What causes the fontanelle to 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.
What is premature closure of anterior fontanelle?
SMALL FONTANEL OR EARLY FONTANEL CLOSURE Craniosynostosis is the premature closing of one or more cranial sutures, resulting in an abnormal head shape. The condition can be idiopathic or caused by hyperthyroidism, hypophosphatasia, rickets, or hyperparathyroidism.
What is the Fontanel commonly called?

What is fontanelle closure?
Closure. In humans, the sequence of fontanelle closure is as follows: The posterior fontanelle generally closes 2 to 3 months after birth; The mastoid fontanelle closes next from 6 to 18 months after birth; and. The anterior fontanelle is generally the last to close between 12 and 18 months.
How do you fix craniosynostosis?
One treatment method your doctor may recommend is traditional open surgery, referred to as cranial vault remodeling. Cranial vault remodeling: This is the surgical approach that doctors have relied on for decades to treat craniosynostosis. This is typically performed for babies 5-6 months of age or older.
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.
When do the Fontanels 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.
When does the mastoid fontanelle close?
The mastoid fontanelle, a paired structure, can be found at the intersection of temporal, parietal, and occipital bones. Additionally, the mastoid fontanelle also has the name of the posterolateral fontanelle. These fontanelles may close anywhere from six to eighteen months of age.
At what age is craniosynostosis usually diagnosed?
