The use of the computerized axial tomography has been well received in the field of otolaryngology. Five cases are presented illustrating the capability of the total body scanner (Delta scanner) to contribute to radiologic diagnosis below the level of the base of the skull. The advantages of non-invasibility and three dimensionality are compared to the disadvantages of added cost, added radiation exposure, comparatively long exposure time and relatively poor detail. Because of the overall usefulness of this diagnostic tool, evolution of rapid scanning devices with greater detail is awaited with interest.
