What Type Of Skull Fracture Can Result In Raccoon Eyes

Our current system is CNS – and so far we’ve covered introductory stuff (e.g., how do brain cells respond to injury), increased intracranial pressure, and congenital/developmental abnormalities. Now we’re moving on to CNS trauma, starting with skull fractures.

There are four main types of skull fractures, and you should know a few key things about each one (nicely summarized here).

1. Linear fracture

  • most common
  • straight crack
  • usually not serious

2. Diastatic

  • crosses one or more sutures
  • sutures widen in response to the fracture
  • usually occur in children

3. Depressed

  • bone displaced inward
  • comminuted (bone broken in many pieces)
  • may damage the underlying brain

4. Basal

  • Least common
  • May see CSF drainage from the nose, ear
  • May result in hematomas, especially in two areas: around the eyes and over the mastoid process.

Why would you get blood around the eyes or behind the ear with a basal skull fracture? Because blood can track from the site of the fracture to adjacent tissues. Here’s a little cartoon showing how this works, along with real-life examples.
