A US man named Derek Pfaff successfully underwent a 50-hour face transplant involving 80 healthcare professionals at Mayo Clinic. Pfaff, who lost his face 10 years ago in a suicide attempt, was unable to eat solid food or speak despite undergoing 58 reconstructive surgeries. About 85% of Pfaff's face was reconstructed and replaced with donor tissue during the transplant.
