These days, we see a lot of babies wearing colorful helmets. That’s because they suffer from a flat head or some other condition that requires extra protection and a dynamic force on their skull. 
Plagiocephaly is becoming more common due to babies sleeping on their backs, which is a safe way to lay babies down because it protects them from Sudden Infant Death Syndrome (SIDS). 
In this article, we’ll discuss the flat head condition, its causative factors and treatments with a focus on orthotic treatment. 
Let’s dive right in. 
Overview of Plagiocephaly
Plagiocephaly is simply the flattening of a baby’s head. It usually goes away on its own as the bones develop and fuse to create a round shape. 
In severe cases, however, treatment is required. Plagiocephaly can happen to anyone if proper precautions are not taken, but it’s mostly reported in premature infants since their skull bones are much softer and pliable.  
1. Causes of Plagiocephaly
Plagiocephaly has various causes, which can be prenatal to postnatal but more times than not the actual cause of Plagiocephaly is unknown. 
Prenatal causes which lead to Plagiocephaly include a small uterus, twins or unusual pressure on the head during pregnancy although these lead to only mild Plagiocephaly. 
Other causes include sleeping in the same position [known as positional Plagiocephaly], muscular torticollis and craniosynostosis. 
2. Severity Levels of Plagiocephaly
Almost all babies have some level of asymmetry of the head when they’re born. And the bones align themselves as the skull matures. 
The severity of Plagiocephaly is determined by two scales; the Cranial Vault Asymmetry and the Cephalic Ratio.  The results help classify your baby’s Plagiocephaly in one of the three categories of mild, moderate and severe. 
When you visit the Orthotist for assessment, s/he measures the baby’s head to determine what kind of treatment, if any, is required to correct the skull shape.  
3. How’s Plagiocephaly Diagnosed?
The most prominent symptom of Plagiocephaly is flattening of the head from one side. It’s diagnosed based on the test performed by the Orthotist or a paediatrician. 
Other symptoms include facial asymmetry, mismatched ear levels, prominent blood vessels and palpable bony ridges around the flattening.
4. Plagiocephaly Treatment Options 
Oftentimes the Plagiocephaly will fix itself once your baby starts to lift his head and move around. 
Various treatments of Plagiocephaly include: 

  1. Turning the baby’s head regularly so that one part of the head doesn’t sustain too much pressure. 
  2. Following the home exercise program prescribed by the Pediatric Physical Therapist. These include stretching of the neck muscles, massaging the head and increasing tummy time during the day. 
  3. Cranial band or baby helmet therapy for the severe cases of Plagiocephaly. 
  4. Surgery to relieve the pressure on the growing brain and allow sutures to fuse in the correct alignment for a normal shaped head. 

What’s the Orthotic Treatment of Plagiocephaly? 
Orthotists are a part of the multi-disciplinary team of medical professionals who treat your child’s Plagiocephaly. From paediatricians to neurosurgeons and physical therapists, several team members decide on the best treatment approach for your baby based on the severity of the condition. 
The cranial band is the generally preferred orthotic treatment for this condition. 
But that’s not the only treatment. Babies aged less than 2 months old rarely ever need a cranial band. In their case, proper positioning and exercises are enough to correct the deformity. 
​1. How Does the Cranial Band Work? 
The cranial band is also known as the baby helmet and the cranial orthosis is made of a rigid thermoplastic material. It offers support to the growing skull while applying gentle pressure to the bones. 
Each cranial band is customized with an opening close to the flattened region. The main purpose of wearing the baby helmet is to realign the skull bones. 
2. How Long Does Your Baby Have to Wear the Cranial Band? 
The duration of wear depends on how early you start treatment. For babies aged less than 6 months, 12 weeks of wearing the cranial band is enough time to correct the Plagiocephaly. On average, the treatment lasts for three months. 
The time increases with an increase in the Plagiocephaly severity and the age of the baby. 
Your baby has to wear the helmet for 23 hours a day. 
3. How to Care For Your Baby and Their Helmet 
The good news is that the baby helmet is not uncomfortable for the kiddos. 
When your baby first starts wearing the cranial band, we recommend one hour off and one hour on. That helps babies get used to wearing it and also gives you an idea of how much your baby will sweat in the orthosis. 
You’ve to follow your Orthotist’s guidelines while cleaning the cranial orthosis and washing your baby’s head. And reach out to them in case your baby looks uncomfortable in it because that could mean that there’s an issue with the cranial band. 
Scientific Evidence for Effectiveness of Cranial Band Therapy  
There’s some controversy around the use of the cranial band for Plagiocephaly. But various researches have concluded that baby helmets are effective for reducing flat head deformity.
One study found that the effectiveness of the cranial band for Plagiocephaly increases if the treatment is started early, before 24 weeks of age. Here, researchers found that 83% of their sample had a positive result after using the cranial orthosis. 
Another research conducted on 18 months and older babies also concluded that the cranial band reduces the deformity if it’s worn for the prescribed duration. However, they also found that the treatment lasts for around 16 months when it’s started later in the baby’s life. 
Final Thoughts 
Plagiocephaly is a big word and scares most parents who’re hearing it for the first time. But the condition is much more treatable as you’ve read above.
