The treatment methods for chest scarring include medication, liquid nitrogen cryotherapy and surgery. 1. Medication: The early stage of scar formation can be softened to a certain extent by topical medications such as silicone gel and cumquat ointment. You can also inject glucocorticoids such as trimethoprim injection into the scar tissue to treat it. 2. Liquid nitrogen cryotherapy: If the size of the chest keloid is not big, the local scar tissue can be removed by cryotherapy. It is also ideal for smaller keloid scars. 3. Surgery: If the above treatment is not effective, or if the keloid is accompanied by obvious pain, itching and other sensory abnormalities, surgery can be performed. Generally speaking, after the keloid is removed, the wound can be repaired through localized tension-reducing sutures, skin grafts and flaps. Because the surgery is invasive treatment, it is necessary to follow the doctor’s instructions to standardize the anti-scar treatment after the operation. Patients with keloid scars on the chest should go to regular hospitals to receive treatment and take targeted treatment measures under the guidance of specialists.
