When should a fontanel be assessed?
The time when the fontanel is too small to be measured by physical exam (and is considered closed) is extremely variable (Figure 4), but a small percentage of anterior fontanels of normal children are closed by age 3 months, 10% by 6 months, 25% to 50% by 12 months, and 98% to 100% are closed by 24 months.
What is normal fontanelle?
Fontanelles are the soft spots on an infant’s head where the bony plates that make up the skull have not yet come together. It is normal for infants to have these soft spots, which can be seen and felt on the top and back of the head. Fontanelles that are abnormally large may indicate a medical condition.

You may never be able to feel or see this one. The one on the top of the head remains present until your baby is between 7 and 19 months old. A baby’s soft spots should be relatively firm and curve ever so slightly inward. A soft spot with a noticeable inward curve is known as a sunken fontanel.
What examination should be performed on the newborn infant?
All parents are offered a thorough physical examination for their baby within 72 hours of giving birth. The examination includes screening tests to find out if your baby has any problems with their eyes, heart, hips and, in boys, testicles (testes).
Where is the bregma?
The bregma is the midline bony landmark where the coronal and sagittal sutures meet, between the frontal and two parietal bones. It is the anterior fontanelle in the neonate and closes in the second year 2 (typically around 18 months after birth).
What are the types of fontanelle?
The two primary fontanelles are the a nterior fontanelle and posterior fontanelle. The anterior fontanelle is found between the frontal bone and parietal bones. The posterior fontanelle is located between the pair of parietal bones and the occipital bone.
How do you perform a neonatal exam?
How is the newborn physical examination done?
- look into your baby’s eyes with a special torch to check how their eyes look and move.
- listen to your baby’s heart to check their heart sounds.
- examine their hips to check the joints.
- examine baby boys to see if their testicles have descended into the scrotum.

Why is Nipe performed?
NIPE screening examination The NHS newborn and infant physical examination ( NIPE ) programme’s main aims are to: identify and refer all children born with congenital abnormalities of the eyes, heart, hips and (in males) testes, where these are detectable, within 72 hours of birth.

Examination of the head includes inspection of the face, skin, hair, scalp and skull. Begin by observing facial features, understanding that they may vary by sex and race. Inspect the eyebrows, eyelids, palpebral fissures, nasolabial folds and mouth, noting any asymmetry.
What is the significance of the examination of the fontanelles?
Examination of the fontanelles provides evidence of altered intracranial pressure and, less commonly, is an index of the rate of development and ossification of the calvaria, which may be altered in a wide variety of disorders.
What is a fontanel?
A fontanel, also called fontanelle, is more commonly known as a soft spot. When a baby’s born, they typically have several fontanels where bones of their skull haven’t fused yet. A newborn has fontanels on the top, back, and sides of their head.

When is a cranial ultrasound used to assess the fontanel?
Depending on the age of the infant, a cranial ultrasound may be used to assess intracranial mass, hemorrhage or abnormal extra-axial fluid, and ventricular size. Although the size of the fontanel is variable, after age 4 months the reliability of this study decreases sharply.
