The time required to perform liposuction may vary considerably, depending on the size of the area, the amount of fat being removed, the type of anesthesia and the technique used..
Liposuction is a procedure in which localized deposits of fat are removed to recontour one or more areas of the body. Through a tiny incision, a narrow tube or cannula is inserted and used to vacuum the fat layer that lies deep beneath the skin. The cannula is pushed then pulled through the fat layer, breaking up the fat cells and suctioning them out. The suction action is provided by a vacuum pump or a large syringe, depending on the surgeon's preference. If many sites are being treated, your surgeon will then move on to the next area, working to keep the incisions as inconspicuous as possible.
Fluid is lost along with the fat, and it's crucial that this fluid be replaced during the procedure to prevent shock. For this reason, patients need to be carefully monitored and receive intravenous fluids during and immediately after surgery.
Technique
Fluid Injection, a technique in which a medicated solution is injected into fatty areas before the fat is removed, is commonly used by plastic surgeons today. The fluid helps the fat be removed more easily, reduces blood loss and provides anesthesia during and after surgery. Fluid injection also helps to reduce the amount of bruising after surgery. The amount of fluid that is injected varies depending on the preference of the surgeon.
All Surgery Carries Some Uncertainty and Risk
However, it's important to keep in mind that even though a well-trained surgeon and a state-of-the art facility can improve your chance of having a good result, there are no guarantees. Though they are rare, complications can and do occur. Risks increase if a greater number of areas are treated at the same time, or if the operative sites are larger in size. Removal of a large amount of fat and fluid may require longer operating times than may be required for smaller operations.
The combination of these factors can create greater hazards for infection; delays in healing; the formation of fat clots or blood clots, which may migrate to the lungs and cause death; excessive fluid loss, which can lead to shock or fluid accumulation that must be drained; friction burns or other damage to the skin or nerves or perforation injury to the vital organs; and unfavorable drug reactions.
The scars from liposuction are small and strategically placed to be hidden from view. However, imperfections in the final appearance are not uncommon after lipoplasty. The skin surface may be irregular, asymmetric or even "baggy," especially in the older patient. Numbness and pigmentation changes may occur. Sometimes, additional surgery may be recommended.
