For the phenomenon of postoperative keloid, which usually belongs to the manifestation of abnormal proliferation of connective tissues in the skin, we can cooperate with specialists to choose medication, physical therapy, surgical intervention and other methods of treatment. 1. Medication: patients can use Triamcinolone acetonide or compound betamethasone to be injected into the skin lesions, which can prevent the keloid from stretching outward, and gradually soften and shrink. 2. Physical therapy: For smaller scars, the doctor can usually try keloid cryotherapy, which is a physical cryotherapy technique to remove localized keloid scars. 3. Surgical intervention: For medium to large keloids that appear in critical areas, such as the ear, surgical excision, skin grafting and flap transplantation can be performed in conjunction with the doctor. Post-operative treatment with regular radiation therapy is generally recommended to avoid re-formation of keloids. It is recommended that patients with postoperative keloids should cooperate with their specialists in treating their condition and should not blindly use medication.
