• Temporal bone flaunts a complex anatomy with multiple osseous components. It houses various important neural and vascular structures along with the auditory apparatus. Trauma to the temporal bone poses a risk to all these structures. • Temporal bone fractures may present with hearing loss, balance dysfunction, CSF leaks, nerve palsies, life threatening vascular injuries etc. • Evolution of Multi-detector CT has revamped the imaging of temporal bone with fast imaging speed, better resolution, multi-planar reformations and hence improved detection ability. • Thus, it has now become mandatory for a radiologist to be well acquainted with the anatomy and imaging of temporal bone.  

• Anatomy of the temporal bone would be discussed in detail. • Imaging protocol with the normal CT anatomy would be illustrated with relevant images. • Various classification systems of the temporal bone fractures would be discussed with their clinical relevance. The types of fractures that would be discussed - o Longitudinal, transverse and mixed type of fractures o Fractures violating or sparing the otic capsule o Petrous or non-petrous fractures • Fracture mimics in temporal bone would be illustrated, to acquaint the radiologists with the possible false positives; like the intrinsic fissures, extrinsic fissures and the intrinsic channels.
