Temporal Bone Trauma

Temporal bone fractures represent roughly 20% of skull fractures. The initial evaluation of temporal bone trauma is exceedingly important as the presence or absence of facial nerve injury must be documented. If facial paralysis is present, it is critical to differentiate between immediate versus delayed onset facial paralysis. Delayed onset facial paralysis has a significantly better prognosis for recovery. The presence or absence of a cerebrospinal fluid leak must also be evaluated. Audiological evaluation is performed when the patient is stable.
