Penetrating brain injury is when an object enters the skull and harms the brain. It can hurt a small or large part of the brain. The injury is a threat to life. You will need emergency medical care.
|When a penetrating brain injury occurs, damage to the brain may occur in one area or a larger region.|

The injury may be from any object or outside force, such as:
- A fall, which could cause a piece of the skull to break off and enter the brain
- A motor vehicle accident
- A gunshot
- A stab wound
- A sports injury
- Abuse, such as being struck on the head with an object
This injury is more common in older adults because they may fall. It is also more common in younger adults due to the risk of motor vehicle accidents.
Other things that raise your risk are:

The doctor will examine you right away in the emergency room. This may mean checking:

The staff will first try to stabilize your health. If there is bleeding, steps will be taken to stop it right away. You may need surgery. To help with breathing, a tube may be placed down the throat and into the lungs. Also, fluids and blood will be given to keep your blood pressure stable.
A neurosurgeon may need to:
- Remove skull pieces that broke off—A bullet or other object may also need to be removed
- Remove part of the skull—The brain often swells after a severe injury. Removing a part of the skull gives it room to expand
- Make burr holes in the scalp and skull to drain clotting blood from a hematoma .
- Place a tube into the brain to drain fluid
The doctor may also put monitoring devices in the brain to check the:
- Pressure in the brain
- Temperature of the brain and the oxygen levels
Seizures may happen. The doctor may give you antiseizure medicines. Strong pain relievers, like opioids, may be given through an IV.
After your health has improved, the doctors will create a program that may mean working with:
- A physical therapist
- An occupational therapist
- A doctor who specializes in physical medicine and rehabilitation
- A neurologist
- A psychologist
The goal is to help you get back as much function as possible.
Here are ways to prevent this type of injury:

- Keeping guns unloaded and in a locked cabinet or safe
- Storing ammunition in a separate location that is also locked

- Using handrails when walking up and down stairs
- Using grab bars in the bathroom and placing non-slip mats in the bathroom

- Not drinking and driving or getting into a vehicle with someone who is under the influence of drugs or alcohol
- Obeying speed limits and other driving laws
- Using seatbelts and placing children in proper child safety seats
- Wearing a helmet when participating in certain sports and when riding on a motorcycle
