Fat transfer can be done under local anesthesia. It all depends on the patient and what they can tolerate. This is something to talk about with your surgeon. The American Society of Plastic Surgeons is specific on where we should operate to be safe surgeons. These are good guidelines and should be followed. If you are getting IV sedation you should be in an accredited facility. Costs a bit more, but this is appropriate. You will hear lots of answers on the harvested question. I will quote the great Dr. Russell, who said that "when there is more than one way of doing something no one way is best." There are plenty of different ways of collecting the fat. Some things make a difference and some things don't. There have been some nice articles examining the various methods of washing and preparing the fat for grafting that show no significant difference between the methods. There are other articles that support one method or another. I don't think you can reasonably demand one method as best at this time. Remember, fat transfer is often a multiple stage procedure. A fair amount of what you inject gets resorbed, and this is different in different people. It is harder to be as accurate with the volume in fat grafting than it is with the volume in an implant augmentation. Get a consultation from a board certified plastic surgeon and talk over the specifics of your case. There are plenty of qualified surgeons in Atlanta.
