High-Resolution Computed Tomography of Cholesteatomatous Otitis Media: Significance of Preoperative lnformation

High resolution computed tomography (CT) of the middle ear and mastoid, when properly performed and interpreted, is valuable to the otologic surgeon prior to exploration of the cholesteatomatous ear. Fifty one patients with cholesteatomatous otitis media underwent CT examination of both ears one to four weeks prior to surgery. These CT findings were then compared with operation findings. We analysed sixteen parameters of the anatomical and pathological features of the temporal bone affected by cholesteatoma. In conclusion, a high degree of correct correlation was noted between CT findings and those of the operation. Our study showed the usefulness and accuracy of preoperative computed tomographic study in cholesteatomatous otitis media.
