Lipo: Dermatologist Vs. Plastic Surgeon

If only this impression suggested by the surgeons responding to you question were true. There is absolutely no data to say that one speciality does better liposuction surgery than another speciality. In the USA, the specialities of dermatology and plastic surgery account for the vast majority of liposuction performed.
What is undisputed is that general plastic surgeons account for a disproprotionate number of operative deaths related to liposuction. General plastic surgeons are much more likely than dermatologists to get sued for liposuction malpractice. This does not mean that general plastic surgeons are less competent than dermatologist in performing liposuction. However, general plastic surgeons are more likely to perform surgery under general anesthesia than dermatologists and this does appear to increase the risk of death from a liposuction procedure. The risk may be as high as 10 times as great.
So if all you need is body sculpting, you have a pretty clear choice provided you are a good candidate to have liposuction under local anesthesia. Dr. Klein would be an excellent choice as would be any of his associates.
However, if your issues are more, such as a weakness in your abdominal wall following pregnancy, a known hernia, history of profound weight loss with hanging skin, then these are conditions that are best addressed by a general plastic surgeon.

Liposuction is a surgical procedure. It is performed under sedation anesthesia, at minimum and, in NY, non-surgeons do not have privileges to perform such procedures in licensed facilities. Similarly, surgeons are trained to handle complications of surgery. I take exception to the notion that plastic surgeons are responsible for more deaths as an indictment of our skills. We handle major surgeries as opposed to more minimal procedures. Additionally, the anesthesiologist performs the sedation and I know few anesthesiologists who would administer sedation for a dermatologist. Board certified plastic surgeons have at least six years of residency training devoted solely to surgery as opposed to internists who hang out a shingle, call themselves experts in cosmetic procedures because they are lucrative and place patients at risk. Given your situation, you will need someone with expertise in surgical revision and, unfortunately, will require further surgery, pain and expense to address the consequences.

There are many thing that could constitute a bad result following liposuction. The solution may be more liposuction, fat transfer, or dermatolipectomies. The point is to make the most of a bad situation. Spend time with various doctors. Understand the options. A complete solution may be neither quick nor cheap. Remember the axiom "when all you have is a hammer, all the world looks like a nail"
