Popularity of liposuction for unwanted fat removal has generated demand for better technology which can make liposuction safer, painless and quicker. Patients and plastic surgeons alike have constantly seeked solutions that can make liposuction a better and more satisfying procedure. VASER is the latest technological offering in this context.
VASER has been around since 2002, when it was approved by USFDA for fat removal. And no, VASER has nothing in common with similar sounding LASER, which also has been used for liposuction. VASER stands for Vibration Amplification of Sound Energy at Resonance. Simply put it adds the benefit of ultrasound technology to the standard liposuction procedure. Ultrasound waves are sound waves at specific frequency and one commonly comes across it during ultrasound cleaning of dental plaque and while looking at the growing baby in mother’s womb. Usage of ultrasound for liposuction itself is not new. Ultrasound assisted liposuction ( UAL)was very popular in eighties. Vaser has resurrected ultrasound in liposuction. Vaser is 4th generation ultrasound assisted liposuction technology which offers more safety than earlier ultrasound technologies. Speciality of Vaser is “ liposelection” – meaning it caused damage to fat cells only without damaging other tissues.
Vaser liposuction is a surgical procedure like the good old liposuction, only technology and results differ. VASER is performed in sterile operation theatre by qualified plastic surgeon. General or local anaesthesia is used. Tumescent solution which may contain local anaesthetic is injected into the fat to be liposuctioned. Injection of tumescent solution shrinks blood vessels, provides anaesthesia and also creates safe environment for VASER by completely soaking the fat tissue.Vaser probe, which is a solid titanium rod of 3-5mm diameter is then introduced into the fatty layer through small 3-5 mm cuts in the skin. The ultrasound energy is delivered at accurate dosage at the tip of the probe, while moving the probe through fat in all layers all over the area. Ultrasound energy selectively destroys fat cell membrane and liquefies fat. Since the blood vessels, nerves and skin are resistant to lower doses of ultrasound, they are safe. Liquified fat is then vaccumed out with hollow suction metal cannulas attached to vaccume suction machine.
Depending of how much fat was removed VASER liposuction can be a same day surgery or may require hospitalization. Antibiotics and painkiller tablets are prescribed and usage of compression garments is mandatory for 1 month or more after VASER liposuction.
Tissue swelling is natural after any surgical procedure. After VASER liposuction results are seen gradually over next one month onwards as gradually swelling comes down and skin retracts. This is facilitated by wearing compression garment.
So what is the special advantage of VASER liposuction? Vaser liposuction enables larger amounts of fat removal which was hitherto unsafe due to blood loss. So one can have more fat removal, without the need for blood transfusion. Recovery after large liposuction is faster with VASER. Vaser also allows for better sculpting in tougher and fibrous areas like back and male abdomen. High definition liposculpture with VASER is gaining popularity for creating six pack abdomen look. Vaser has been used in more than 100,000 procedures all over the world and has proven to be safe.
