It might sound complicated, but plagiocephaly literally means "oblique head" (from Greek: plagio = oblique, and cephale = head). It's called a parallelogram deformity because if you look down on the infant's head (bird's-eye-view), this is the shape you will see.

From this angle, it looks as if half of the head has been pushed forward, often accompanied by misalignment of the ears, facial asymmetry and bulging forehead.

What does Plagiocephaly look like?

Here are examples of some of the varying degrees of plagiocephaly.
