It's not to say that these other doctors can't perform cosmetic procedures well. Many of them do. And if you had five friends who went to a particular doctor who wasn't a plastic surgeon and had excellent results by all means go to that doctor. But all things being equal you want to go to someone who will give you the best chance at having a great result. And this in my opinion is a plastic surgeon who specializes in cosmetic surgery.
Plastic surgery is the one truly artistic field in the field of surgery.
To be able to visualize objects in three dimensions is key to a successful procedure. I believe it is my artistic skills which allows me to achieve excellent results.
