Positional plagiocephaly is a disorder in which the back or one side of an infant's head is flattened, caused by repeated pressure to one side of the back of the soft infant skull.
How is Plagiocephaly Prevented?
Changing Sleeping Conditions
Parents often face a conundrum: one should place a healthy sleeping baby on his or her back to reduce the risk of SIDS, but doing so may lead to plagiocephaly. Luckily, parents do not have to worry about either when their baby is sleeping in the supine position on a Lifenest. The physician-designed Lifenest Mattress Topper helps prevent plagiocephaly in several ways:

Lifenest's mattress topper cradles the babies head.

  • The Lifenest cradles the baby’s head, helping to prevent positional flattening.
  • The increased contact surface reduces the pressure per square inch on the head.
  • The Lifenest’s comfortable and supportive netting allows a baby’s head to move freely.
  • During supervised “Tummy Time,” the baby may breathe through the netting.

Flat Head Prevention Before Lifenest
  • Techniques for repositioning include supervised “Tummy Time,” switching the direction that your baby lies in the crib, and changing the location of the baby’s crib.
  • Talk to your health care provider about your baby’s head shape at each checkup.

Skull Distortion and Facial Asymetry

Deformational plagiocephaly produces an undesirable effect on a baby’s aesthetic appearance. Flat head syndrome not only lead to distortion of the skull shape, but sometimes also facial asymmetry, often with little hair growing in the flattened area. In severe plagiocephaly cases:

  • One eye appears larger than the other.
  • The ear on the flattened side is pushed forward more than the other side.
  • Eye alignment varies.
  • One cheek appears fuller than the other.
Neurodevelopmental Damage
  • Even though flat head syndrome was considered to be a purely aesthetic problem in the past, a recent case-control study led by Matthew L. Speltz, PhD at the Seattle Children Hospital, which included 235 infants with deformational plagiocephaly and 237 normal infants, found that the infants with plagiocephaly had significantly lower scores on neurodevelopmental tests.
Congenital Malformations
  • Congenital hip dysplasia, congenital scoliosis and congenital torticollis are all strongly associated with deformational plagiocephaly.

What causes Plagiocephaly?
The Naturally Soft Infant Skull
  • Typically, the average skull is one third longer than it is wide. Passage through the birth canal often makes a newborn's head appear pointy or elongated for a few days. Because infants' heads are soft to allow for the incredible brain growth that occurs in the first year of life, they're more susceptible to being "molded" into a flat shape.
  • Premature infants and infants who require placement in Newborn Intensive Care Units (NICU) are prone to positional plagiocephaly because their skulls are softer and they spend the majority of their time on their backs.

Supine Sleeping Position (Lying on Back)
  • Placing healthy young infants to sleep on their backs (for SIDS prevention) is associated with a 40% increase in deformational plagiocephaly.
  • As the infant spends more time in the supine position, or reclining with his or her head on a hard surface (such as in cribs, strollers, swings and playpens), the occiput is more likely to become deformed.
  • Positional plagiocephaly can also be developed before birth if the mother’s pelvis or a twin is exerting strenuous force on a baby. In fact, it is common to see plagiocephaly in multiple birth infants.

Observational Diagnosis
  • Most often, the diagnosis does not require X-rays or lab tests. A simple examination by a doctor is generally enough to make the diagnosis of positional plagiocephaly.
  • Positional plagiocephaly is generally easy for parents to notice. When looked at from above the baby’s head, one ear may appear more forward than the other. A "parallelogram" skull shape strongly suggests deformational plagiocephaly.
Extremely High Incidence
  • Over the past several years, pediatricians have seen an increase in the number of children with cranial asymmetry, particularly unilateral flattening of the back of the head (occiput). Currently, deformational plagiocephaly has reached epidemic proportions.
  • This increase is likely attributable to parents following the American Academy of Pediatrics "Back-to-Sleep" positioning recommendations aimed at decreasing the risk of SIDS (Sudden Infant Death Syndrome).
Custom Helmet or Band
  • More severe cases of positional plagiocephaly must be treated with a custom helmet or custom band that would need to be worn for 23 hours a day, for several months.
  • If you're starting late, your baby's skull may not become perfectly symmetrical..
