1 Ms. Wang consulted: After I had a child, my waist and abdomen have grown a lot of fat, and I can’t wear nice clothes, so I deliberately control my diet and take diet pills without any effect. I’d like to ask the expert if liposuction is suitable for my situation. What is the effect of liposuction and is it easy for obesity to recur? How about liposuction in winter? The first thing you need to do is to take a look at the results of liposuction. Liposuction originated in Europe and has a history of more than 100 years. It is divided into sharp liposuction and blunt liposuction due to the different directions of the opening at the front of the liposuction needle. Later, with the use of swelling anesthesia, the bleeding problem during the surgery was largely alleviated and the safety of the surgery was guaranteed to a great extent, while the amount of single liposuction and the areas treated were continuously expanded. Because of this, the complication rate of liposuction surgery is also higher in some cases where the single treatment area is blindly expanded. This situation occurs mainly because many friends have some misunderstandings about liposuction. Because fat cells are actually a kind of lifelong cells, the number of fat cells generally does not increase during the lifetime, and the obesity of our body is caused by the increase of fat cell volume. While liposuction can reduce the number of fat cells, it can also selectively remove fat accumulation in certain areas and remove only those deep fat tissues that are not easily consumed by exercise and dieting. So liposuction objectively plays a role in weight loss, but in essence it is a method of removing local fat accumulation and restoring body curves, that is, a method of body contouring. Because of this, patients with localized obesity are more suitable for this method, while patients with uniform obesity have less desirable results. As mentioned above, the area after liposuction will not rebound individually, but of course it will grow proportionally with the overall body fatness. Liposuction currently has no clear time limit for surgery, and since it is necessary to wear elastic clothing that helps restore the elasticity of the skin after surgery, it is more convenient to use elastic clothing in winter because it is thicker to wear, so it is more suitable for liposuction surgery. 2 Ms. Li consultation: my calves have been very thick, colleagues often say that I am “elephant legs”, I have tried a lot of methods to slim legs, hot water soaking massage, jump rope, jogging, but the calves are still not fine. I want to consult experts, “elephant legs” can not be improved? Why can’t the methods I use to slim my legs make my calves thinner? Hello Ms. Li, the problem of leg shaping has been troubling many women who love beauty, and also troubling many plastic surgeons, because it is really a very difficult problem. Calf tissue hypertrophy can be divided into two categories: congenital and acquired, and can also be divided into three categories: fatty, muscular and mixed fat-muscular from the specific tissue of hypertrophy. Since calves do not have the same subcutaneous fat accumulation as other parts of the body, and the subcutaneous tissue is thin and rich in lymphatic and vascular distribution, calf muscle hypertrophy is often its main cause. By the methods you mentioned alone, of course, can not solve the problem of muscle hypertrophy, especially for those who are congenitally hypertrophic. The main methods currently used to solve this type of problem are calf fat aspiration, botulinum toxin local injection, partial calf muscle excision, selective nerve cut calf bariatric surgery, radiofrequency ablation selective nerve blocking, etc. The reason there are so many methods is that there are no methods with particularly excellent results. All these methods inevitably have problems such as local skin uneven standing and recurrence after surgery. The latter methods, in particular, can even produce functional effects and the risk of irreversible damage. Therefore, when choosing treatment for calf shaping, you must be careful and cautious. 3 Mr. Zhao consultation: I am a typical “Chinese character face”, both sides of the cheeks look particularly wide, I would like to ask the doctor to answer the question, through plastic surgery can make too wide face look thin? Will the plastic surgery affect my normal eating and speaking? Hello Mr. Zhao, the treatment you mentioned is called facial contouring in the field of plastic surgery. We Chinese belong to the Mongolian Asian race, and our facial features are prominent cheekbones and wide jaws, especially on the lower face. Due to the increasing integration of Eastern and Western cultures in recent years, the aesthetics of the Chinese people are becoming more and more westernized, and the treatment of the “Chinese face” is receiving more and more attention. The current treatment is based on jaw angle osteotomy and botulinum toxin injection treatment. Among them, Botox injection is for simple bite muscle hypertrophy, both sides of the bite muscle is not symmetrical treatment of friends, simple operation, non-invasive, the effect lasts for six months, does not affect normal work and life. Of course, because the action time of Botox is half a year, it needs to be injected again after half a year. The jaw angle osteotomy is one of the well-known plastic surgery procedures, which can improve the shape of the jaw edge by removing the bone of the jaw angle that is too wide or even turned out, and separating the inferior stop of the bite muscle to improve the shape of the jaw edge. Since the surgery requires an intraoral incision and removal of the bone, a liquid diet is required for 1-2 weeks, without affecting speech.
