therapy 2.Injection therapy? Fractional laser? Phototherapy 3.Surgical excision? Super reduction fine suture? Laser combination treatment 4.Keloid core excision? Scar skin replantation? Laser combination therapy
