Hypertrophic scarring is a common postoperative skin issue, and various treatment options are available. Mild cases can be managed with medications such as anti-scar agents like tranilast capsules, which help suppress scar formation. For moderate hypertrophy, physical therapies—including pressure therapy, cryotherapy, and laser therapy—are effective choices. Pressure therapy involves using elastic bandages to apply compression, reducing scar development. Cryotherapy uses liquid nitrogen to destroy local cells, leading to necrosis and shedding of the scar tissue. Laser therapy employs specific wavelengths to reduce scar size and fade redness. In severe cases where scarring significantly affects appearance or skin function, surgical intervention—such as scar excision and re-suturing—may be considered. However, surgery carries risks such as infection and hematoma, so it should be performed at a reputable medical facility by an experienced physician. Additionally, proper postoperative care and avoiding direct sun exposure are crucial measures in preventing scar hypertrophy.
