Abstract
Today, the anatomy of the temporal bone can be evaluated in detail. Computed tomography (CT) is the method of choice for examining the external and middle ear. However, CT also provides a great deal of information about the inner ear. The most recent high-end CT systems, using helical scanning and multidetector technology, enable scanning of the temporal bone in detail. Images with a spatial resolution of 230 μm can be acquired on these systems, and these images can be reformatted so that they overlap every 0.1 mm. On these very thin images, partial volume is no longer a problem, and small structure can therefore be seen. Moreover, excellent multiplanar reconstructions (MPRs) can be made. Temporal-bone imaging is now also possible with high-end cone-beam (CB) CT systems, which allow images with a resolution of 75–85 μm. Structures such as branches and the footplate of the stapes, chorda tympani, Jacobson’s nerve, and tympanic nerve branches, etc. can now be reliably visualized.
