It is best to limit removal per surgery at 4-5L to ensure safety. Meticulous skill and technique are required for contouring rather than just simple fat removal. Best, Dr. Emer.
The American Society of Plastic Surgery has stated that a maximum of 5 liters of aspirate can be removed with liposuction in a single sitting. Board Certified plastic surgeons who wish to remain a part of our society will not take more. In my practice, a typical suctioning session will remove about 2 liters.Good Luck!
