Temporal Bone and Auditory Pathways

  • J. W. Casselman


Today the anatomy of the temporal bone can be evaluated in detail. Computed tomography (CT) is the method of choice to look at the external ear and middle ear. But CT also provides much information about the inner ear. New CT equipment, using helical scanning and multidetector technology, enables us to scan the temporal bone in detail. Once the images are made, one can recalculate them even every 0.1 mm. On these very thin images, partial volume is no longer a problem and hence every tiny structure can be seen. Moreover, excellent multiplanar reconstructions can be made. Structures like the branches and footplate of the stapes and chorda tympani can now be evaluated in a reliable way.
