[The application of spiral CT in diagnosing the otitis media with cholesteatoma].
OBJECTIVE
To discuss the application of spiral CT imaging of temporal bone in diagnosing the chronic otitis media with cholesteatoma.


METHODS
The clinical data and spiral CT manifestation of 104 cases of chronic otitis media with cholesteatoma were retrospectively analyzed. All the diagnoses were confirmed by operation and pathology.


RESULTS
Spiral CT imaging could accurately show the signs of soft-tissue occupancy and bony-erosion of by cholesteatoma in middle ear which originated from various sites and of various sizes. Comparing the CT imaging before surgery and the findings during the operation, the consistency in bone erosion was 89.1%, in soft-tissue occupancy was 94.4% and in invasion of ossicle chain was 89.3%.


CONCLUSIONS
Spiral CT imaging plays an important role in diagnosing cholesteatoma and especially the bony-erosion and the soft-tissue occupancy, which can provide crucial information for the surgery.
