Although all plastic surgeons are trained in aesthetic surgery, some plastic surgeons have dedicated themselves to additional specialized training in a particular area of plastic surgery. Aesthetic (cosmetic) plastic surgery is a discipline within plastic surgery that specializes in cosmetic operations and procedures of the face, breasts, and body, such as breast augmentation and tummy tuck surgery. A fellowship in aesthetic surgery provides additional training in the subtle, but essential, nuances of analysis, planning, and judgment for cosmetic surgery. In addition, aesthetic fellowships are often directed by world renowned surgeons offering a unique opportunity to "learn from the very best."
