Study Notes
Revised Trauma Score (RTS)
- Composed of Glasgow Coma Scale, Systolic Blood Pressure, and Respiratory Rate.
Trauma and Injury Severity Score (TRISS)
- Comprised of Injury Severity Score (ISS), Revised Trauma Score (RTS), Age, and Mechanism of Injury (Blunt or Penetrating).
Mangled Extremity Severity Score (MESS)
- Considers:
- Energy of the injury
- Limb Ischemia
- Shock
- Age
Skull Base Fracture
- Anterior cranial fossa fracture is the most common, accounting for approximately 70% of cases.
- Middle cranial fossa fractures make up about 20%.
- Posterior cranial fossa fractures are the least common, representing about 5%.
- The frequency of skull base fractures is represented by the following: ACF > MCF > PCF.
- Anterior cranial fossa fractures are primarily associated with frontal bone involvement.
- Middle cranial fossa fractures often lead to temporal lobe contusion.
- Posterior cranial fossa injuries can result in occipital lobe contusion.
Regions of the Skull
- Anterior Fossa: 70%
- Central Skull Base: 25%
- Middle Fossa: 5%
- Posterior Fossa: 5%
