First, contracture scars Contracture scars are scars that are named after the dysfunction they cause, and there are also obvious changes in appearance. It is mostly seen in the healing of deep burns, skin avulsion injuries, extensive subcutaneous cellular inflammation and other causes of limb extensive skin, subcutaneous tissue necrosis disease. Contracture scars are deep, thick and extensive, and often lead to changes in appearance and dysfunction due to contraction of the scar. If the contracture scar is not treated in time, it is likely to cause secondary contracture deformities in the deeper tissues. Due to the contracture of the scar and the lack of movement of the limb, especially near the elbow joint, heterotopic ossification will easily occur, further aggravating the functional disorders of the limb. Therefore, contracture scar should be treated at an early stage. Second, the treatment of contracture scars (a) laser treatment For the treatment of contracture scars, you can generally use the laser to soften the connective tissue of scars, along with the injection of drugs, so that the scar metabolism, degradation, color fading, and ultimately make the scars flat and smooth, and the color of the scars is close to the normal skin. This method can effectively treat the scar contracture caused by lip ectropion, eyelid ectropion, limb movement impaired scar symptoms, to reduce the pain of patients. （Surgery is still the main treatment for contracture scars compared to laser and medication. In the operation, the scar and normal tissues are gradually peeled off in layers through an incision perpendicular to the longitudinal axis of the contracture, and the wound surface is enlarged until the contracture is completely lifted. The surgical approach is suitable for the scar to fully enter the stabilization stage and step into the maturity stage. Finally, with the super-decreasing fine suture, the postoperative recovery effect is good, which greatly improves the appearance of the affected area, and the patient satisfaction is generally high.
