  • Title: Computerized tomography in hearing loss and disequilibrium states.
    Author: Hanafee WN.
    Journal: Otolaryngol Head Neck Surg; 1981; 89(5):861-6. PubMed ID: 6799923.
    Abstract:
    Computerized tomographic (CT) scanning for intracanalicular tumors requires air as a contrast agent within the internal auditory canal and special computer manipulations of the image to visualize small tumors. The same computer manipulations of CT scans provide detail of the middle and inner ear structures not available by non-CT tomographic techniques. The demonstration of horizontal semicircular canal fistula is one area in which CT scanning is clearly superior. Some pitfalls of the technique and interpretation of it will be discussed.
