Legend axial CT images through the skull base show multiple fractures involving the basisphenoid, sphenoid sinus and left temporal bone. The temporal bone fracture is longitudinal in orientation.

Legend Fractures also involve the R lessor wing of the sphenoid, the planum sphenoidale, and squamosal portion of temporal bone. The ethmoid and sphenoid sinuses are partially opacified.

Legend High resolution thin sections through the left temporal bone show the longitudinal fracture extending into the mesotympanum, which is opacified. The malleus and incus are intact. The fracture traverses near the geniculate ganglion and genu of the facial nerve.

Legend The fracture extends through the mastoid air cells and may involve the tegmen. The incudomalleolar joint is widened, indicating subluxation of the ossicles. Key words: temporal bone orbit trauma
