What causes suture lines to widen abnormally?
What causes suture lines to widen abnormally?
This is the normal position. Diseases or conditions that cause an abnormal increase in the pressure within the head can cause the sutures to spread apart. These separated sutures can be a sign of pressure within the skull (increased intracranial pressure). Separated sutures may be associated with bulging fontanelles.
Why is my sagittal suture raised?
Ridging of the suture line can also occur when the bony plates fuse together too early. When this happens, growth along that suture line stops. Premature closure generally leads to an unusually shaped skull. Premature closing of the suture running the length of the skull (sagittal suture) produces a long, narrow head.
Is it normal to have overlapping sutures?
The borders where these plates come together are called sutures or suture lines. In an infant only a few minutes old, the pressure from delivery may compress the head. This makes the bony plates overlap at the sutures and creates a small ridge. This is normal in newborns.
What is bulging of the fontanelles indicate?
This is known as a bulging fontanel and may be a sign of brain swelling or fluid buildup in the brain. A bulging fontanel is an emergency. It can be a sign of pressure rising inside the skull which may result in damage to the baby’s developing brain.
What are suture lines in brain?
Cranial sutures are fibrous bands of tissue that connect the bones of the skull. The sutures or anatomical lines where the bony plates of the skull join together can be easily felt in the newborn infant.
What is a skull suture?
Cranial sutures are fibrous bands of tissue that connect the bones of the skull.
Why are there sutures of the skull?
Sutures allow the bones to move during the birth process. They act like an expansion joint. This allows the bone to enlarge evenly as the brain grows and the skull expands. One suture in the middle of the skull extends from the front of the head to the back.
