Pfeiffer syndrome is a condition in which certain sutures are fused prematurely. There is a high forehead, and the top of the head may appear pointed. The middle face appears flattened, the nose is small and has a flattened appearance, eyes are widely spaced, and the upper jaw is underdeveloped, which causes the lower jaw to appear prominent. The thumbs and big toes have a broad appearance and teeth are often crowded.
