Several injuries and health conditions can impact your cranial bones, including fractures and congenital conditions.

Fracture

A fracture refers to any type of break in a bone. There are several types of skull fracture that can affect cranial bones, such as:

Depressed. This refers to a fracture that makes part of your skull appear sunken.
Linear. A linear fracture in a cranial bone means there’s a break in the bone, but the bone itself hasn’t moved.
Basilar. This type involves a break in one of the bones near the base of your skull, such as the sphenoid bone. This is a serious condition requiring immediate treatment.
Diastatic. A diastatic fracture occurs along one of the sutures of your skull, making it wider than usual. It’s usually seen in infants.

In many cases, skull fractures aren’t as painful as they sound, and they often heal on their own without surgery. However, more severe fractures may require surgery.

Craniosynostosis

Some infants are born with a condition called craniosynostosis, which involves the premature closing of skull sutures. This leads to an unusually shaped skull and can sometimes affect facial features.

There are several types of craniosynostosis, depending on the sutures they affect:

Bicoronal synostosis. Infants with this type may have a flattened and elevated forehead.
Coronal synostosis. This type can cause flattening on one side of the forehead and impact the shape of the eye socket and nose.
Lambdoid synostosis. This can lead to flattening on one side of the back of the skull. It can also affect the positioning of the ear or cause the skull to tilt sideways.
Metopic synostosis. This can cause a triangle-shaped skull or pointed forehead. It can also make the eyes appear closer together.
Sagittal synostosis. This type may cause the forehead to bulge out. The area around the temples might also appear very narrow, making the head look elongated.

Craniosynostosis requires surgical treatment to avoid later complications.

Other conditions

Some other conditions that can affect the cranial bones include:

Cleidocranial dysplasia. Mutations to a specific gene cause unusual development of the teeth and bones, including the cranial bones. Common symptoms include a sloped forehead, extra bone within skull sutures, and an enlarged skull.
Craniometaphyseal dysplasia. This is an inherited condition that causes thickening of the cranial bones, which can lead to a protruding forehead and wide-set eyes.
Paget’s disease of bone. New bone tissue is rapidly made due to unusual behavior of osteoclasts, which are a type of bone cell. People with this condition are more prone to fractures because the affected bone is usually weaker.
Fibrous dysplasia. This causes the development of scarlike tissue instead of bone tissue due to a mutation in bone-producing cells. It tends to only affect a single bone at a time, though more may be involved in some cases.
Osteomas. An osteoma is a benign overgrowth of bone on the skull. People with osteomas typically have no symptoms. However, if the growth puts pressure on a nerve, it can cause hearing and vision problems. These usually resolve once the growth is removed.
