Facial Plastic Surgeon (ENT) vs. Craniofacial Surgeon (Plastics)

What is the difference in their practices (surgeries they perform, population they service, private vs. academic split)? Can Plastic surgeons become Facial Plastic certified, and can ENT surgeons become Craniofacial certified? If you are one, or are trying to become one, why did you pick one or the other?
