Skull Fracture: Symptoms, Causes, and Treatment

Overview

A skull fracture is a break in one or more of the bones that form the skull. The skull consists of multiple bones that protect the brain from injury, and when these bones break, it can potentially lead to serious complications including brain damage. Skull fractures range from simple linear fractures that may heal on their own to complex fractures requiring immediate surgical intervention.

The severity of a skull fracture depends on several factors including the force of impact, the location of the fracture, and whether the fracture has damaged underlying brain tissue or blood vessels. While the skull is remarkably strong and designed to protect the brain, significant trauma can overcome this protection. Not all head injuries result in skull fractures, and conversely, not all skull fractures result in brain injury, though the two often occur together.

Skull fractures are classified into several types based on their pattern and severity. Linear fractures are the most common, appearing as thin lines without displacement of bone. Depressed fractures involve bone fragments being pushed inward toward the brain. Basilar fractures occur at the base of the skull and can be particularly dangerous due to their proximity to vital structures. Compound fractures involve a break in the skin, creating a direct path for infection to reach the brain. Each type requires different management approaches and carries different risks for complications.

Symptoms

Symptoms of skull fractures vary depending on the location, severity, and associated brain injury. Some symptoms appear immediately, while others may develop over hours or days.

Immediate Symptoms

Cervical spine immobilization
Glasgow Coma Scale (GCS) evaluation
Pupillary response testing
Vital signs monitoring

History Taking

Mechanism of injury details
Loss of consciousness duration
Witness accounts
Pre-injury symptoms or conditions
Medications (especially anticoagulants)
Previous head injuries

Physical Examination

Scalp inspection: Lacerations, swelling, depressions
Palpation: Step-offs, crepitus, tenderness
Otoscopic exam: Blood behind eardrum
Neurological exam: Complete assessment
Cranial nerve testing: All 12 nerves
Motor and sensory evaluation

Imaging Studies

CT Scan (Gold Standard)

Non-contrast head CT for all suspected fractures
Bone windows for detailed fracture visualization
3D reconstruction for surgical planning
CT angiography if vascular injury suspected

Other Imaging

X-rays: Limited use, may miss fractures
MRI: For associated brain injury assessment
Angiography: Vascular injury evaluation

Additional Tests

Beta-2 transferrin: Confirms CSF leak
Complete blood count: Baseline values
Coagulation studies: If on anticoagulants
Toxicology screen: If substance use suspected
Electrolytes: Metabolic assessment

Treatment Options

Treatment of skull fractures depends on the type, location, and severity of the fracture, as well as associated injuries.

Emergency Management

Stabilization: ABCs, spine immobilization
Intracranial pressure control: Head elevation, hyperventilation if needed
Seizure prevention: Prophylactic anticonvulsants
Pain management: Careful with sedatives
Prevent secondary injury: Maintain oxygenation, blood pressure

Conservative Management

For simple linear fractures without complications:

Observation in hospital for 24-48 hours
Serial neurological examinations
Pain management with acetaminophen
Activity restrictions
Avoid contact sports for 3-6 months
Follow-up imaging as needed

Surgical Treatment

Indications for Surgery

Frequently Asked Questions

How long does it take for a skull fracture to heal?

Simple linear skull fractures typically heal in 3-6 months. The bone will mend on its own, similar to other broken bones. However, recovery from associated brain injury or complications can take much longer, sometimes years, depending on severity.

Can you have a skull fracture without symptoms?

Yes, particularly with linear fractures. Some people may have minimal symptoms initially. However, this is why any significant head trauma requires medical evaluation - serious complications can develop hours or days after the injury, even if you feel fine initially.

What are the long-term effects of skull fractures?

Long-term effects depend on the severity and associated brain injury. Many people recover completely from simple fractures. Potential long-term effects include chronic headaches, seizures, cognitive changes, hearing loss, or neurological deficits. Regular follow-up helps monitor and manage any lasting effects.

When can I return to normal activities after a skull fracture?

Return to activities depends on fracture type and associated injuries. Generally, avoid contact sports for at least 3-6 months. Work return varies from weeks to months. Your doctor will provide specific guidelines based on your healing progress and type of activities.

Are skull fractures always visible on X-rays?

No, X-rays can miss many skull fractures, especially linear fractures or those at the skull base. CT scan is the gold standard for diagnosing skull fractures as it provides much better detail of bone and can also show associated brain injury.
