Liposuction Introduction Liposuction, also known as liposuction, is the most common plastic surgery procedure that uses negative pressure to remove excess localized fat from the body for the purpose of beautifying the body. It is relatively safe because the operation is limited to the subcutaneous fat layer, where there are no large blood vessels or major nerves. The surgery is performed by trained plastic surgeons in regular hospitals according to strict sterile and non-invasive operating principles and is generally not harmful to the body. Liposuction is not only the use of modern surgical techniques and advanced medical equipment to suck out excess fat from under the skin of the body, but its ultimate goal is to reshape the body according to aesthetic standards in order to restore the original beautiful body to the maximum extent possible! Liposuction is particularly suitable for women and men who are relatively normal in weight but have excessive, disproportionate localized fat. These localized fat deposits may be a genetic trait that does not respond to weight loss or physical exercise. Liposuction may be the only way to get rid of them. Liposuction can be performed at almost any age, as long as your skin has enough elasticity to restore a smooth appearance after fat removal. If your skin does not have enough elasticity, or if your skin is excessively saggy and does not return properly after liposuction, you will need a skin excision and tightening procedure. Am I a candidate for liposuction? Liposuction is indicated if you have excess fat in the following areas or if you desire to contour the following areas: cheeks, jaw and neck, upper arms, breast and chest areas, shoulders and back, abdomen and waist, hips and buttocks, inner and outer thighs, inner knees, calves and ankles People who are obese and overweight can also improve their body shape and contour with liposuction. Liposuction can also reduce the risk of diseases caused by obesity such as diabetes and hyperlipidemia. Liposuction can be used to treat male breast enlargement, a condition that often occurs in adolescent and adult males and causes severe psychological burden to patients. Liposuction is also commonly used in scar repair and for macromastia due to increased fat, among other things. Liposuction is not a substitute for a total body bariatric procedure, nor can it deal with skin irregularities caused by fat mass accumulation. Liposuction can be performed on multiple parts of the body at one time, or at the same time as other cosmetic surgery procedures. The use of the aspirated fat, after separation and purification, is injected into the temporal area, cheeks, lips, upper lids, earlobes, breasts and other areas to fill depressions or to achieve augmentation of organs, which is called autologous granular fat injection transplantation. Since autologous fat is used, there is no risk of rejection or cross-infection. What should I look for during my visit? Due to individual physiological differences, the results of liposuction are not necessarily the same for everyone. Since liposuction is a cosmetic procedure, each person requires different results. Please be clear about your requirements and tell your surgeon exactly what areas you need to improve. The plastic surgeon will discuss with you and choose the best surgical option for you based on your individual characteristics. What should I tell my surgeon after deciding to opt for liposuction? You should give your doctor a detailed and faithful account of your medical history, including medical conditions such as the presence of diabetes, high blood pressure or heart disease. Your doctor will also want to know about your previous surgical history, the various types of weight loss medications food and physical therapy you have received, and any other medications you are currently taking. The physician will also need to know your current weight and whether you plan to lose or gain weight in the future. The physician may also want to ask about changes in the appearance of these areas after previous weight loss. What should I expect before and after my liposuction procedure? You should stop smoking and stop taking all types of medications that tend to cause bleeding for at least 2 weeks prior to surgery. The surgery should be avoided during menstruation. It is best to have someone to drive you to and from the outpatient surgery and to have someone with you the first night after the inpatient surgery. You will be able to get out of bed the day after surgery. However, strenuous or excessively intense activities should be avoided for a short period of time. You should still stop taking drugs that can cause bleeding, such as aspirin, and refrain from smoking for a week after surgery. 5-7 days after surgery, the dressing can be removed and replaced with elastic clothing for 2-3 months. How is liposuction performed? Before liposuction, the surgeon marks the area to be liposuctioned or contoured. Then a swelling solution is injected into the area to achieve anesthesia and swelling of the tissue. Small incisions of 2-4mm are then made in hidden areas of the skin, and a liposuction needle is inserted to suction out the fat under the skin through reciprocal movements and a negative pressure device. After the suction is finished, a sterile dressing is applied under pressure to provide a good retraction of the skin that appears saggy after liposuction. What are the risks of liposuction? The treated area after liposuction often has reduced skin sensation, swelling and bruising, and in some patients the skin surface may be slightly uneven or stiff; these conditions usually recover on their own within 3 months after surgery. The more serious complications that can occur with surgery include hematoma, seroma, infection, anesthetic toxicity and even fat embolism. There are risks associated with any surgery. Although the most serious complications of liposuction are fatal, the risks of liposuction are actually minimal and it is the most common and accepted cosmetic surgery procedure. How much will liposuction affect my work and life? If you choose outpatient surgery, you will be able to go home the same day of surgery with moderate activity, bed