Skull base fractures and their complications.

Basilar skull fractures are a relatively frequent occurrence in significant head trauma, and their detection is important, as even linear nondisplaced fractures can be associated with critical complications. The management of skull base fractures depends on the location and extent of these associated complications. This article reviews skull base anatomy; morphology of the common fracture patterns within the anterior, central, and posterior skull base; associated complications; imaging findings; and possible pitfalls in imaging of skull base trauma.
