Temporal bone fracture

Temporal bone fractures are mostly due to high-energy head trauma with high rates of concurrent intracranial and cervical spine injuries and belong to the wider spectrum of lateral skull base trauma.

Temporal bone fracture is thought to occur in ~20% (range 14-22%) of all calvarial fractures. They have a prevalence of 3% of all trauma patients in one series 1).

Given that the temporal bone represents the most complex bone structure in the human body, containing a multitude of vital neurovascular structures, variable clinical presentations may arise from such fractures, ranging from asymptomatic courses to serious consequences, such as conductive and/or sensorineural hearing loss, vascular and/or cranial nerve injury as well as cerebrospinal fluid leakage.

Isolated temporal bone fractures usually have a good outcome in children, but in some cases they can be fatal or have permanent sequelae. Long term follow up is recommended 2).
