The result is a symmetrically shaped head. Some sutures extend to the forehead, while others extend to the sides and back of the skull. One suture in the middle of the skull extends from the front of the head to the back. The major sutures of the skull include the following:. Metopic suture. This extends from the top of the head down the middle of the forehead, toward the nose. The 2 frontal bone plates meet at the metopic suture.
Coronal suture. This extends from ear to ear. Each frontal bone plate meets with a parietal bone plate at the coronal suture. Sagittal suture. Skip to main content. Certainty Style Key. Certainty styling is being phased out topic by topic. Hover over keys for definitions:.

I am sorry not to be able to help. Just thought you would like to know that helmet treatement is available on the NHS at Frenchay hospital see post below :. Thank you very much for your email. N passed your message on to me as I am one of the paediatric consultants in the department.
I would also ask you to consider the other posibilities of Craniosynostosis such as Lambdoid Suture where the head measures greater than 12mm particularly if the Mother is:. As all of the above greatly increase the risk of some form of Craniosynostosis and Fluoxetine has been identified in causing other birth defects such as heart and lung problems in babies…. Very useful concise advice — still trying to reassure parent. Is there any update on helmets?
One of my colleagues here has a bit of an interest in plagiocephaly. I will ask him if there is any relevant recent research. It seems they get better anyway. Helmets are not mentioned in this paper. My colleague says that some neurosurgeons use them in children with craniosynostosis but that they are probably not required for simple positional plagiocephaly. The problem arises early, once a preference for lying on one side is demonstrated.
Positional Plagiocephaly will remodel spontaneously if the baby is positioned differently — as already indicated below. I cannot give a percentage figure as none currently exists. But, taking care over re-positioning the child certainly does work.
Also of note, despite running our craniofacial clinic in Leeds for 15 years, we have not had older children referred with ongoing positional plagiocephaly. As far as moulding helmets are concerned, there is no randomised control trial evidence to prove efficacy. They are available from a variety of sources privately, many of whom do a number of measurements and scans to demonstrate a before and after. There is an argument that going for a helmet will help adjust for a sleeping preference and allow the natural remodelling to occur but their efficacy is not proven.
So, in short, our normal advice is that positional plagiocephaly will self-correct if care is taken over positioning the baby, and we do not recommend helmets. Plagiocephaly an asymmetric head shape has multiple causes. Different from the cranial moulding associated with childbirth, which usually resolves spontaneously in the first weeks of life. Management of positional plagiocephaly is advise: Positioning.
