Vaser LipoSelection (VL) is a modern and effective liposuction technique that utilizes ultrasound energy to break down the fat and liquefy it before it is removed by vacuum suction. The ultrasound energy is delivered via a rod-like probe that is inserted directly into the fat. After the fat has been liquefied, a suction cannula (tube) is used to remove the fat.
Liquefying the fat confers a tremendous advantage because it greatly facilitates its removal, because liquid fat is easier to suck out than more solid fat. Thus, the fat can be more thoroughly removed. This ensures that the debulking objective of liposuction can be well achieved. In addition, from a body contouring standpoint, it is easier to create smooth contours when removing the fat, because liquid fat is easier to remove uniformly than solid fat. This advantage helps to minimize the risk of post liposuction uneven contours.
Another important benefit of the ultrasound energy is that it heats up the collagen fibers that connect the underside of the skin to the muscles below the fat. The heat causes the collagen fibers to shorten, pulling the skin inwards and effectively tightening the skin.
VL is very versatile and can be used to treat virtually any part of the face or body that has excess fat. Apart from commonly treated areas such as the abdomen, waist, love handles, saddle bags, inner thighs and arms, it can also be used to address the double chin, face, bra fat, knees and gynecomastia (unwanted breast tissue in the male).
Finally, VL can used to create highly defined abdominal contours in both male and female patients, such a tube packs in females and six packs in males.
Dr Huang has more than twenty years of experience with liposuction and more than fifteen years of experience with VL, so you can rest assured that you will be in the hands of an experienced user of this technique.
A few small incisions (less than one cm each) are made in strategic locations to minimize visibility of the scars. The areas to be addressed are first infiltrated with a saline solution containing long acting local anesthetic and adrenaline. The fluid causes the area to become swollen (tumescent), causing physical expansion and loosening of the fat and constriction of blood vessels by pressure. The tumescent effect thus facilitates fat removal and reduces bleeding. The local anesthetic ensures that after the surgery pain is well controlled. The adrenaline further reduces bleeding by causing blood vessels to go into spasm.
Next, the ultrasound probe is inserted into the fat through the same incisions and moved back and forth in a fan shaped pattern while the ultrasound energy is delivered. After this, a suction tube (cannula) is inserted and moved back and forth while the vacuum suction removes the liquefied fat. The wounds are then closed with fine sutures.
The length of the procedure depends on how many areas are operated on and the amount of fat removed. It can range from less than an hour for a single small area to many hours for large or multiple areas. Small areas can be carried out under local anesthesia or intravenous sedation, whereas large and multiple areas are best addressed under general anesthesia. It is completed as a day surgery procedure when less than two liters of fat are removed in total. For larger amounts of fat removal, hospitalization is required.
