Scarring is a relatively common benign proliferative clinical condition that has received widespread attention in recent years, with a low cure rate and a high recurrence rate. Scarring is an overgrowth of abnormal scar tissue that forms after a skin wound or healing. It often presents with large deposits of collagen fibers and stromal components and new capillaries in the dermis, and infiltrates into the surrounding normal skin tissue. In recent years, there has been an increase in the number of patients with scars, mostly adolescents or young women, on the head, face, chest, abdomen, back, and extremities, which not only impairs skin function but also affects aesthetics. Scars are usually treated by surgical excision, drug injection, radiotherapy or cryosurgery. Based on clinical experience, it has been found that the effectiveness of a single treatment for scars is limited and prone to recurrence. Therefore, in clinical practice, a combination of multiple treatments is generally used to treat scars. Not only is the treatment effect ideal, greatly improving the cure rate, but also effectively controlling the recurrence rate. The so-called combined treatment refers to the joint application of different treatment methods and drugs throughout the treatment process to achieve the best treatment effect. In the treatment of scars, super reduction fine suture technique is used after excision of the lesion, and the subsequent radiotherapy treatment is combined with attention to controlling the irradiation dose as well as adjusting the appropriate irradiation range, which will not produce any effect on the human body and effectively control recurrence with high patient satisfaction. In summary, the treatment of scars with surgical excision of the lesion followed by radiotherapy treatment is effective and safe, and is worth promoting. We remind our patients that they must find a professional doctor in a regular institution to operate the treatment in order to obtain a good treatment effect.
