Scar widening is generally caused by the proliferation of scar tissue, which can be treated by topical medications and local injections under the guidance of specialists, and serious patients can be improved by combined surgical treatments. 1. Topical medication: topical medication is usually silicone preparation. 2. Local injection treatment: local injections are usually glucocorticoid injections, such as Triamcinolone acetonide injection. 3. Surgical excision: If the scar site permits, part of the scar can also be excised through surgical means, and combined with local radiation therapy to prevent keloid scarring from reoccurring in the incision after surgery. Laser therapy and ultrasound can also be used to improve the scar. When the patient’s scar becomes wider, it is recommended to go to a regular hospital for timely examination and symptomatic treatment under the guidance of a professional doctor.
