Plagiocephaly, commonly known as Flat Head Syndrome, is a condition that causes a flattened appearance in a baby’s head or face. Plagiocephaly can also be called deformational plagiocephaly or positional plagiocephaly. The term plagiocephaly is taken from the Greek plagio meaning “oblique” and cephale meaning “head.”
Plagiocephaly is characterized by a parallelogram-type appearance of the baby’s skull; that is, if you look at your baby’s skull from a bird’s eye view, you’ll see that one side or the back of the head is flattened, while the other side appears more rounded. The eyes may appear asymmetrical, one cheek may appear “fuller” than the other, and one ear may appear to be more forward than the other.