rest is not advocated and most patients are able to resume normal activities after two or three days. If liposuction is extensive and you choose inpatient surgery, including the time before and after hospitalization, you are prepared to be out for three or four days will be sufficient. The post-operative elastic garment may make you feel urgently uncomfortable, the swelling for several days may make you less mobile, and the stiffness and unevenness of the skin for two or three months may make you doubt the results of the procedure. Don’t worry, all discomfort is short-lived and temporary, and you will soon be able to enjoy the amazing results of liposuction. Will I rebound after liposuction? The fat layer under the human skin is divided into the cellular layer (superficial) fat and the platysmal layer (deep) fat. The superficial layer of fat is located in the subdermal layer widely distributed throughout the body, thickens when obese, and is vital to the elasticity and contractility of the skin. It is metabolic adipose tissue, changes with weight changes, and is easily synthesized and stored as well as easily decomposed. Deep fat is located between shallow fascia layer and myofascia, exists in some parts of the body, related to heredity, it is stationary fat easy to synthesize but not easy to decompose, in women it is often located around the pelvis as follows: abdomen, waist, buttocks, rotor, in men it is mostly found in the upper abdomen. (Judgment method: after dieting and weight loss, the area where fat accumulation still exists is the best area for fat aspiration.) Therefore, diet, exercise, weight loss drugs and other non-surgical weight loss methods can only make the fat cells smaller in size, but not reduce their number. Once this weight loss method is interrupted, not only will it fail to achieve the purpose of weight loss, but it may form a vicious cycle of losing more and more weight. Fat aspiration is a mechanical method that effectively removes deep fat (resting fat) and reduces the number of fat cells, and its effect is permanent, so the aspirated area will never stand out as it did before the aspiration. As long as you do not gain weight drastically, the liposuction effect is permanent. From this point of view, there is no “rebound” problem with liposuction. What else should I expect after liposuction? You should stay in close contact with your surgeon, ask questions, follow up with him or her, and make regular follow-up visits to evaluate your condition. Contact your physician in time for your next surgery appointment so that both of you can schedule a reasonable amount of time to ensure a smooth implementation. What is liposuction for breast augmentation? What else can fat injections treat? The fat extracted by negative pressure is granular with many intact fat cells. These fat cells can be injected into the submammary gland or subcutaneously, firstly, they are nourished through tissue exudate, and later on, the blood vessels are generated, the fat tissue becomes viable and the volume of the mammary gland is maintained. Since it is autologous tissue, there is no rejection side, and it is safe and reliable. However, the injected tissues cannot be completely revitalized and some of them will be absorbed by the organism, so to get the ideal size of breast, multiple injections are needed with an interval of about 2 months each time. In addition to breast augmentation, fat injection can also fill in the body surface including some sunken deformities of the face, such as the temple area, forehead, etc. In addition, fat injection can augment lips, fill in deep nasolabial folds and wrinkles, etc. Liposuction can treat male breast enlargement With the improvement of living standard, the number of obese people is increasing, and the number of male breast enlargement patients is also increasing. Male breast enlargement occurs mostly in young people and seriously affects the psychological health of adolescents. Patients often have a hunched chest and are reluctant to go to public places or participate in group activities. Surgical treatment is often surgical excision, with large incision scar and often pitted areas. Currently, we use fat aspiration to treat gynecomastia, which is a safe and simple procedure that can be performed on an outpatient basis without hospitalization, and does not interfere with work or study after surgery, with good surgical results. Liposuction can help treat scarring The common methods of repair for slightly larger scars are: split excision, skin grafting, flap transfer, skin expansion, etc., which either require multiple surgeries and a long period of time, or suffer from additional scarring that has to be added during treatment. We have applied fat aspiration to scar repair for the first time, removing a large area of scar for most patients at one time, avoiding the drawbacks of previous treatments. Fat aspiration can treat large breasts Normal breasts are hemispherical, with the upper boundary in the second rib, the lower boundary in the sixth rib, the near middle boundary in the lateral sternum line, and the outer boundary in the anterior axillary line, with a weight of about 250 to 350 grams. Breasts that exceed this boundary and are larger than this weight are considered gigantomastia. Breast enlargement can cause mental and physical pain to the patient. Patients often experience neck and back pain, difficulty moving around in daily life, fatigue, and the skin underneath the breast and below the inframammary fold is often moist and uncomfortable, even forming eczema. Patients often suffer from low self-esteem. At present, in addition to the use of horizontal double-tip flap method, vertical double-tip flap method and other surgical methods, we also developed the application of fat aspiration to perform breast reduction plastic surgery. This method has the following advantages. 1, no hospitalization, outpatient can perform this surgery, saving time and costs for patients. 2, the surgery is less traumatic, after surgery does not affect daily life and work. 3.No obvious surgical scar, in line with cosmetic standards. 4.Less postoperative complications and less pain for patients. 5.Satisfactory surgical effect.
