A newborn’s cephalic fontanel, generally referred to as the fontanel, typically closes between the ages of one and one and a half years.
Newborns’ fontanelles can be divided into anterior and posterior fontanelles, and the degree of closure of the cephalic fontanelle, or anterior fontanelle, reflects the degree of ossification of the baby’s skull. If the baby’s anterior fontanel closes too early, it may cause microcephaly; if the closure time is too late, such as more than two years old, it may indicate that the baby has rickets, hydrocephalus and other diseases.
After the birth of a newborn, the fontanel will gradually increase with the baby’s head circumference, to the baby’s six months, the fontanel began to appear ossification, gradually shrinking. The closure time of the fontanel is an important indicator of a baby’s brain development. Parents should try to avoid injuries to the baby’s fontanel in their daily care to prevent it from affecting his or her brain development.
If the closure time of the fontanel on the top of the head of a newborn baby is more than normal or less than normal, parents should pay attention to it and send it to the hospital for examination in a timely manner to make a clear diagnosis and carry out targeted treatment as soon as possible to prevent the disease from being delayed, which will affect the baby’s health.
