Cellulite is not usually improved by traditional liposuction and in some cases may be made worse. The method of surgery is to make small incisions through which the fat is removed in individual tubes. Different sized cannulae are used to remove the fat and the pattern crisscrosses to reduce the risks of irregularity. You can choose but most patients are are more comfortable asleep. Most of the time this is an outpatient operation and a stay in the hospital is not needed.
All operations have some risk.
The risks of surgery are divided into two groups. First those that are seen in all operations and second those that are unique or special for this operation. In the first group, the main risks are swelling, bruising, bleeding, infection, a scar and numbness or change in feeling. The main problems which are special for this operation are surface irregularity and the need for secondary surgery. Ultrasonic liposuction also has complications such as nerve damage but probably causes less bleeding and irregularity.
