Laser Dot mole wound cosmetology refers to the use of various minimally invasive techniques in the process of wound repair, in order to maximize the satisfactory cosmetic effect after operation. With the development of society and the improvement of people's living standards, people's expectations for the effect of plastic surgery, especially head and face plastic surgery, are constantly improving, which is a test for plastic surgeons. Only through strict formal training and mastering all kinds of minimally invasive techniques can we calmly cope with this challenge. Taking the operation of nevus as an example, thousands of patients with nevus are treated every year, with facial and neck nevus being the most common. They come in different sizes. Facial nevus can be treated by high-frequency beauty instrument or laser, and there are many surgical treatments, such as direct excision and cosmetic suture, fractional excision, skin expansion and flap transfer and repair. In other operations, large needle thick thread suture will leave obvious eye scar and suture scar on the skin, similar to "centipede foot" However, micro-needle thread for cosmetic suture, imported non-invasive suture thread for subcutaneous tissue suture and hair thread for skin suture can be absorbed. In the aspect of suture technology, the subcutaneous tissue is removed in a trapezoidal way, so that the tension during suture is mainly distributed in the subcutaneous layer, while the skin layer is healed without tension, and the scar after operation is small and flat. During the whole operation, we should strictly follow the exquisite and meticulous operation style, and if possible, we can perform the operation under a magnifying glass in order to exchange the least tissue trauma for the most satisfactory operation effect. Plastic surgeons must have a high aesthetic angle and master all kinds of minimally invasive techniques in order to achieve good cosmetic results. What is a mole? Will it become skin cancer? Nevus are benign tumors on the body surface. According to pathological classification, nevus can be divided into three types: (1) borderline nevus: located at the junction of epidermis and dermis. More common in palms, soles, lips and external genitalia. The surface is flat or slightly high, with the size of 1-2 mm, and it is light brown, brown-black or blue-black. There is the possibility of canceration, and melanoma can appear. (2) intradermal nevus: It exists in the dermis. The surface is smooth and the boundary is clear. More than 1mm, the growth is flaky, flat or slightly convex. The color is dark and uniform, with light brown, dark brown or dark black. Cancer does not usually occur. (3) mixed mole: It is a mixture of the above two, generally like intradermal nevus, and it can also become cancerous due to the composition of borderline nevus. Everyone has moles, but which moles are easy to become cancerous? What is the sign of the evolution from common nevus to melanoma cancer? If the mole suddenly increases in a short period of time, it will quickly form a raised nodule and the color will deepen, so be alert. The nevus keeps expanding outward, the boundary is blurred, and even pseudopodia appears. When it expands to a certain extent, papillary hyperplasia or rupture occurs, forming a small ulcer (often in the shape of a fire spout). The surface is easy to bleed, ooze or be covered with blood scabs, and black spots, black halos or pigment nodules often appear around it. The regional lymph nodes near the nevus are often swollen and palpable. At the same time, patients feel local itching and burning pain. If these changes occur in the body, you should seek medical advice immediately, preferably by biopsy. What kind of mole should I go to, and the younger the better? Most moles on the face or other parts of the body are benign, and you can "live in peace" with your owner without any treatment. But some moles need treatment. 1) The size of a super-large mole can sometimes predict whether it will cause trouble in the future. Studies have shown that larger moles are more likely to become malignant than smaller moles (except giant moles). 2) It is more likely that the mole that is easy to get will become a malignant mole. For example, pigmented nevus that grows on the hands and feet, neck, armpit, chest, head, back, genitals and other easily worn parts has a high probability of malignant transformation, so it must be observed regularly or removed directly to prevent malignant transformation and metastasis. 3) Sunlight or ultraviolet radiation may increase the chance of mole change, so it is best to remove moles from the parts that are obviously exposed for a long time. 4) The nevus growing on the soles of limbs is the most common part of melanoma. According to medical statistics, special attention should be paid to moles at the ends of limbs, such as those under fingers or nails. Most malignant melanoma in the East occurs in hands and feet. Therefore, if you find that the moles on your palms and soles grow abnormally fast, you must seek medical attention as soon as possible. 5) Unstable nevus is painful, itchy and discolored. 6) Congenital nevus People born with nevus are much more at risk of cancer than those born with nevus. In order to nip in the bud, experts suggest that people over 40 should do a self-examination once a month: take off all their clothes, hold a small mirror in front of the full-length mirror, and check the moles on the whole skin, especially if there are any newly discovered moles. Melanoma is characterized by irregular edges and irregular twists and turns; Not all black, but variegated and intertwined; At first, it is small and imperceptible, but it will gradually get bigger. A normal mole is neat and uniform black or dark brown, and it is easy to divide it into two symmetrical parts with a straight line. If melanoma can be found early, it can be completely removed under local anesthesia without worries. If it is a congenital giant nevus, it needs early treatment. There are several main reasons: ① the nevus cells of congenital giant nevus will migrate from superficial skin tissue to deep layer with age, so the younger the age, the shallower the location of nevus cells and the better the treatment effect; The older you get, the more nevus cells will penetrate into the deep tissue of the skin, and the more tissue you need to remove during treatment, the greater the loss. ② The absolute area of most patients with congenital nevus will increase with age, so the area to be removed will also increase with age, which increases the difficulty of treatment and reduces the effect of treatment. ③ Nevus are benign lesions with a very stable natural course. Malignant transformation is extremely rare in the course of nevus. However, the malignant rate of congenital giant nevus is high, which is 1% ~ 20% in domestic scholars and 1.2% ~ 42% in foreign scholars. No matter which specific data is accurate, in short, congenital nevus must be treated as early as possible to prevent malignant transformation. There are many ways to remove moles now. Which is better? The operation to remove moles can be different according to the size of moles. Small nevus (the size of rice grain) is best treated with medical Dot mole machine (carbon dioxide laser or high-frequency beauty instrument). Large moles (the size of peanuts) need to be removed and sutured by plastic surgery. At present, the methods to remove moles usually include chemical corrosion, electrocautery, freezing, laser and cosmetic surgery. If the cut mole is suspected to be malignant, it is best to send it for pathological examination to determine whether there is malignant change. If it is diagnosed as malignant black tumor by doctors, further comprehensive treatment is needed. What should Dot mole pay attention to in the future? Just after laser mole removal, there will be scabs locally, so we should pay attention to avoid local infection. Try not to touch water for the first two days. You can wash your face later, but you should wash it immediately after washing, and pay attention to avoid the sun. Generally, after one week, the scab on the surface can naturally fall off. Don't remove the scab yourself, or you will easily leave a scar. Can a particularly large mole or hairy mole be eradicated? What can we do? In particular, large moles and hairy moles are difficult to treat and can be eradicated, but they often leave scars. It can be determined according to the location, size and type of the mole. Some moles can also be removed by stages, and the skin defects formed after the removal of larger moles can be repaired by plastic techniques such as skin grafting, skin flap and skin expansion, which need to be treated in the plastic surgery department of a regular hospital.
