Scars after removing the stitches can be improved by medication, physical therapy, and surgical treatment to achieve the purpose of permanent removal. 1. Medication: Silicone gel patch, silicone gel coating and other products can be used at the scar to inhibit scar proliferation. If the keloid scar has formed a raised lump, it can be locally closed and injected with Triamcinolone acetonide injection, which can make the local keloid scar tissue atrophy, thus making the hyperplastic scar gradually become softer and smaller. All of the above drugs should be used under the guidance of specialists. 2. Physical therapy: For the scar that is not well treated by medication, you can choose to use fractional laser and other photoelectric treatment methods to improve the appearance of the scar by rearranging the local scar tissue through the action of light and heat. It should be noted that new scars may appear if the laser is not operated properly. Therefore, you should choose regular hospitals for treatment. 3. Surgery: If the scar is large in size or the above treatments are not effective, it can be treated by direct excision, scar reshaping or local flap transfer under the guidance of specialized doctors. However, surgery has the risk of scar formation again, so be careful. Patients can eat more vitamin-rich fruits and vegetables and less spicy and greasy stimulating food. After the removal of stitches, patients who have the need to improve scarring should go to the plastic surgery department of a regular hospital in a timely manner, and under the guidance of a specialized doctor to carry out regular treatment.
