Plagiocephaly is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull. It is also referred to as "Flat head Syndrome".
Plagiocephaly is the term that is used to describe a diagonal asymmetry across the head shape (see pic 1).
This term particularly describes a flattening to one side at the back of the head; this often causes some facial asymmetry (see pic-2).
In the moderate to severe cases, there may be:
Variations in the eyes alignment, One eye appears larger than the other
Ear displacement: The ear on the affected side may be pushed further forwards the front of the head compared to the other side.
One cheek appears fuller than the other.
The forehead on the affected side becomes more prominent.
The syndrome is widely seen among new born babies as they are often unable to turn their head in one direction due to neck pain. This causes the baby to prefer to be positioned on the same side of the skull. Constant pressure causes a flattening of the soft tissues on one spot compared to the rest of the babies skull.
