The majority of breast augmentations done in the US are done under general anesthesia, where you are completely asleep. The type of anesthesia is not as important as who is doing the anesthesia for your procedure. You want to make sure that a board certified anesthesiologist is doing your anesthesia whether it is sedation or general. Many times a certified registered nurse anesthetist will be assisting your anesthesiologist in performing your anesthesia.
I personally do all of my breast augmentations under general anesthesia. This is my method of choice as the majority of implants are placed below the muscle. When the patient is under general anesthesia, the muscle will be relaxed, making the surgery easier and more precise. It is also much simpler for the patient.
