Ms. Sun gave birth to twins when she was young. Now that people are in middle age, she feels more relaxed. Can she smooth her stomach by liposuction? In the abdomen, if fat accumulation is combined with abdominal sagging, or due to lack of proper exercise and maintenance after delivery, stretch marks appear in the abdomen, and liposuction will make the abdomen relax even more. At this time, we must turn to abdominal plastic surgery to achieve the purpose of abdominal plastic surgery. Abdominal plastic surgery has undergone decades of changes, and the surgical methods are constantly innovating. At present, there are three commonly used methods: 1. Traditional abdominal lifting operation: this operation is suitable for patients with obvious abdominal drooping or stretch marks. Its practice is to cut the lower abdomen horizontally along the upper edge of pubic hair, and the knife edge extends to the waist on both sides, and then peel the abdomen upwards. At the navel, the navel must be separated and cannot be cut off. Then find out the loose rectus abdominis muscle, sew its muscle membrane to the center to tighten it, so that the waist is bound inward, then tighten the whole belly downward, cut off the excess belly, including the stretch marks on it, and then plant the navel to make it return to its original position. Finally, sew up the knife edge and hide it in the abdomen that underwear can cover. 2. Mini-abdominal lift: This operation is suitable for patients with mild abdominal relaxation below navel. The method is to make a transverse incision of about 15 cm along the upper edge of pubic hair in the lower abdomen, then peel off the abdomen upwards, sew up the loose muscularis rectus abdominis, then pull down the abdomen, remove the redundant abdomen, and sew up the wound to complete the operation. 3. Endoscopic abdominal plastic surgery: this operation is suitable for those who have no abdomen and no relaxation, but have obvious relaxation of rectus abdominis, which makes it difficult to defecate in the abdomen. The method is to make a small incision of about 3 cm on the upper edge of navel or pubic hair, stretch into the endoscope to peel off the abdomen, find out the loose rectus abdominis, sew it to the midline and tighten it to complete the operation. 4. If there is fat accumulation in the lumbar fossa, or when endoscopic abdominal plastic surgery is considered, liposuction combined with abdominal plastic surgery will achieve the perfect effect of overall plastic surgery of abdomen and waist. Abdominal plastic surgery is a major cosmetic surgery, and preoperative evaluation needs to be very cautious. If the patient is obese, lose weight first. If there is hypertension or diabetes, control it stably first, and then select the most suitable operation method after analysis and evaluation by a qualified plastic surgeon. Then abdominal plastic surgery should be quite safe and highly satisfactory. The possible complications during the operation include seroma, local skin necrosis, wound dehiscence, scar hyperplasia and the most serious fat embolism, but these complications can be avoided in advance or properly handled by experienced plastic surgeons.
