Scarring is an inevitable result of deep trauma healing. Scars located in exposed areas and abnormally proliferated scars often affect the patient’s appearance, cause dysfunction, and even undergo malignant changes and develop into scar cancer. Therefore, the prevention and treatment of scar has become an important research topic in plastic surgery. Scar prevention and treatment methods are categorized into surgical, non-surgical and combined surgical and non-surgical therapies. Currently, there is no effective method that can be applied to all types of keloid scars. We propose a dynamic therapy for scar prevention and treatment, aiming to provide a new strategy for clinical scar prevention and treatment, and to achieve the best results in scar prevention and treatment. The guiding principle is to combine prevention and treatment, and to integrate preventive measures into treatment. The main methods are as follows: one is to promote the early healing of wounds, and actively take effective methods to promote wound healing after trauma; two is to actively take preventive measures after wound healing, and one month to 1~2 years after wound healing is an important period to prevent scar proliferation; three is to stabilize and mature scar proliferation and use different methods of treatment according to different situations; four is to carry out dynamic treatment according to the above methods, and the cycle is repeated until satisfactory results are achieved. Until satisfactory results are obtained, the dual purpose of treatment and beauty is achieved at the same time. Commonly used non-surgical treatments include radiation, medication, compression and physical therapy. Commonly used surgical treatments include keloidectomy and suture, skin adhesive bonding, skin grafting, skin flap grafting, abrasion, and skin soft tissue expansion. The combined application of the above methods can achieve good therapeutic results. Case 1: perioral hyperplastic scar Case 1: after keloidectomy and full-thickness skin grafting (2 weeks) Case 2: post-burn scar deformity of both hands Case 2: after post-burn keloidectomy of both hands and tomographic autologous skin grafting (3 weeks) Case 2: after post-burn keloidectomy of both hands and tomographic autologous skin grafting (3 weeks), both hands had good function of making a fist.
