What is Plagiocephaly?
Plagiocephaly 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 seems as if half of the head has been pushed forward, often accompanied by misalignment of the ears, facial asymmetry and bulging forehead.
