A doctor at the prestigious Cleveland Clinic is ready to perform the world's first full facial transplant... just like she was two years ago. But no perfect candidate has appeared.

That's the word from CNN, which interviews Dr. Maria Siemionow, who hopes to take the next step after a partial face transplant was performed on a woman in France last year. (She's the one who was mauled by her dog and reportedly planned to keep smoking despite her new partial face.)
Why the wait? While she's gotten at least one call -- from a young person with acne who wanted a new face -- nobody has been just right yet:
I wonder how closely the federal witness protection people are watching the developments in facial transplants? There may be no better way to turn a somebody into a nobody.
Along these lines, there was a major book published a few years ago about the witness protection program. Anyone know if it touched on plastic surgery for relocated witnesses?
