Plagiocephaly refers to an unusual or asymmetrical head shape. Positional plagiocephaly is flattening of one side of the back of the head related to either how the baby was lying in the womb or from them lying on the back of the head in the first months of life.

Basically, babies skulls are soft, and external pressure can cause flattening. It is a very common condition.  

It is estimated that 40-50% of all children have some degree of positional plagiocephaly and it forms the overwhelming majority of all cases referred to the Craniofacial service of the Sydney Children’s Hospitals ÐÇ¿ÕÌåÓý for assessment. 

While positional plagiocephaly is typically harmless and resolves on its own, lambdoid craniosynostosis, premature fusion of the lambdoid suture, can lead to serious complications if left untreated. Differentiating between these two conditions is crucial for ensuring appropriate management.

Simple measures, such as encouraging tummy time and varying sleeping positions can help facilitate normal head shape development. A consultation with a physiotherapist with an interest in paediatrics is useful to ensure that there are no issues with neck movement. 

Helmet therapy

Many parents are interested in helmet therapy for positional plagiocephaly. This is not available through the Children’s Hospital at Westmead, although there is a clinic at the Sydney Children’s Hospital at Randwick Campus for severe cases. 

Parents are also free to pursue helmet therapy privately. Private helmet providers can be found in all major cities and towns in Australia.
