The Temporal Bone

  • Raymond F. Carmody
Chapter

Abstract

The complex, intricate anatomy of the temporal bone makes this area one of the most difficult to master in all of neuroradiology. Moreover, the small size of many of the structures of clinical interest taxes the spatial resolution of our current generation of computed tomography (CT) and magnetic resonance imaging (MRI) scanners. While CT is the procedure of choice for imaging the bony structures in this region, MR is better for soft tissue detail (Table 29.1a). Pluridirectional tomography, once the mainstay of temporal bone imaging, is less satisfactory and is seldom used today.1–5 Plain-film radiographs have been relegated to assessing mastoid pneumatization and the position and integrity of cochlear implants.6–7 Once one has learned the radiographic anatomy of the temporal bone, recognizing pathologic changes is less difficult, because the anatomy of this area is remarkably constant.
