Forms, monitoring … the point of the child’s fontanelle

With Dr. Cyril James, Pediatric Neurosurgeon

The baby’s skull is a field of permanent development after birth. Fontanelle is one of the essential ingredients for increasing cranial circumference! Concretely, what are baby fontanels? What are they for? What precautions should be taken? We stock up on this with Dr. Cyril James, Pediatric Neurosurgeon.

Definition: What is fontanelle in children? What is the difference between anterior and posterior fontanelles?

First, there are not one but two fontanels, as Dr. Cyril James explains: “The baby has two fontanels: anterior fontanelle and posterior fontanelle. There are stitches in the bones of the baby’s skull. At the junction of the three stitches, there is a flexible diamond-shaped membrane called the fontanelle. The frontal fontanelle, also called the large fontanelle, is located in front of the skull and is 3 to 6 centimeters wide. Conversely, the small fontanelle is located at the level of the occiput, i.e. behind the skull. It is about 1 cm wide and much less visible than its older sister.

Is fontanelle used for children?

The fontanelle is a soft area located at the junction of the skull bones. Its usefulness is crucial, as Dr. Cyril James explains: “Fontanels mainly play a role in two periods: birth and the first month of life. In fact, at birth, The baby’s skull is the largest organ in the mother’s womb. Fontanels will allow the baby’s head to be lowered to facilitate the baby’s entry into the mother’s vagina. This device allows the pregnancy to last up to nine months and does not expire before then. After birth, fontanels play a growth role. This allows fontanelles that are in flexible areas Rapid brain growth. It is considered that the latter experiences the fastest stage of its development in the first year of the child’s life.

At what age is the fontanel closed? How long can it last?

If these fontanels are important, they are not permanent in the baby’s head! Closing the fontanels is done in two stages, as explained by Dr. Cyril James in detail: “Closing the fontanels during brain growth is not the same as for the previous fontanelle and the posterior fontanelle. The fontanelle will close later.It is quite variable depending on the children, but it closes on average The baby is between 9 months and two years old

Fontanelle, what precautions should you take with a baby’s skull?

Needed for brain growth, baby fontanels can affect parents. These soft spots can even show blood clots in the scalp. Fragile in appearance, fontanels often worry parents who are afraid to hurt them. Do they need extra caution? Serial James gives us a negative answer: “ Fontanels are no more brittle than other parts of the baby’s skull. There are no special precautions to take. Of course, to avoid head trauma, these areas, like the rest of the skull, need to be protected from shock. ”

Swelling, drowning, dehydration … when to think about fontanelle? What’s the risk?

If there are no specific warnings about baby fontanels, it is important to monitor them, as this may indicate Nervous dysfunction In infants, by Dr. Cyril James in detail: “Observing fontanels will make it possible to follow the evolution of brain stress, but other possible disorders will also occur. Notice that the fontanels are constantly swollen, but this can lead to intracranial hypertension. In this case, it is important Make an appointment with a doctor as soon as possible. An intracranial ultrasound or MRI can then be done. The causes can be multiple: blood around the brain, tumors … e.g .: only a persistently swollen fontanelle. In fact, it can happen that the fontanels swell for a while when the baby cries, cries or defecates. “

It should be noted that fontanel tests are not sufficient to diagnose a possible neurological disorder in a child, recalls Dr. Cyril James: “It is also important to measure the circumference of the forehead, which is fundamental to determining the evolution of a child’s brain. . The pediatrician needs to measure the baby’s skull every month until he is one year old. “
