Li Chongjin, Department of Burn and Plastic Surgery, Mianyang People's Hospital: Wearing elastic sleeves will not affect children's development. Prevention and treatment of scar hyperplasia after burn is the most common problem in burn surgery, and it is also a headache for doctors and patients. Fibrous scar hyperplasia is an urgent problem to be solved in the burn world. Excessive scar hyperplasia can lead to joint stiffness, loss of motor function, limited activity, ugly appearance and so on. If there is no effective and thorough treatment for the scars that have been formed, there will be no effective and thorough prevention and treatment. In general, after skin grafting, fresh wounds gradually heal, and fibrous scar tissue begins to grow. At this time, the doctor will ask the patient to wear a medical rehabilitation elastic sleeve with appropriate pressure, good air permeability, softness and comfort, so as to restrain the excessive rapid growth of fibrous tissue to the maximum extent and keep the newly healed wound smooth. According to the area of the wound and the degree of hyperplasia of the patient, it takes more than 6 months or even several years to wear the medical rehabilitation elastic sleeve.
