Lead: Obesity significantly affects people's physical beauty and may lead to many diseases. Shaping the ideal body shape is the pursuit of many obese people. In recent years, medical beauty methods and measures for obese people have emerged one after another, among which liposuction is the most commonly used and reliable method to lose weight and shape. 1. Abdominal liposuction The abdomen is the easiest place to accumulate fat. Women's fat mostly accumulates in the lower abdomen, while men mainly accumulate in the upper abdomen. It has been reported that abdominal fat cells are more involved in metabolism in the body, and people with more abdominal fat are prone to diabetes, myocardial infarction and stroke. Abdominal liposuction is the most common part of liposuction surgery. Abdominal subcutaneous fat can be divided into shallow and deep layers, with more deep layers. Abdominal liposuction incision can be located around pubic mound or umbilical foramen; Incision on both sides of umbilicus or incision on both sides of umbilicus can also be used. The advantage of incision on both sides of navel is that it can suck waist fat at the same time. Abdominal fat accumulation is often larger than other parts. It should be noted that liposuction is a kind of harm to human body. The greater the suction, the greater the suction area, and the greater the harm to human body. If the amount of fat to be sucked is large, it can be done in stages, and the amount to be sucked at a time should not be too large. 2. Waist liposuction The waist is also a place where fat is easy to accumulate. Fat people generally have more fat around their waists, which makes them round and thick. The deposition of subcutaneous fat in the waist is mainly deep fat. CT examination shows that the deep fat in the waist accounts for about 70% of the deep fat in the skin. Deep adipose tissue is static adipose tissue, which is easy to synthesize but not easy to decompose. It is difficult to remove waist fat by non-surgical method. Liposuction is an effective method to remove fat. Incision position can be used on both sides of the waist; You can also use the incision on both sides of the navel or the incision on both sides of the navel to suck out abdominal fat at the same time. 3. Liposuction on the buttocks, thick skin, rich superficial sebaceous glands and developed superficial fascia, is a fibrous adipose tissue. Women's buttocks are more likely to accumulate too much fat, especially sedentary women, and obese men tend to accumulate too much fat. Too much fat accumulation in the buttocks will often form breeches-shaped buttocks, which will lengthen the buttocks and affect the normal hip curve. The incision position of hip liposuction is generally located above the gluteal groove. 4. Thigh liposuction The superficial fascia in the front of the thigh contains a lot of fat, and the thigh is one of the common parts prone to abnormal accumulation of fat. In the thigh, both shallow fat and deep fat exist. The position of thigh liposuction incision is selected at the junction of the lower edge of inner shorts and the front thigh, or below the inner thigh. 5. Liposuction on the face and neck: The subcutaneous fat of orientals often accumulates on the cheeks. In addition to the increase of fat pads on both cheeks, superficial subcutaneous fat also thickens to varying degrees. The neck, especially the mandible, is easy to pile up to form a double chin showing old age. Facial and neck liposuction has obvious effect on shaping facial and neck contour and rejuvenation. The common suction range includes the fat in buccal maxillary sinus and parotid gland, and the accumulated fat tissue can also be seen in zygomatic region and mandibular angle, and other parts such as nose, forehead and lips. Facial liposuction often uses low negative pressure suction and small diameter suction needle, such as syringe liposuction, to reduce unevenness caused by excessive suction. The face is rich in blood vessels and nerves, which may cause nerve damage. In addition, the face is the only part that can't be covered, and any defects are obvious. Therefore, liposuction of the face and neck requires exquisite technology, and attention should be paid to choosing qualified medical institutions and experienced doctors.
