There is a limit, based on your weight, of the amount of local anesthesia that should be given. Some surgeons do not perform liposuction of the calves and ankles due to the length of time those areas stay swollen. Doingcircumferential surgery can also increase swelling. Second procedures can be done as soon as two weeks, unless there is a lot of swelling. You might want to go back to your surgeon and ask these questions.
I personally like to separate the thigh and calves as the swelling is HUGE when you do this all together. I suggest you see an expert who often stages procedures and treats large areas at once. Best, Dr. Emer.
This should be performed under general anesthesia all at once. Staged is not a good choice neither is oral sedation.
Under sedation the concentration of lidocaine can be lowered and most if not all can be done at the same time. Best of luck. If concerned, it can always be staged.
It depends upon your exam and your surgeon. Generally, circumferential thighs represent a very large body surface area requiring IV fluid hydration and anesthesia.
