WHAT IS IT?
Positional Plagiocephaly (or Flat-Head Syndrome) is a term used to describe an asymmetry in the shape of the baby's head due to bone deformation. The baby's skull bones are soft at the time of birth. This allows their head to pass through the birth canal but also makes the bone susceptible to deformation. This is not to be confused with Craniosyntosis, which is also characterized with deformation of the skull, but caused by fusion of the bones of the skull rather than by external molding of the skull bones.
