The upper arm of a person is the thinnest inside, and there is thin deep fat at the back. In general, fat is difficult to accumulate, but if fat accumulates in this part, it is difficult to remove it. It is easy to appear "kimono-like" or "bat-wing-like" deformity, that is, fat accumulation on the posterior and lateral sides of the upper arm, sagging skin, and thickening of subcutaneous fat on the adjacent back and side chest. Especially for people who often exercise, once they stop, it will cause serious fat accumulation in this part. The upper arm is centered on the humerus and surrounded by muscles that control the movement of the upper limb. The muscles on the front side are well developed, while the muscles on the inside, outside and back are very thin, and important nerves and blood vessels pass through the muscles on the inside. Most of the fat in the upper arm hangs on the back of the upper arm, and the fat in the shoulders and arms will continue to the elbow joint. The back of the upper arm is very close to important blood vessels and nerves. The surgical method of upper arm liposuction to lose weight is to make a small incision in the armpit to suck out the fat on the back and shoulders of the upper arm in layers and evenly. Liposuction of the upper arm is performed under local anesthesia. It needs to be bandaged for two days after operation and only needs to be changed once. The upper arm liposuction operation recovers quickly and has little effect on normal work and life. Precautions for obesity of upper arm liposuction ring: the superficial fat inside and outside the upper arm should be sucked evenly to construct a perfect upper arm shape; The middle part of the posterior side of the upper arm is easy to sag, so repeated suction should be avoided when liposuction is performed. The level of attraction should not be too shallow: there is no deep adipose tissue deposition in the forearm, so be careful in attraction. Excessive skin relaxation: liposuction should be performed on the upper arm first. If the skin cannot be retracted after operation, skin excision and plastic surgery can be used to avoid wrinkles on the skin. Seroma: Due to the formation of dead space and lymph overflow, the incidence of seroma after liposuction of upper arm is high, which can lead to skin sagging, so the time of wearing elastic clothes should be appropriately extended. The upper limb is an exposed part, and the puncture needle holes are few and hidden, so it is appropriate to attract it alone. /html/youhuihuodong/2009/ 12 15/2505 . html
