If a fontanel, the soft spot on a baby's skull, closes too quickly, a condition known as craniosynostosis may occur. This can restrict the growth of the skull and potentially lead to increased intracranial pressure, affecting brain development. Early diagnosis and intervention are crucial to address any associated complications and to ensure proper head shape and brain growth. Treatment often involves surgery to correct the shape of the skull and allow for normal brain development.

What are the four fontanels of an infant?
The four fontanels of an infant are the anterior fontanel, posterior fontanel, sphenoid fontanel, and mastoid fontanel. The anterior fontanel, located at the top of the head, is the largest and typically closes by 18-24 months. The posterior fontanel, situated at the back of the head, generally closes by 2-3 months. The sphenoid and mastoid fontanels are smaller and close within the first year of life.
What is the fate of a fontanel?
Fontanelle or Fontanel is the soft spot of an infant human skull between the cranial bones. The posterior fontanel closes on the first few months of life.
What is it fate in a fontanel?
"Fate" in the context of a fontanel refers to the future development and closure of the soft spots on an infant's skull, known as fontanels. These areas allow for brain growth and skull flexibility during childbirth. Typically, the anterior fontanel closes between 12 to 18 months of age, while the posterior fontanel usually closes by 2 to 3 months. The fate of a fontanel can indicate the health and development of a child, as abnormal closure patterns may suggest medical concerns.
Where is the posterior fontanel?
The posterior fontanel is located at the back of the head where the parietal and occipital bones meet in a newborn baby. It typically closes by the time the baby is 2 months old.
What fontanel closes last?
The fontanel that closes last is the anterior fontanel, also known as the soft spot on the top of a baby's head. It typically remains open until the child is about 18 to 24 months old, allowing for brain growth and development during that period. The closure timing can vary among individuals, but this is the general timeframe for most children.
When does the posterior fontanel close?
This one closes fairly early, usually by the time the baby is 2 months.
What fontanel between the parietal and occipital bone?
The fontanel located between the parietal and occipital bones is known as the posterior fontanel. It is a soft spot on an infant's skull that typically closes within the first few months after birth. This fontanel allows for flexibility during childbirth and accommodates the rapid growth of the brain during early development.
The fontanel between the parietal and occipital bones is the?
The fontanel between the parietal and occipital bones is the posterior fontanelle, also known as the lambda fontanelle. It is typically smaller and closes earlier than the anterior fontanelle.
What happens if an infants fontanel closes too early?
If an infant's fontanel (the soft spot on the skull) closes too early, a condition known as craniosynostosis may occur. This can restrict the growth of the skull and potentially lead to increased intracranial pressure, affecting brain development. Early diagnosis and intervention, often surgical, are crucial to prevent complications and ensure proper skull and brain growth. It's important for pediatricians to monitor head shape and development during routine check-ups.
When do babies fontanel close?
Babies have two main fontanels, the anterior and posterior. The posterior fontanel typically closes between 2 to 3 months of age, while the larger anterior fontanel usually closes by 18 months, although it can take up to 24 months for some children. These soft spots allow for the growth of the baby's brain and skull during early development. Regular pediatric check-ups help monitor their closure and overall development.
Is the coronal fontanel medial to the posterior fontanel?
The posterior fontanel would be in the back of the head. The coronal fontanel would be located in another part of the brain.
What are the names of the fontanels in fetal skull?
Anterior (frontal) Fontanel Posterior (occipital) Fontanel Anterolateral (sphenoid) Fontanel Posterolateral (mastoid) Fontanel
