Scar recurrence after surgery can go to the hospital to use other treatments, such as compression therapy, laser therapy, cryotherapy, radiation therapy and so on. 1. Compression therapy: Compression therapy is the use of compression garments or bandages to prevent and minimize the formation of scars, usually started after surgery, and need to be maintained for a long time. 2. Laser therapy: Laser therapy includes pulsed dye laser and fractional laser, which can inhibit or reduce the blood supply or congestion of the keloid and inhibit keloid growth. 3. Cryotherapy: If the scar is not particularly large, you can try liquid nitrogen freezing; however, because cryotherapy is more traumatic, it may still cause keloid hyperplasia, so you need to choose carefully. 4. Radiation therapy: Radiation therapy mainly involves X-rays and electron beams, which can inhibit capillary proliferation at the incision site, reduce the release of inflammatory mediators, and play a role in treating keloid scars. The standardized treatment for keloid scars is surgical excision and postoperative radiation therapy. The specific condition of the keloid is different, the treatment method is different. Patients who wish to be treated are recommended to go to a regular medical institution for consultation and standardized treatment under the guidance of specialists, so as to avoid adverse consequences.
