Scalp scar surgery generally refers to the surgery to remove the scar on the scalp, including keloidectomy direct suture, keloidectomy Z-plasty, keloidectomy combined with skin grafting and so on. 1. Keloidectomy with direct suture: When the scar on the scalp is relatively small, it can be treated in this way by removing the scar and then suturing it after the reduction of the scar. 2. Keloidectomy Z-plasty: when the scar on the scalp is large and cannot be sutured directly after excision, it can be reduced through auxiliary incision to reduce local tissue tension and then sutured after decompression. The surgery cannot be performed when the body cannot tolerate it or when there are symptoms of local infection. 3. Scar excision combined with skin grafting: when the scar on the scalp is large and cannot be sutured by local flap transfer, the scar tissue can be excised and skin grafting can be done by taking the skin from the groin and thighs bilaterally. Patients who are willing to be treated are advised to go to the hospital in time and choose the appropriate treatment under the guidance of specialized physicians.
