Scars generally refer to keloid scars, including conventional scar, hyperplastic scar, keloid, atrophic scar, etc. For the time being, there is no method to completely eliminate postoperative scar, which can be improved by medication as well as physical therapy and surgical treatment. 1. Conventional scarring: It is recommended that patients with conventional scarring after surgery should follow the doctor’s instructions to apply drugs such as sodium heparin sodium allantoin gel and silicone gel, which can improve the local scarring. 2. Proliferative scar: laser treatment helps to remove proliferative scar, such as dye laser, which is based on selective photothermal effect and releases high energy laser to facilitate the elimination of scar. 3. Keloid: For patients with keloid, surgical excision can be chosen to remove the keloid, after surgery with superficial radiation therapy to achieve the purpose of treatment. 4. Atrophic keloid scars: For patients with large atrophic keloid scars, filler treatments are needed, including hyaluronic acid filler and autologous fat filler, which can help to fill the depressed skin and achieve the effect of removing keloid scars. For patients who need to eliminate postoperative scarring, it is recommended to go to a regular hospital and choose the appropriate treatment under the guidance of the doctor.
