If the burn site is the whole chest and neck, even skin grafting may cause scar contracture, which will affect the function and appearance of the neck. If the neck does not exist, the scar contracture of the chest may also cause the deformation of the chest, affecting the respiratory function and appearance. Pay attention to functional training after skin grafting. With proper training, the adverse effects of scar contracture can be reduced. If you find that your child's scar continues to grow or contracture increases within six months after skin grafting.
