Surgical incision hyperplasia is mostly considered to be caused by proliferative scarring, which can be treated with medication, physical therapy, surgery and other ways. 1. Drug treatment: patients with hyperplastic scar can take local injection of glucocorticosteroids, such as hydrocortisone, methylprednisolone, etc., or topical use of onion extract-containing preparations such as sodium heparin sodium allantoin gel and polysulfonic acid mucopolysaccharides cream, etc., under the guidance of doctors. 2. Physical therapy: some patients can also take pulse fuel laser, fractional laser, liquid nitrogen cryotherapy, radiotherapy, etc., so as to soften the raised scar and make it flat. 3. Surgery: If non-surgical treatments are ineffective, patients can undergo surgical excision, keloid contracture release, skin grafting, localized flap transplantation, etc. to improve the raised scar. Once diagnosed with hyperplastic scarring, patients should take relevant treatment measures according to their own needs and under the guidance of their doctors. During the treatment period, the skin should be clean and dry to avoid secondary infection.
