Weekly scar specialist clinic, always receive scar patients from all over the country, see a variety of different types of scars, some scars are always shocking …… Various causes of scar proliferation and itchy and painful, unbearable, causing unbearable pain to the patient, which prompted the plastic surgeon is constantly thinking: how to prevent scar proliferation at the This has prompted plastic surgeons to constantly think about: how to prevent scar proliferation at an early stage and how to effectively treat scars after proliferation? The skin layer of the body is subjected to various causes of damage to the formation of scars, scars are natural products of the healing process of trauma, moderate scar formation is a physiological and self-defense appearance, but excessive scar proliferation is a pathological change. There are many factors that can cause such pathological changes, such as: wound infection, excessive wound tension, external friction stimulation, hormone secretion abnormality and so on. Pathological scar proliferation includes two conditions: hyperplastic scars and scars. During normal wound healing, the balance between collagen synthesis and degradation is maintained, but in hyperplastic scar and keloid, this normal balance is disrupted, and collagen synthesis significantly exceeds degradation, which ultimately leads to a large accumulation of collagen. How to prevent scarring: 1, prevent wound infection If in the early scar healing process, redness, swelling, pain, blood seepage, pus and other symptoms, suggesting that the wound may be infected, the wound healing after the infection from (excellent healing) into a grade B healing (healing defects, the incision appeared inflammatory reaction, but did not pus) or grade C healing (incision pus after open drainage and change of medication to heal), resulting in a more obvious scars. . Therefore, preventing wound infection should be put in the first place to prevent scar proliferation. 2, avoid excessive wound tension Wound tension is one of the most important factors in the formation of scars, excessive tension on the one hand can stimulate scar proliferation, on the other hand can also make the scar wider. Therefore, plastic surgeons often use multi-layer suture “tension-reducing fine suture” when dealing with the incision, so as to reduce the wound tension and achieve the purpose of minimizing the scar. Nowadays, we have further improved the suture to “Super Tension Reducing Fine Suture”. Postoperatively, we use some drugs, tension-reducing devices or equipment, such as botulinum toxin injections, external skin tension reducer, tension-reducing tape, etc. to further reduce the tension of the incision. 3.Reduce external friction stimulation, proliferative scars or scars due to itching and scratching, or by the clothing constantly rubbing, friction stimulation will lead to more serious scars, and even lead to scar breakage and erosion, the formation of long-lasting ulcers and malignant transformation into skin cancer. Therefore, the use of some topical anti-itching drugs, wear some loose clothing, or external silicone scar paste to reduce the external friction stimulation. 4.Avoiding sunlight; after wound healing, the newborn skin is tender, and the ultraviolet radiation in sunlight stimulates melanocytes to secrete melanin, which is easy to form hyperpigmentation, so we should pay attention to sun protection. 5, early can not use cosmetics, skin care products, as well as soap coated wounds. Because all kinds of cosmetics and skin care products may contain lead, mercury, silver and other heavy metals and photosensitive substances, they will stimulate the skin pigmentation. 6, reasonable diet: 1) Reduce spicy stimulating foods (such as wine, chili peppers, raw garlic, ginger, mustard, etc.). Because spicy stimulating food will promote scar proliferation. 2) Eat less drugs containing lead, mercury, because it will promote hyperpigmentation. 3) Eat more vitamin-rich vegetables and fruits and some protein-rich food. 7, prohibit smoking: smoking will affect the wound healing, and then increase the scar. Research suggests that some substances in tobacco make tiny blood vessels spasm, hindering the exchange of oxygen between tissue cells, resulting in insufficient saturation of oxygen in the blood, which leads to tissue wounds difficult to heal. 8, reasonable regulation of hormone secretion: puberty and pregnancy due to the body’s metabolism as well as hormone secretion is more exuberant, to promote hyperplastic scars and the formation of scars. Research suggests that excessive secretion of estrogen, androgen, and thyroid hormones may play a role in the development of hyperplastic scars and keloids. 9, the comprehensive treatment of scars can be divided into surgical treatment and non-surgical treatment: 1) non-surgical treatment: pressure treatment, keloid topical medication, drug injection therapy, radiation therapy, laser therapy, scar abrasion. (2) Surgical treatment: after surgical excision of the scar, super reduction of tension fine suture and so on.
