Cholesteatoma is the most common neoplasm located at the CPA,[sup][1] and it wraps up the abducens nerve and grows toward the ventral side of pons.
There was no evidence of inflammation or cholesteatoma on the preoperative computed tomography scan of the temporal bone.
First is the persistence of disease inside the sinus due to incomplete removal and the second is increased risk for ossicular discontinuity and loss of hearing due to cholesteatoma within the sinus tympani.
However, open surgery and ossicular chain reconstruction should be conducted instead for middle ear- involved external auditory canal cholesteatoma, widely invasive cholesteatoma and infectious foci, intracranial and extracranial complications, and necrotic osteitis, aiming to allow dry ear canal by eliminating foci.
Basic radiologic patterns of cholesteatoma described on CT scan were assessed.
Cholesteatoma with granulations was the most common otoscopic finding in the unsafe ears [Table 2].
