A fracture may encircle the skull, dividing it into two portions. With such a condition, one part of the skull can move on the other, producing mobility and sometimes crepitus. Fracture through the base of the skull allows escape of blood or cerebrospinal fluid from ears, nose, or mouth according to the region of fracture. In vault fractures, these materials may escape directly through scalp wounds. A large proportion of basal fractures result from linear fractures extending into the base, making them both vault and base fractures. Hemorrhage is extremely variable in quantity and duration; it can be severe for a few minutes or persist for days. The flow of cerebrospinal fluid usually persists for hours to days once leakage is established.
Unconsciousness is common in head injuries and obscures diagnostic symptoms. Fractures of the base are more uniformly accompanied by unconsciousness than vault fractures. Vomiting is also a common symptom, though not pathognomonic; it occurs in so many conditions that it's of little significance after the first few hours.
Headache follows all kinds of head injuries and can be mild or severe depending on the condition. Vertigo often accompanies injuries to the cerebellum or disturbances in end organs leading to it, causing symptoms when impulses are interfered with. General flaccidity including sphincteric relaxation is common in profound coma from head injuries.

Variations in temperature occur commonly, with simple concussion lowering body temperature while severe conditions like laceration raise it. Localizing symptoms such as deviations in eye positions, alterations in pupillary reactions, local paralyses, and disturbances in muscle tone may indicate the site of injury.
<Callout type="risk" title="Severe Risks">Severe head injuries can lead to profound unconsciousness, respiratory irregularities, and extreme temperature variations, posing significant risks.</Callout>
Disparity in deep reflexes is observed when paralysis exists following cortical injuries. Disturbances in higher psychic functions may occur with frontal lobe damage.

Organic lesions and functional disturbances in cranial nerves commonly accompany skull fractures.
Key Takeaways
- Unconsciousness is a common symptom of skull fractures, especially those involving the base of the skull.
- Vomiting and headache are frequent symptoms but not definitive indicators of skull fractures.
- Localizing symptoms such as eye deviations and pupillary reactions can help pinpoint the location of brain injury.
Practical Tips
- Monitor for unconsciousness and variations in pulse and blood pressure to diagnose potential skull fractures.
- Use diagnostic clues like eye deviations, pupil size changes, and muscle tone disturbances to identify specific areas of brain damage.
Warnings & Risks
- Severe head injuries can lead to profound unconsciousness and respiratory irregularities, posing significant risks.
- Extreme temperature variations may indicate severe conditions such as laceration or compression.
Modern Application
While the diagnostic methods described here are outdated, understanding these symptoms is crucial for recognizing potential skull fractures in emergency situations. Modern medical imaging techniques have improved diagnosis accuracy but knowing historical signs remains vital for initial triage and treatment.
Frequently Asked Questions
Q: What are common symptoms of a skull fracture?
Common symptoms include unconsciousness, vomiting, headache, vertigo, variations in pulse and blood pressure, and deviations in eye positions.
Q: How does unconsciousness relate to skull fractures?
Unconsciousness is more uniformly present with base fractures than vault fractures. It can range from momentary insensibility to profound coma depending on the severity of the injury.
Q: What are some diagnostic clues for identifying brain injuries?
Diagnostic clues include eye deviations, pupil size changes, and muscle tone disturbances that indicate specific areas of brain damage.
