Positional Plagiocephaly Program
What is positional plagiocephaly?
It typically appears before an infant is 20 weeks old and can dramatically affect the shape of a baby’s head. Also known as deformational plagiocephaly or flat head syndrome, it is caused by the baby being in the same position for an extended amount of time (a crib, car seat carrier, swing).
Sometimes, this condition can be noticed while carrying the baby, the head may feel like it has an irregular shape/ asymmetry. A bald spot may also appear in the area where the infant prefers to rest his or her head. Also, the hair in the area might not lie flat, with hair strands extending outward instead of lying smoothly against the head. When asymmetry is mild to moderate, changes in sleep positioning and activities may help to improve the skull shape without the need for further intervention. Infants with more severe cranial asymmetry may have a chance for improvement and benefit from cranial molding with helmet therapy.
Since 1996, the American Academy of Pediatrics (AAP) recommends that babies sleep on their back to reduce the risk of Sudden Infant Death Syndrome (SIDS). Parents are encouraged to always check with their pediatrician first for guidance.
It is recommended that all infants with cranial asymmetry be properly evaluated by a pediatric specialist to rule out craniosynostosis. Unlike positional plagiocephaly, craniosynostosis requires surgery and can be diagnosed by X-ray.
What are the signs of positional plagiocephaly?
- Ipsilateral frontal bossing
- Anterior displacement of ear on affected side
- Flattened occiput on affected side
