Background
Temporal bone fractures often result from high-impact blunt trauma such as motor vehicle accidents or falls.
The anatomy of the temporal bone is complex, with numerous structures within and adjacent to it. The vestibular apparatus and cochlea, which are responsible for hearing and balance are within the petrous portion of the temporal bone. Other structures include major vessels such as the internal carotid artery, jugular bulb, sigmoid sinus, and cranial nerves.
Injury to these structures can lead to various secondary complications. It is vital therefore, to have a sound understanding of normal anatomy and the complications that arise from temporal bone trauma.
