Oil scalded scars can not be completely removed, but the appearance can be improved through standardized treatment, such as drugs, laser, surgical treatment and other methods. 1. Drugs: you can apply ointment to prevent scar formation, such as silicone gel, allantoin gel, etc.; if there is obvious scar hyperplasia, you can locally inject fluorouracil, tretinoin and other drugs to soften the scar tissue. 2. Laser treatment: laser treatment methods for colonoscopy include fractional laser, dye laser, etc. This method can soften the scar, stimulate collagen regeneration and rearrangement, and improve the appearance of the scar. 3. Surgery: If the scar affects the appearance or function and there is no obvious effect of conservative treatment, the scar can be surgically excised and then cosmetically sutured again, followed by local radiotherapy. The specific conditions and stages of scarring are different, and the treatment methods are different. It is recommended that patients who are willing to be treated go to regular hospitals for consultation and standardized treatment under the guidance of specialists. All of the above drugs should be used in accordance with medical advice.
