Objective To investigate the value of HRCT in the diagnosis of cholesteatoma otitis media. Methods Twenty - six cases of cholesteatoma otitis media were confirmed by operation and pathology. The HRCT findings were retrospectively analyzed and compared with the surgical results. Results HRCT of cholesteatoma otitis media mainly showed soft tissue mass (10%, 266%) in the upper tympanic cavity, the sinonasal and mastoid area, which was often accompanied by bone destruction, including the destruction of the ossicles (92%, 24 The damage of the shield plate (46%, 1226), the destruction of the facial nerve canal (54%, 1426) and the destruction of the sigmoid sinus wall (7.7%, 226) were observed. Middle ear sinus enlargement, bone margin hardening. There are intracranial complications, including temporal lobe abscess (1 case) and otogenic meningitis (1 case). Conclusion HRCT has a positive diagnostic value for cholesteatoma otitis media, which has an important guiding significance for clinical practice
