What is Baby Flat Head Syndrome?

Baby flat head syndrome has become the most common, lay man’s term describing the condition known as Positional Plagiocephaly. From a parent’s perspective it has become accepted as the catch all phrase to define a baby’s head that is not symmetrical, it may be flat or it might be misshaped. In a sense it is misleading because not all the head shapes associated with the condition feature flat heads.

Below we have visualised the three main types of head shape that are associated with Baby Flat Head Syndrome. If you think your baby does have some sort of flat or misshaped head and you are concerned you can quickly and easily get our clinical opinion for free with our Baby Flat Head Syndrome diagnosis form.


Baby Flat Head Syndrome head shapes


Plagiocephaly Symptoms

 Loc Recreated Plagiocephaly Diagrams 04

Plagiocephaly is the word used to describe a diagonal asymmetry across the head shape.

  • Posterior flattening on one side
  • Anterior forehead flattening on the opposite side to posterior flattening
  • Anterior ear, forehead and eye orbit shift on same side of posterior flattening
  • Posterior bulge
  • Often associated with facial asymmetry


Brachycephaly Symptoms

Loc Recreated Plagiocephaly Diagrams 05

Brachycephaly, derived from the Greek, means short head, the shape of the skull is shorter than average. A brachycephalic skull is flat in the rear. The crown of the head towards the back is often high, the baby’s face may be wide and the ears can also protrude. .Brachycephaly is frequently position-related rather than congenital and can be seen in babies who have also been diagnosed with Plagiocephaly.

  • Bilateral occipital flattening
  • Increased width to length ration
  • Increased posterior head height
  • Bilateral frontal bulging

  • Bilateral bulging over the ears
  • Cupping of ears
  • Some degree of asymmetry (Plagiocephalic features)


Dolichocephaly/Scaphocephaly Symptoms

Scaphocephaly, also from the Greek, meaning ‘light boat’ head, to describe a head that is long and narrow resembling an inverted boat. This head shape is also referred to as Dolichocephaly. The head appears long and the forehead can protrude and become square shaped. It is more prevalent in babies that have spent time in neo-natal care.

Scaphocephaly can also be a type of cephalic disorder and is the most common of the craniosynostosis conditions accounting for about 50% of all such cases with a prevalence of 1in 2,000 live births. Craniosynostosis is the medical term for the premature closing of the suture that runs from front to back at the top of the head.

  • Decreased width to length ratio
  • Elongated, narrow head shape
  • Overall increase in head height
  • Bilateral frontal bossing

May also see:-

  • Some degree of asymmetry(Plagiocephalic features)


Treatment Options

If your baby has mild plagiocephaly, repositioning should be sufficient to help naturally resolve the issue. If your baby has moderate or severe plagiocephaly helmet therapy with the LOCband is proven to be very effective at normalising head shape.


Back to Sleep

Although the 'Back to Sleep' campaign has been linked to the increased incidence of positional plagiocephaly, (for more information, see the Diagnosis and Management of Positional Head Deformity) it has saved lives by reducing the incidence of Sudden Infant Death Syndrome (SIDS), (more information can be found on The Foundation for the Study of Infant Deaths). Therefore, babies should always be placed on their backs to sleep.
