Are frozen fat-dissolving, VASER plastic fat carving and radio back center effective?

Safe liposuction+perfect sculpture is the mainstream.

Body shaping is becoming more and more popular, including non-invasive and surgical liposuction. In order to achieve overall body shaping and actual fat removal, surgical liposuction is still the mainstream choice in the world. Because of the lack of professional training in plastic surgery, non-plastic surgeons can only deliberately emphasize non-invasive, such as cryoliposuction or liposuction auxiliary tools, such as laser liposuction, water knife liposuction and recent media so-called VASER plastic fat carving ... If we want to meet the requirements of plastic surgery, we still need orthodox and experienced plastic surgeons to completely liposuction, so as to achieve safe liposuction and perfect sculpture.

Another example is the invasive "VASER plastic fat carving" and the non-invasive "frozen fat dissolving" reported by the media. Is it effective? Can it replace surgical liposuction? Or is it just a flash in the pan? Vaser fat carving is an invasive ultrasonic method to dissolve fat in vivo, which uses low-frequency 36000 Hz ultrasound to tear fat tissue; Laser liposuction uses light energy to transform into heat energy to dissolve fat and liposuction in a large area, which can be used as an auxiliary tool for regular liposuction. The most important thing is to completely extract the fat, so as to achieve the perfect effect of liposuction and body shaping.

1 depth analysis: non-invasive degreasing method. Non-invasive methods with limited overall sculpture effect can be divided into six categories: 1. Radiofrequency ablation; Low intensity external laser therapy; And lipolysis by injection. 4. Frozen lipolysis) 5. Low intensity/low frequency nonthermal ultrasound. High intensity focused ultrasound (HIFU), etc. ...

High-frequency radio waves can't remove fat, which is commonly known as radio wave vest instrument in the market. Its principle is to destroy fat cells by heat energy, which needs repeated treatment. It can slightly improve the orange peel and the uneven distribution of fat in the shallow layer, but it needs to be improved by liposuction to reduce the thickness of deep fat. Frozen fat-dissolving: suitable for local use, requiring multiple treatments, and unable to carve as a whole.

The effect of one treatment may not be as good as that of regular liposuction surgery110, and its application scope is limited, so it cannot be applied to thighs; Compared with the same treatment range of abdomen, the effect is far less than that of surgical liposuction, and there are still side effects such as pain, redness, congestion and edema. It is pointed out in the literature that the principle of freezing and fat dissolving is that the solution tube filled with circulating freezing (controlled at -7 degrees) is attached to the copper plate, and the skin surface is tightly supported by the protruding copper plate, so that the temperature of fat cells is reduced to-2 degrees to 7 degrees Celsius, the fat in fat cells is frozen, and fat cells die through the inflammatory process. According to AVRAMM, the clinical study of lasers surg med 41:703-708 (2009) shows that the inflammatory reaction starts in about 3 days, reaches its peak in 14 days, and macrophages and phagocytes will devour dead cells in 14-30 days, and these processes last for about 90 days. There is a little improvement, but for patients who want to shape as a whole, although they have been treated by freezing and dissolving fat for many times, their satisfaction is often not high. It is best to add liposuction surgery to completely extract fat at one time to achieve perfect results. Frozen fat-dissolving in the market is only suitable for waist and abdomen, which is limited by the compression range of mechanical copper plate. Some areas are located between the two treatment areas, which are often ignored and cannot be completely improved. Therefore, after liposuction, whether in the treatment area or the non-treatment area without liposuction, the abdominal fat should be completely extracted through surgical liposuction, especially in the common thigh liposuction or butterfly sleeve, and frozen liposuction cannot be used in these areas.

Depth analysis 2: Non-invasive ultrasonic human sculpture can not be used as a whole. Human sculpture can be divided into two categories: 1. Low energy and low frequency nonthermal ultrasound II. High intensity focused ultrasound. At present, the FDA of the United States is doing under FDA review, but it can already be used in Canada and Europe. Low-energy and low-frequency non-thermal ultrasound: It uses mechanical pressure to generate alternating cycles of compression cycle (positive pressure) and expansion cycle (negative pressure) to cavitate and decompose adipose tissue, with low frequency (200KHz) and low intensity 17.5 w/cm2, such as Ultrashape contour I system (the third type).

High intensity focused ultrasound: using high frequency and high intensity to generate local rapid heat energy. Due to the nonlinear effect of ultrasonic beam, the speed of heat energy can be increased several times. The frequency is about 2MHz, the intensity exceeds 1000W/cm2, and the high frequency wavelength is about 1mm, which can focus the ultrasonic beam. For example, HIFU beam focused at 2 MHz can adjust the depth and generate heat energy, which can cause the effects of 10mm depth and 1mm diameter in adipose tissue, which will cause extensive contraction of collagen fibers and coagulation and necrosis of adipose cells. Each treatment area takes 45 minutes-1 hour, and the clinical effect begins to appear in about 2 weeks, with the best effect in 3 months. It can solve the shallow fat thickness of 1cm, but it can't improve the deep fat. The effect is slightly better than that of frozen liposuction, but the patient's satisfaction with the overall sculpture is not high. High-intensity focused ultrasound (HIFU) is suitable for the waist and abdomen, with some improvement, but not for the thighs. Radiofrequency ablation, low-intensity external laser therapy, injection of lipolysis and other side effects are unpredictable, which can cause severe pain, hematoma, allergic reaction, necrosis, scar and so on. Plastic surgeons should deeply understand the principles and limitations of various non-invasive liposuction, as well as the advantages and disadvantages of various auxiliary tools (electric assistance, water knife, ultrasound, laser liposuction, ultrasound-assisted), so as not to become obstacles and ignore the most important determinant of liposuction success.

Physician's conclusion: No matter which way you choose, consumers must understand that if you want to meet the requirements of body shaping, you still need to take out the fat through surgical liposuction. As for these six non-invasive methods, their application scope is local, which can only improve partial obesity and a little superficial fat, but can't deal with deep fat. Even after many treatments, the real effect of liposuction and body shaping can not be achieved. Invasive plastic liposuction (using ultrasonic principle), laser liposuction (converting light energy into heat energy), water jet liposuction and machine-assisted liposuction can all be used as auxiliary tools for regular liposuction.
