Surgical scar removal methods include skin resurfacing, keloidectomy suturing and keloidectomy free skin grafting. 1. Skin resurfacing: It is suitable for small superficial scars and hyperplastic scars, etc. Through resurfacing, the surface of the skin will be changed and the collagen fibers and elastic fibers of the dermis will be rearranged, so as to achieve the effect of improving the appearance of the scar. 2. Scar excision suture: It is mainly applied to limited scar, keloid and severe hyperplastic scar. Keloidectomy suture is a surgical way to remove localized scar tissue, and then again reduce the tension, cosmetic surgery suture, so that the more obvious scar is transformed into a smaller scar. 3. Keloidectomy free skin grafting: Surgical excision of large hyperplastic scar on the body surface, and then take the normal free skin from hidden parts of the body, and transplant it to the scar wound to close the wound. However, this usually does not significantly improve the appearance and is mostly used in cases where the scarring causes dysfunction. Patients who are willing to have scar treatment should go to a regular hospital and choose the appropriate surgical method for treatment under the guidance of a specialist.
