Best answer: What causes a baby’s soft spot to close early?

Around two years of age, a child’s skull bones begin to join together because the sutures become bone. When this occurs, the suture is said to “close.” In a baby with craniosynostosis, one or more of the sutures closes too early. This can limit or slow the growth of the baby’s brain.

Can soft spot close early?

A condition in which the sutures close too early, called craniosynostosis, has been associated with early fontanelle closure. Craniosynostosis results in an abnormal head shape and problems with normal brain and skull growth. Premature closure of the sutures may also cause the pressure inside of the head to increase.

Is craniosynostosis serious?

If left untreated, craniosynostosis can lead to serious complications, including: Head deformity, possibly severe and permanent. Increased pressure on the brain. Seizures.

How do you fix craniosynostosis?

Your doctor may recommend a specially molded helmet to help reshape your baby’s head if the cranial sutures are open and the head shape is abnormal. In this situation, the molded helmet can assist your baby’s brain growth and correct the shape of the skull. However, for most babies, surgery is the primary treatment.

What causes craniosynostosis during pregnancy?

Symptoms and Causes

Sometimes, craniosynostosis occurs because of a sporadic (random) gene mutation (change), or it may run in families. Prematurity is a risk factor for craniosynostosis. In other cases, some factors during pregnancy increase a baby’s risk for developing craniosynostosis.

When do babies soft spots close?

These soft spots are spaces between the bones of the skull where bone formation isn’t complete. This allows the skull to be molded during birth. The smaller spot at the back usually closes by age 2 to 3 months. The larger spot toward the front often closes around age 18 months.

At what age does the fontanelle close?

The posterior fontanelle usually closes by age 1 or 2 months. It may already be closed at birth. The anterior fontanelle usually closes sometime between 9 months and 18 months. The sutures and fontanelles are needed for the infant’s brain growth and development.

Can craniosynostosis correct itself?

The mildest forms of craniosynostosis do not require treatment. These cases manifest as mild ridging without significant deformity. Most cases, however, do require surgical management.

What happens if craniosynostosis is left untreated?

Left untreated, craniosynostosis can result in further cranial deformity and potentially an overall restriction in head growth, with secondary increased intracranial pressure. It can also lead to psychosocial issues as the child interacts with peers during development.

When do you know if your baby has craniosynostosis?

Craniosynostosis Symptoms

In infants with this condition, the most common signs are changes in the shape of the head and face. One side of your child’s face may look markedly different from the other side. Other, much less common signs may include: A full or bulging fontanelle (soft spot located on the top of the head)

At what age is craniosynostosis surgery done?

Most procedures for the treatment of craniosynostosis are performed before the age of one year, and some are performed before 3-4 months of age. Almost any child with a fused suture is a candidate for surgery.

Does craniosynostosis hurt?

In general, craniosynostosis is not a painful condition. However, if there is increased pressure on the brain, it can cause: Abnormalities affecting the face and hands. Headaches.

Does mild craniosynostosis need surgery?

A small number of babies with mild craniosynostosis won’t need surgical treatment. Rather, they can wear a special helmet to fix the shape of their skull as their brain grows. Most babies with this condition will need surgery to correct the shape of their head and relieve pressure on their brain.

Does craniosynostosis run in families?

Craniosynostosis is often noticeable at birth, but can also be diagnosed in older children. This condition sometimes runs in families, but most often it occurs randomly.

Can craniosynostosis cause autism?

An extrinsic component of an organic brain disorder has also been implicated in ASD development [3]. Craniosynostosis is associated with a chronic elevation of intracranial pressure (ICP), and the associated developmental disturbance in the brain has been implicated in the development of ASD [4–6].

Is craniosynostosis genetic?

In extremely rare cases, primary isolated craniosynostosis is genetic and in such cases is usually inherited as an autosomal dominant trait. Most cases of primary craniosynostosis that occur as part of a syndrome are also inherited as autosomal dominant traits.
