WebCT scan is the imaging modality of choice to evaluate of cholesteatoma. It demonstrates a nonenhancing soft tissue lesion within the tympanic cavity with characteristic erosion of scutum and ossicles. Widening of the Prussak space will also be seen (Figure 18-7). Less commonly, erosion of the otic capsule is seen, resulting in perilymph fistula. WebTo compare the differential findings of tuberculous otitis media(TOM) with those of chronic sup purative otitis media with or without cholesteatoma, as seen on high resolution temporal bone CT.
