Abdominoplasty is a fold formed in the bikini line area after laxity of the abdominal wall, and the surgery involves the removal of excess skin, which involves: 1. overall skin thickness reduction. 2, Excision of the excess skin. 3, a number of years after the birth can not return to the prenatal state, the need to do the tightening of the anterior rectus abdominis muscle. How much skin removal is more appropriate? How big should the incision be? In fact, it depends on the degree of skin laxity, if mild laxity, about ten to fifteen centimeters, do a shuttle-shaped excision, and then the overall abdominal wall thinning. If it is very lax, an incision will need to be made from the anterior superior iliac spine and the length of the incision is usually about 15 centimeters, the longest I have done is nearly 20 centimeters. At this point, some candidates will think about what to do with their belly button if their stomach is cut. We do surgery is limited in the scope of separation, usually to the edge of the rib cage, and then pull the loose skin down, the navel part also need to be cut, after the excess skin is cut off, we will be in the navel in the corresponding location to reshape a navel, the shape will not have a major impact. Some candidates will ask, teacher you did not previously talk about liposuction after the skin itself will have a certain retraction, why do abdominoplasty which? After liposuction, due to the stimulation of the surgery, there will indeed be a certain amount of local elastic retraction, which is a characteristic of the skin itself, but there is usually a certain limit, generally the fold can not exceed two centimeters. However, if it has reached five centimeters and it is so hot that you get heat rash under the skin in summer, this needs to be surgically removed. The longer the incision, the higher the chance of seeing it, but it is usually invisible in summer when you wear a bathing suit or something. What are the risks of surgery? First of all, there are risks associated with any surgery, and the risks of abdominoplasty include problems with abdominal wall necrosis, skin necrosis, etc. When dealing with it, you should be careful not to have too much tension, with deep fat as the main layer and superficial fat as a supplement, not to pull too tightly, and never to pursue the extreme.
