Temporal Bone Fracture Classification – Otic Sparing versus Otic Violating

Temporal bone fractures can be divided into:

  • Otic Sparing
  • Otic Violating
  • Otic Violating Fractures
    • 5 times more likely to have facial nerve injury
    • 8 times more likely to have CSF leak
    • 25 times more likely to have SNHL
    • No statistical difference in CHL between otic sparing versus otic violating
