Abstract: Objective To evaluate erosion of scutum in the diagnosis of middle ear cholesteatoma by high-resolution CT scan(HRCT). Methods HRCT findings of 38 patients(in 42 ears)with middle ear cholesteatoma in our department were reviewed. The condition of the scutum was observed with CT scanning and surgical findings. Result There are 37 ears with erosion of scutum, 4 ears with marginal/central perforation and 1 ear with intact tympanic membrane. Conclusion Scutum erosion demonstrates an important role in the diagnosis of cholesteatoma of middle ear, however, this sign cannot be found in some patienas with cholesteatoma.

Key words: High-resolution CT, Scutum, Cholesteatoma
