The most difficult part to recover after delivery is the protruding lower abdomen, which is mainly caused by 1 The skin is slack, showing obvious fat accumulation and stretch marks. 2. The fascia of rectus abdominis is relaxed, and the abdominal cavity is caused by excessive expansion during pregnancy. Say goodbye forever. If you want to improve the lower abdomen by liposuction, there will still be obvious wrinkles when the skin muscles are too loose. If you want to restore the flat abdomen and charming waistline when you were a girl, you may need to consider abdominal plastic surgery, that is, abdominal pulling surgery. This kind of surgery mainly uses surgery to tighten the loose abdominal muscles, tighten the excess abdomen to the abdomen, and remove the excess skin, so as to effectively reproduce the beautiful curve between the waist. Abdominal plastic surgery has four degrees, and there are different treatment methods according to the status and degree of abdominal protrusion. Simple fat accumulation, just liposuction can flatten the abdomen without leaving scars. 2. Abdominal skin is normal or slightly slack, rectus abdominis fascia is slightly to moderately slack, and there may be fat accumulation. Endoscopic abdominal plastic surgery can be used to tighten fascia and liposuction. The wound is located above the pubic bone, about 4 cm long, and it is not easy to be found. 3. The skin of the lower abdomen and fascia of rectus abdominis are moderately relaxed, and stretch marks are concentrated in the lower abdomen, which may be accompanied by fat accumulation. The treatment method is "moderate abdominal plastic surgery", also called "local abdominal plastic surgery", which mainly tightens the aponeurosis and removes excess skin, and liposuction will be improved more obviously. The surgical wound is about 15 cm, which can be delivered by caesarean section. 4. The skin of upper and lower abdomen and fascia of rectus abdominis are severely relaxed, with obvious stretch marks. And "standard abdominal plastic surgery" is also called "total abdominal plastic surgery". If the fascia is tight and excessively relaxed, more skin needs to be removed, and there will be 25 ~ 30 cm surgical scars above the pubic bone. And because there is a lot of skin removed, the navel must be redone to avoid the skin being too low or deformed after tightening. In addition, if you need to cooperate with abdominal liposuction, you have to wait for 3 ~ 6 months to avoid affecting wound healing.
