Does every bump on the head need a CT scan?
No. Doctors use validated, age-adjusted decision tools to identify who is genuinely at risk for a fracture or brain injury and who can be safely watched without any imaging at all. Most head bumps in otherwise well-appearing people, adults and children alike, don't need a scan.
Does a skull fracture always mean brain damage?
No. The skull and the brain underneath it can be injured independently of each other. Many skull fractures are found with a completely normal brain underneath, and, separately, a person can have a significant brain injury with no fracture at all.
Can a skull fracture heal on its own?
Yes, and most do. The large majority of skull fractures are simple linear fractures, which remodel and disappear on their own over a period of months, with no surgery, casting, or other intervention needed.
What is a growing skull fracture, and how would I know if my child has one?
It's a rare complication, seen almost only in children under 3, in which a small tear in the tissue lining the skull doesn't heal along with the bone. Over weeks to months, brain tissue and fluid slowly push through the widening gap, producing a soft bump at the old fracture site that keeps growing instead of shrinking. Any enlarging or newly appearing bump at a prior fracture site in a young child should be evaluated.
Is a cephalohematoma the same thing as a skull fracture?
No. A cephalohematoma is a pocket of blood between the skull bone and its covering tissue, common after a difficult delivery, and it is not itself a fracture. However, about one in four infants with a cephalohematoma also has a fracture underneath it, which is why this finding often prompts imaging in a newborn.
My infant has a dent in their skull. Will they need surgery?
Not necessarily. A smooth, rounded dent with no true fracture line, sometimes called a "ping-pong" fracture, is unique to infants, whose skull bone is pliable enough to bend without breaking. Many resolve on their own as the infant grows; others are corrected at the bedside with a vacuum-assisted technique, and only some require surgery.
How long until the bone is fully healed?
Most linear fractures in young children remodel within 3 to 6 months. Healing is more gradual in older children and adults, though the timeline matters far less than the absence of any of the warning signs described above.
Can a skull fracture cause seizures?
A seizure after a head injury is more closely tied to injury of the brain itself, such as bleeding or bruising, than to the fracture in the bone. That said, any seizure after a head injury needs emergency evaluation, regardless of the cause.
Will there be a permanent dent or bump afterward?
Usually not. Simple linear fractures typically remodel back to a normal contour. A depressed fracture that's surgically elevated is restored to its normal shape at the time of surgery. A growing fracture, once repaired, also restores a stable skull contour, though it requires the two-stage repair described in the treatment section above.
Do I need to see a neurosurgeon for every skull fracture?
Not always; many are managed by emergency medicine and pediatric or trauma teams without any neurosurgical involvement, especially simple linear fractures with a normal neurologic exam. Neurosurgery becomes involved specifically for depressed fractures being considered for elevation, any fracture with an associated bleed, a suspected or confirmed dural tear, or a growing fracture.
