Slight plagiocephaly is routinely diagnosed at birth and may be the result of a restrictive intrauterine environment giving a "diamond" shaped head when seen from above.
If there is premature union of skull bones, this is more properly called craniosynostosis.

The incidence of plagiocephaly has increased dramatically since the advent of anti-sudden infant death syndrome recommendations for parents to keep their babies on their backs.

Data also suggest that the rates of plagiocephaly is higher among twins and multiple births, premature babies, babies who were positioned in the breech position or back-to-back, as well as babies born after a prolonged labour.
