Petrous bone fractures are fractures of the Os temporale.
Classification
Petrous bone fractures are classified as longitudinal or transverse fractures, also referred to as longitudinal petrous bone fractures and transverse petrous bone fractures, respectively.
Etiology
Longitudinal fractures are by far the more common type, accounting for approximately 70-90 % of post-traumatic fractures. Transverse petrous bone fractures are significantly less common, but are frequently associated with deficits involving the Facial nerve or Vestibulocochlear nerve[^1].
