Hello everyone, this time I will make an answer to several questions that people are more worried about after autologous fat transplantation: 1. After autologous fat filling, how long will the swelling be produced and when will it be able to subside? According to the process of changes in the body after fat transplantation, generally speaking, after autologous fat particles are transplanted to the appropriate site, it takes about 4 to 7 days to produce neovascularization, about two weeks, the blood vessels are able to penetrate deep into the center of the fat particles, and during this process, all of them may produce repeated swelling and absorption. In addition to personal constitution, age, menstruation, diet, emotions and other factors may also affect the production and duration of swelling. 2.Will there be any stiffness of expression after facial fat grafting? Generally speaking, there is a possibility of temporary stiffness of facial expression due to the swelling of the lipo injection site in the first week after the operation, but once the swelling period is over, generally there will not be any stiffness of expression because experienced doctors will avoid the damage of the needle to the nerves and blood vessels through their experience during the process of autologous liposuction, so as to avoid the stiffness of facial expression due to the damage to the nerves. 3.Will there be fat necrosis after autologous fat filling? Generally speaking, necrosis is not easy to produce, what is more likely to happen is liquefaction and absorption. If there are problems with the technology and technique of fat injection, too much fat is transplanted at one time or the injection is too concentrated, a large amount of fat is piled up together and the local blood supply is insufficient, it will lead to fat dissolution, liquefaction and absorption. So the way to deal with it is to transplant the appropriate amount of fat at one time, or multi-level, multi-point injection of fat, so that the fat can get enough blood supply, to reduce the possibility of this situation. 4.Will there be unevenness in the liposuction area after autologous fat surgery? Generally speaking, if liposuction is performed according to normal surgical specifications, there will be no unevenness in the liposuction area after surgery. The unevenness is mainly caused by the surgeon’s lack of experience and skill. At present, liposuction technology has been developed to a very standardized, as long as you choose a regular and reliable hospital, choose the surgeon with rich surgical experience, it is generally not easy to appear after liposuction liposuction area unevenness. Candidates should insist on wearing elastic garment for a long time after liposuction to shape the liposuction area, which can also prevent the unevenness of liposuction area after surgery. 5.How should I take proper care of the incision position after liposuction? After liposuction, the incisions may not heal well and scarring may occur. In addition to the patient’s own condition and system, as well as the standardization of the operator’s surgical operation, the patient’s care of the liposuction area and the liposuction incision also has a direct impact on the final result. For liposuction incisions, they should be kept clean, sterilized and coated with erythromycin ointment on a regular basis to prevent poor healing due to incision infection. At the same time, to prevent strenuous activities incisions and clothing friction, so as not to stimulate the formation of scar tissue. This will minimize postoperative problems in the liposuction area.
