Penetrating Brain Injury
(Brain Injury, Penetrating; Penetrating Wound to the Head; Wound to the Head, Penetrating)
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. It is a threat to life and needs emergency care.
Damage to the brain may be 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

The problems a person may have depend on what caused the injury and how severe it is. Some problems may be:

Treatment depends on:
- How severe the injury is
- The parts of the brain that were hurt
- The symptoms the person is having
Initial treatment involves lifesaving measures, such as stopping bleeding and providing help with breathing.
Surgery may be done to:
- Remove skull pieces that broke off
- Remove any objects, such as bullets
- Remove part of the skull to ease pressure from swelling
- Make holes in the scalp and skull to drain blood
- Place a tube into the brain to drain fluid
Medicine may be given to manage symptoms. Examples are:
- Antiseizure medicine
- Prescription pain medicine
Recovery will include rehabilitation, such as physical and occupational therapy.
Most penetrating brain injuries are due to accidents that cannot be prevented.
Healthy bones and muscles may help prevent injuries from falls. This may be done through diet and exercise.
