A raised hyperplastic scar is usually a scar that is in a state of hyperplasia and is the result of over-repair of fibrous tissue after trauma to the body. It can be relieved by physical therapy, surgery and medication. 1. Physical therapy: including cryotherapy, laser therapy and pressure therapy. Smaller scars can be treated with liquid nitrogen cryotherapy, linear scars can be eradicated with laser therapy, and large scars can be treated with pressure therapy. 2. Surgery: mainly includes skin grafting or local flap transplantation, keloid contracture release and other modalities, which is suitable for the ineffective conservative treatment for a long period of time or severe linear scars. 3. Pharmacological treatment: Bleomycin or mitomycin C, 5-fluorouracil, silicone preparations and other drugs can be used in the treatment of proliferative scarring. If proliferative scarring occurs, you should go to the hospital in time to improve the relevant examination, symptomatic treatment under the guidance of the doctor, and avoid unauthorized use of medication.
