How to choose the time for surgical treatment of keloid scars? The maturity stage is the best time for surgical treatment of keloid scars caused by trauma and surgery, if surgical treatment is required, in the absence of dysfunction. This is usually after six months or one year after surgery or trauma, when the scar softens and basically matures and no longer changes. Surgery is contraindicated for hyperplastic and contractural scars during their proliferative and contractural phases. In the proliferation and contracture decompensation period should be cautious, it is best to avoid surgery. Of course, the first point of the choice of the timing of the surgery is that it should be carried out under the condition of basic health, which is the most important. In addition, for children’s scar surgery, it should be noted that if it does not affect the function and physical health, surgery is generally recommended to be carried out in preschool (5-6 years old), this is because, firstly, the child is not yet enrolled in school at this time, there is plenty of time for treatment, and will not be ridiculed by their classmates; secondly, children at this age can be better with the local anesthesia under the treatment, and the surgical risk is low. If the child is too young for surgery, because of poor cooperation, the need for general anesthesia treatment, so a small operation will be upgraded to a medium-sized surgery, the risk of surgery will also rise. For the betterment of your child, please try to follow your doctor’s advice. Last but not least, it is important to remind you that although surgical treatment can only be carried out when the scar reaches the mature stage, non-surgical treatment (photoelectricity, drug closure, etc.) can be started as early as 2-4 weeks after the injury, and for unstable scar, the earlier the non-surgical treatment is received, the better the result. Therefore, in addition to the timing of surgical treatment, it is also important to seize the best opportunity for early prevention of scarring.
