Plastic surgeon Richard Hopper and his colleagues at Seattle Children's Hospital used a technique called Lefort II midface distraction and simultaneous zygomatic repositioning to realign the face of an 11-year-old boy with Apert syndrome, a rare genetic condition that causes bones in the skull to fuse prematurely. The procedure involves removing the entire front of the patient's face and using saws, chisels, plates and screws to reshape the eye sockets and lower forehead. The rechiseled face is then reattached to the skull, positioned so that bone will grow on the skull's side.
