How to detect plagiocephaly?

This page will help you detect and assess if your baby has plagiocephaly , brachycephaly or scaphocephaly . In case of doubt, it is always advisable to contact your pediatrician, or our team directly.

You may have noticed at bath time as you passed a mirror, or perhaps someone commented on the shape of your baby’s head. Unfortunately, skull deformities are not uncommon nowadays. According to According to Aliyah Mawji, RN, of the Canadian Pediatric Society, in her article The incidence of positional plagiocephaly: a cohort study ,“The incidence of plagiocephaly in infants aged 7 to 12 weeks has been estimated at 46. 6%. Of the total number of infants with plagiocephaly, 63.2 % were affected on the right side and 78.3 % had a mild form. “

Undoubtedly, an abnormal head shape raises many questions, the first of which is a common one, “Am I really seeing what I think I am seeing?”

A diagnosis of plagiocephaly looks very different from one baby to another, no two cases are the same. It can guide you ( by way of guidance ) through evaluating your baby’s head shape from five different points of view , helping you better understand your child’s condition and choose the right treatment for him or her.

The information provided in this page is indicative and is not intended to replace an evaluation by a medical professional .We recommend you visiting your paediatrician for a confirmed diagnosis. We invite you to speak directly with one of our expert doctors by scheduling an evaluation.

I. From above

To start, have someone hold your baby in your lap while you stand and look at the top of your baby’s head. From this point of view, what is the general shape of your baby’s head? Normally, the head is about 1/3 as long as it is wide. In flat head syndrome, the head may appear flat on one side, wide at the back, or long and narrow.

Below we have provided examples of abnormal head shapes you may see. Keep in mind that you may not see these forms exactly: variations ranging from mild to moderate to severe and even combinations of these forms may occur.

III. Ear Alignment

By looking at the alignment of your baby’s ears from above, you can determine the severity of the condition.

While holding your baby on your own lap this time, gently place an index finger in each of their ears. How are your fingers aligned? A more noticeable misalignment indicates a more severe condition.

It is especially important to note what you see here. While plagiocephaly is a highly treatable condition, research has shown that the best results are achieved when treatment begins early. Because cranial cap therapy is effective for a short period of time and severe cases of plagiocephaly are more complex to correct, it is crucial that infants with advanced forms of the condition begin treatment as soon as possible.

IV. Front View

Next, we will look at the symmetry of your baby’s face. Since you see your baby’s face every day, the best way to spot the differences between the right and left sides is to hold your baby in front of a mirror and look at his or her reflection. How level are the eyes and the top of the head? Is one cheek fuller than the other? How big is the head in relation to the face ? Examples of what to look for are provided below.
