Computed tomography of the temporal bone

Computerized tomography (CT) is useful in otolaryngology, particularly in those patients with pathology of the posterior fossa and skull base. With the current development and improvement of CT scanners, the more detailed anatomy of the temporal bone can now be evaluated. For interpretation, detailed knowledge of the temporal bone and skull base anatomy is essential. The methodology of CT scanning of the temporal bone is presented along with a detailed description of the anatomy both in the axial and the coronal projections. A review of the current CT literature on the temporal bone is with discussion of the advantages and limitations of this diagnostic tool.
