The nation's first full face transplant patient Dallas Wiens, right, poses for a photo with his wife Jamie Nash, left, and his guide dog "Charlie" after a news conference at McCormick Place in Chicago, Wednesday, Dec. 4, 2013. Despite still visible facial scars from the March 2011 surgery, Wiens looks and sounds like a recovered man. Medical imaging shows new blood vessel networks have formed, connecting transplanted skin with the patients' facial tissue, a finding that may help improve future face transplant surgeries, doctors announced Wednesday.
