Scar constitution Scar constitution What is scar constitution Scar constitution Scar constitution The proportion of people with scar constitution in the crowd is very small, which is manifested through wound healing. The increasing surface scars not only affect the appearance, but also affect the functional movement due to local pain and red itching scar contraction. It is precisely because there are few people with scar constitution that some books also call people with keloids scar constitution. Keloid shows that after the wound heals, the scar grows outward, the skin surface is hard, and there may be a feeling of red pain, but it will not continue to expand after growing to a certain extent. There is a difference between scar constitution and keloid. After any part of the body is injured, people with scar constitution can have unlimited scar hyperplasia like keloids, while some parts of normal people will also have keloids, or scar healing caused by some reasons. In other words, keloids are an inevitable manifestation of scar constitution, and people with keloids do not necessarily belong to people with scar constitution. This kind of person after the wound heals. The increasing scar on the surface not only affects the appearance, but also affects local pain, redness and itching, and scar contraction also affects functional movement. People with scar constitution are prone to form hypertrophic scars or keloids with obvious symptoms after surgery, burns and trauma. At present, medical science can only diagnose the scar constitution according to the individual's performance, and can't really detect whether a person is a scar constitution by which detection index. In fact, there are very few people with real scar constitution. The diagnosis of scar constitution should be judged, and the treatment should be very cautious. Sometimes after treatment, the loss outweighs the gain. Keloid is pale red at first, and gradually protrudes on the skin surface, beyond the original damage range, forming a hard and elastic mass. After a few months, the color of scar plaque becomes pale, the surface is smooth and shiny, there is no hair, dilated capillaries can be seen, and there is itching, tingling or burning sensation, and some will rupture and bleed. Keloid is closely related to heredity, and people with obvious scars are sometimes related to allergic constitution. It is easy to happen to people with pigmented skin. People who are prone to acne, dull and dry skin, oily skin and sweaty skin are prone to acne. It is easy to have poor venous lymphatic reflux. Chest keloids are common in people with well-developed breasts. Hypertrophic scar is closely related to the degree of injury, as well as physical fitness, age, location and other factors. Thin and fat, especially developing women. This is due to the excessive proliferation of fibroblasts in these people during wound healing. Hypertrophic scar has no specific location. Generally, patients with hypertrophic scars and keloids can be judged as cicatricial constitution; Generally speaking, it is a scar that protrudes from the skin after trauma and is larger than the wound area. It is not that scar constitution can't do any surgery, but it is generally not suitable for cosmetic surgery and fine surgery, such as excimer laser surgery. Although the microstructure names of skin and cornea are different, the genetic control of scar constitution is the same. For example, even if a little extra tissue grows after laser surgery, it will have a serious impact on vision, so it is still listed as a surgical taboo. Scar 100% is related to human physique. Under normal circumstances, plastic surgeons consider whether surgery, burn (heat) injury and trauma are easy to form hypertrophic scars or keloids with obvious symptoms according to the following points. 1, whether there is a history of hypertrophic scar, keloid or old scar with proliferative period exceeding 1 year. 2. Is it allergic? 3. Whether there are 1 and 2 cases at home. The shape and classification of scars are different. Many terms such as idiopathic keloid, true keloid, pseudokeloid, keloid, hypertrophic keloid and keloid are used clinically, but there is no clear classification at present. People with acne-prone face and body, dull and dry skin, oily skin and sweaty skin are prone to scar. In addition, it is easy to have poor venous lymphatic reflux. Chest keloids are common in people with well-developed breasts. In addition, the upper and lateral sides of the upper arm (deltoid muscle), chest and scapula are the most common parts of keloids, and behind the ear, auricle, neck, occipital bone and upper pubic bone are also more likely to occur. On the contrary, keloids are not easy to appear in denervated areas (furuncle) and spinal paralysis areas. Treatment 1, scar excision and suture: it is a common plastic surgery method in scar treatment and can be used for small scars. 2. Skin grinding: it is a surgical method to improve the irregular part of skin surface by grinding epidermis and dermal papillae, making it smooth and similar in color. Suitable for acne, smallpox, chickenpox, herpes zoster, eczema, trauma, burns or superficial scars left after surgery. If necessary, scar treatment can be performed at the same time as surgical resection, and the effect is better than simple grinding. 3. Scar release and local plastic surgery: For smaller tension cord-like and reticular scars, the scars can be removed, and then the normal skin tissue around them can be used to form a flap, and the skin defects in the scar area can be repaired by cross-shifting. 4. Scar excision and free skin grafting: Large hypertrophic scars can be removed by plastic surgery, and then free skin flaps from normal parts of the body can be transplanted to the scar wound to repair the wound and restore skin function. No matter what kind of scar dressing is used, it is very important to follow the doctor's advice after scar treatment. And the nursing work after scar surgery.
