Types of skull fracture

There are 4 types of skull fractures in adults that range from mild to severe:

• Linear skull fracture. This is a break in the bone, but the bone does not move out of place.

• Depressed skull fracture. Part of the skull bone is sunken in from the injury. In many cases, this needs treatment with surgery.

• Skull base fracture. This is a break in the bone at the bottom of the skull. It can be a serious type of skull fracture. You may have bruises around your eyes and a bruise behind your ear that appear 1 to 3 days later. You may also have CSF draining from your nose or ears. This is because of a tear in part of the covering of the brain. This type of break often needs surgery right away.

• Penetrating skull fracture. This is a break from something going through the bone, such as a bullet, blade, or blast fragments. This often causes severe injury and bleeding in the brain. It needs treatment right away with surgery.

Diagnosing a skull fracture

The healthcare provider will ask about your health history and symptoms. Tell the healthcare provider if you are taking medicine to thin your blood, such as warfarin. They will ask about recent accidents or injury and give you a physical exam. You may also have tests, such as:

• CT scan. This test uses a series of X-rays and a computer to create detailed images of the body. This test can show broken bones, blood, and injuries to the brain.

• MRI. This test uses large magnets, radio signals, and a computer to create images of tissues in the body.

• X-ray. This test uses a small amount of radiation to create images of bones and other parts of the body.

• Blood tests. These are done to check for signs of infection and other problems.

Treatment for skull fracture

Treatment depends on how severe the injury is. A more serious injury may mean you need surgery right away. Your healthcare team will talk with you about surgery if you need it. 

Or you may be watched for a few hours in the hospital and then go home. You’ll need to rest and follow instructions about self-care. You’ll need to watch carefully for new symptoms (see below). You may also be given medicine to help prevent infection, tetanus, or seizures. Your healthcare provider will tell you more if you need medicines.
