One of the things that patients must be informed of before every surgery is the possibility of incisional scarring after surgery. Many patients are deterred from having surgery because of the fear of scarring, especially for head and face surgery. What is understood by postoperative incisional scarring is the possibility of scarring after surgery. So what is the meaning of “scar” and “scar”? The first point is that the definition of scarring dictates that any surgery will leave a scar. The Oxford Dictionary defines a scar as a mark left on the skin after a wound or burn has healed. This statement tells us that the way injured skin heals is and can only be scarred, and that scarring is the inevitable result of trauma. As long as you have a skin injury or surgical incision the skin is bound to scar, there is no need to doubt that. Next, some patients will ask: so why is it that some people do not have scars after surgery (meaning that the naked eye can not see the scar), you say this is not against the facts? This is the second point I am going to make. The second point is that there is no scar that can be seen after the surgery, and skin trauma is bound to produce scarring is not contradictory. Patients and friends understand that the scar is an image of the concept, specifically, the scar should be depicted as leaving an irregular protrusion on the surface, hard, or may be accompanied by pain, redness, itching does not have the normal structure of the skin tissue and physiological functions, the loss of normal tissue vitality, abnormal, dysfunctional tissue. In other words, the patient understands that the scar is destroyed the beauty of the body surface, then did not destroy the beauty of the body surface is also understood as no scar. But the fact is that scarring continues to accompany the healing of trauma, which is not subject to our will, but the color of the scar can be normal skin color, whereas there is either deepening of pigmentation or hypopigmentation. So those well healed keloid scars of normal skin color are perceived visually as not disrupting the beauty of the body surface and are treated as if no scars have been produced. This type of wound healing is what our surgeons are looking for and can be achieved through effective hypotony, precise alignment, and non-invasive suturing techniques. It is also important to note that unlike the skin, the scar has no skin texture and no skin appendages. After the above explanation, I think all patients and friends understand that keloid and scar are actually the same thing, a concept. Whether or not to leave a scar after surgery, this is the patient’s pursuit of beauty, but scarring is inevitable, for us operators do is to do everything possible, with all means, is our patients postoperative incision scarring minimization or no scar. The above two points understand, I have achieved the purpose of writing this article popularization, the following is about scarring, scarring and scar classification as a common sense knowledge listed for all patients and friends to understand There is a kind of skin is very easy to leave scars, medical books call this skin for scarring. Scars are a very small proportion of people in the population, scarring is the human skin tissue by the outside world after various traumatic injuries, wound healing place of the skin Vicryl connective tissue proliferation, and the formation of hard, irregularly shaped lumps, and often accompanied by scars, itching, pain, and other clinical symptoms, which manifests itself in the healing of wounds, the surface of the scars is a persistent increase, not only affecting the appearance, but also the local pain, red itch! Scar contraction also affects functional movement. Some books will grow scars of people also known as scarring, scarring manifested as wound healing scars grow outward, protruding from the skin surface, hard, there can also be red pain, but the growth to a certain extent, no longer continue to expand. There is a difference between scarring and scarring. Scarring can occur as an infinite proliferation of scar-like scars in any part of the body of the scarred person after injury, while scarring can occur in certain parts of the normal population or due to certain reasons for the healing of scars. In other words, scarring is an inevitable manifestation of scarring, and those who have scarring do not necessarily belong to the scarring population. Classification of scars: First, from the scar tissue pathology classification: 1, normal skin scars 2, proliferative scars 3, scars Second, from the clinical manifestations and histological changes classification 1, superficial scars or flat scars 2, cord-like scars or contracture scars 3, webbed scars 4, depressed scars 5, atrophic scars 6, bridging scars and redundant scars 7, hyperplastic scars 8, scars 9, scars cancer Scar Cancer.
