In our daily consultations, we often encounter many friends with depressed scars on their bodies. What is a depressed scar? Clinically, it is explained as a scar caused by a defect in the dermis and subcutaneous tissue. Acne, surgery, trauma, infection, chicken pox and smallpox are common causes of depressed scars. These causes lead to defects in the dermis and subcutaneous tissues of the skin, and the subsequent loss of collagen and elastin during the healing process will leave permanent depressed scars. Generally, depressed scars are classified into larger depressed scars and smaller depressed scars. So how should we treat these two types of depressed scars? Let’s talk about them separately. We often use the following methods to treat large depressed scars: 1. Peeling and fat filling Larger depressed scars have generally reached the subcutaneous superficial fat area. After stripping to the superficial subcutaneous fat layer to break the adhesions and artificially create a local cavity in the scar tissue, autologous fat is used to fill the scar, which is a more common method to treat large depressed scars in a strictly aseptic environment with simple operation and small trauma, and does not affect daily activities after surgery. 2.Stripping with super reduction fine suture Some parts of depressed scars are not suitable for fat filling, such as forehead, foot surface and so on. Then it is necessary to cooperate with super tension reduction fine suture technique. After breaking the adhesions with peeling, there must be an influx of fresh blood, which contains a lot of inflammatory cells and cytokines that not only improve the blood circulation in the area, but also have a positive restorative effect. Not only that soon after the traumatic inflammation appears, the granulation tissue formed by fibroblasts, endothelial cells, and neovascular tissue will fill up the cavity, and after the recovery with super-reducing fine suture is a very thin line, and the normal social distance is not obvious, to achieve the purpose of scar repair. In addition, large depressed scars can also be treated with fractional laser with photon therapy. With the development of laser equipment technology, depressed scars can be treated by ultra-pulse fractional laser, ion beam and other photoelectric equipment to achieve better results. If we compare a depressed scar to a plate, we apply the laser to grind the plate along the edge to make it more shallow, and also stimulate the center of the plate to promote subcutaneous fibroblasts and collagen proliferation to thicken the dermis, which can achieve a double effect. In clinical practice, it is actually more common to see some small depressed scars, which are often referred to as acne pits and pockmarks, so how should such scars be treated? 1, peeling surgery plus laser repair As mentioned above, peeling surgery breaks the adhesions in the subcutaneous fat layer after fresh blood fills the cavity, self-repair, and then with laser treatment of acne issuing red, dark pigmentation, all can achieve very good results. 2, filling repair depression scars Because of depression, the most direct method is to fill! The so-called lack of what to fill, especially for the dermis is not obvious adhesion, defects, but only the amount of subcutaneous tissue is not enough, we can fill through hyaluronic acid, collagen and other implants for injection, so that the depressed part of the augmentation, so as to harmoniously articulate with the surrounding skin, restore These are only common methods of treatment of depressed scars, but no matter which method to take, in addition to be sure to go to the regular plastic surgery hospital for consultation and treatment In addition, it is also necessary to listen to the advice of a professional doctor, and the combination of multiple methods can achieve twice the result with half the effort.
