High-resolution computerized tomographic scans of the normal and abnormal ear
1982
Possible applications of high-resolution computerized tomographic scans to otology are discussed. On the basis of examples, the authors illustrate the normal structure of the ear as well as possible pathologic conditions such as congenital abnormalities, cholesteatoma, neoplasms, trauma, and systemic diseases. The advantages of the current generation of computerized tomographic scanners are reviewed, notably contrast potentialities, radiation load, reconstitution of images at a later time, and storage of imaging data. Drawbacks include the high acquisition price of the equipment and the limited mobility of the scanning gantry.
