The treatment of keloid is mainly based on surgical treatment, together with radiotherapy, silicone membrane covering and glucocorticoid injection treatment for comprehensive treatment. Surgical treatment is usually based on the area and thickness of the keloid, choosing single total excision, split excision, or flap transfer treatment after excision. Single total excision is to excise the lesion tissue completely, suture the deep tissue, try to keep the suture tension-free, so that it will be naturally aligned; while for larger lesions, it is also possible to expand the flap in one stage, and carry out keloid excision and flap transplantation in two stages. Radiotherapy can be received within 48 hours after surgery to enhance the therapeutic effect; silicone membrane can be used as early as possible after surgery to cover the keloid and inhibit keloid hyperplasia; for those who have a tendency to recur after surgery, glucocorticoid can be applied as early as possible to do intra-keloid injection therapy. It is recommended that patients with keloid scars on the chest go to the dermatology department or plastic surgery department of regular hospitals in time, and make individualized diagnosis and treatment plan and standardized treatment under the guidance of doctors.
