Scar hyperplasia, also known as hyperplastic scarring, is considered to be related to personal constitution, local trauma and other factors, and can be treated with medication, surgery and physical therapy. 1. Drug treatment: glucocorticoid drugs such as prednisone can be used to improve the symptoms of localized scar hyperplasia through local injection. For linear hyperplastic scar caused by post-surgical trauma, injection of bleomycin hydrochloride can also be chosen. 2. Surgery: It is usually more suitable for patients who are not satisfied with the effect of conservative treatment for a long time, and can cooperate with the doctor to choose surgical excision. When the scar shrinks excessively, contracture will be caused, and scar contracture release can also be given to intervene. For larger linear proliferative scars, skin grafting or localized skin flap transplantation can also be used. 3. Physical therapy: According to the condition of hyperplastic scar, you can cooperate with doctors to choose laser therapy, pressure therapy, cryotherapy, radiation therapy, micro-needle therapy and so on to improve the local symptoms. There are many ways to treat hyperplastic scar, so you need to consult the doctor in time and have standardized treatment under the doctor’s guidance.
