Treatment of sebaceous cysts is based on surgery, which involves making incisions on the surface of the body and the possibility of scarring after surgery. Surgery for sebaceous cysts in normal state can be chosen from plastic surgery and the scars will not be too obvious, while in some patients with better skin conditions, the scars will be almost invisible. The advantages include: 1. fine surgical operation; 2. fine sutures used in the operation; 3. plastic and cosmetic sutures can be taken for incision closure; 4. anti-scar growth treatment after the operation. If the sebaceous cyst is complicated by infection and forms an abscess, the surgery in this case is not simply to remove the cyst, but to incise and drain the abscess. After the abscess is cut and drained, the local scar will be bigger and more obvious after the change of medicine to promote healing, which is completely different from the normal sebaceous cyst surgical excision scar.
