What is Liposuction?
Liposuction also known as lipoplasty or liposculpture is the surgical removal of adipose tissue by the use of small metal cannulas.

What are the indications for liposuction?
Liposuction works best for treating localised fat deposits that do not respond to traditional diet and exercise. The treated areas will retain the new contours . Large volume of fat removal will also help reduce weight of the person.

If the fat is removed, will it return?
The body produces fat cells during three different periods: in utero, early childhood and early adolescence. In general, after reaching maturity the total number of fat cells in the body will not increase. Fat cells that are removed through liposuction or other techniques will not be replaced by other fat cells. So the resultant loss of fat & weight loss cells will be permanent.

What are the most common sequelae of liposuction?
The most common sequelae include contour irregularities, paraesthesias, oedema, ecchymosis & discoloration, which occur routinely in almost all patients who undergo liposuction. However, they resolve spontaneously or with minimal treatment such as massage & Pressure garment.

How much fat can be removed?
Whatever extra subcutaneous fat is there can be removed in a single sitting from different parts of body.

What is the postoperative care required?
No special care is required but one has to wear pressure garments for at least 3-6 months.

What is "wetting solution"? Why do we use it?
Wetting solution is the delivery of subcutaneous infiltration into the subcutaneous fat before the use of liposuction. It has two advantages: an anaesthetic effect secondary to the use of lidocaine and a haemostatic effect due to use of epinephrine.

Does the excessive skin need to be resected after removal of fat by liposuction?
In general, despite large amounts of fat being removed, skin has good elasticity and will reconfirm to the new underlying volume. However, in patients with inelastic skin or in older patients the skin may not redrape and skin resection may be needed.

What is the difference between ultrasound assisted liposuction and traditional liposuction?
Traditional liposuction removes fat cells through the mechanical avulsion of fat. Ultrasound assisted liposuction (UAL) uses an ultrasound generator and hand piece to produce USG energy to destroy fat cells in vivo through a process known as cavitation. The emulsified fat is then removed through a hollow channel in the cannula using standard suction.

When will the results be apparent?
The results of liposuction are usually seen after 3 weeks to 3 months and improvement continues even later.
