Scar (scar) is a collective name for the appearance and histopathological changes of normal skin tissues caused by various traumas, and it is an inevitable product of human trauma repair process. When the growth of scar exceeds a certain limit, various complications will occur, such as the destruction of appearance and functional activity disorders, which bring great physical and mental pain to patients, especially the scar left after burns, scalds and severe trauma. When the body suffers from accidental trauma, surgical suturing is a common coping method that promotes muscle healing and plays an important role in the rescue of trauma, but also plays a decisive role in the shape of later wound healing, that is, scarring. So, what is scarring? Scarring is characterized by a persistent increase in surface scars after wound healing, which not only affects the appearance, but also local pain, redness and itchiness scar contraction also affects functional movement. People with scars are also known as scarred people. Scars grow outward after wound healing, protruding from the skin surface, hard, and can also have red and painful sensations, but after growing to a certain extent, they no longer continue to expand. Patients with hyperplastic scars and scars are generally considered to have scarring; in layman’s terms, they are scars that protrude from the skin surface and are larger than the wound area after trauma. The surgical scars left after stitches are either flat and depressed or “centipede-like” hyperplastic scars, which not only affect the appearance, but are also accompanied by the risk of breakage and subcutaneous nodules, which are more dangerous to health, so how to get rid of hyperplastic surgical scars? How does the ugly “centipede scar” form? The “centipede scars” that scar patients suffer from are actually caused by excessive skin tension around the scars. The greater the tension of the skin on both sides of the suture, the less easily the wound will close, and the body will receive the signal of “needing more tissue”, and more scar tissue cells will grow to close the wound, resulting in a “centipede scar” after a longer period of time. Hyperplastic surgical scars should not be ignored It has long been thought that stitch scars are harmful to patients because they affect aesthetics, which is a common cosmetic problem that patients request treatment for. However, clinical data shows that in addition to affecting aesthetics and being discriminated against, the greater harm of stitch scars is the appearance of hyperplasia, rupture and bleeding, ulceration, subcutaneous nodules, causing infection, etc. In serious cases, they can cause skin lesions, such as pimple tumors, or even cancer, making scar patients suffer greatly. Common treatment methods for hyperplastic surgical scars 1.scar patch The scar patch mainly plays a preventive role for scars through the role of pressure and wound moisturizing, and can play a good auxiliary role in the treatment of scars. 2.Closure needle Closure needle is injecting hormonal drugs into the scar by external injection, which makes the capillaries inside the scar closed and necrotic, and reduces the nutrient supply of the scar, thus inhibiting the scar. Multiple injections are usually required. 3.Abrasion Abrasion needs to be performed several times to see the effect. It is important to have enough patience during the treatment. 4.Fractional laser Laser treatment is mainly used to improve the symptoms of mild scars by grinding scar tissue layer by layer through superficial photothermal stimulation. 5.Surgical excision The most contraindicated blind surgical excision for hyperplastic scars (scar body) is that ordinary surgical excision can only remove the surface part and cannot effectively control the root cause of scar proliferation, which will easily cause scar recurrence after surgery. Scar surgery requires scar excision followed by reduction of fine sutures is an increasingly sophisticated surgical method commonly used in the treatment of scars and is mostly applied to small scars. By fully reducing the tension of the incision and fine operation during the surgery, secondary injury is reduced and the degree of postoperative scar growth is minimized. Again, this kind of excision requires professional anti-scar treatment, not ordinary excision. Warm reminder: Although the above methods can treat scars to a certain extent, the final choice of which one to treat scars requires the patient to visit the hospital and determine whether it is a single method or a comprehensive way to treat scars according to the patient’s own scar situation.
