Skull (lateral view)

Last revised by Amanda Er on 31 Mar 2023

The skull lateral view is a non-angled lateral radiograph of the skull. This view provides an overview of the entire skull rather than attempting to highlight any one region.

This projection is used to evaluate for skull fractures, in addition to neoplastic changes and Paget disease. In the trauma setting, a horizontal beam lateral projection may demonstrate air-fluid levels in the sphenoid sinus 1, an indication of basal skull fracture.
