Objective To evaluate the diagnostic value of HRCT coronal and axial scanning in the diagnosis of chronic otitis media. Methods A retrospective collection of 68 cases of chronic otitis media with clinically and pathologically confirmed cases of otitis media. The preoperative HRCT crown, axial scanning signs and surgical pathological results of controlled analysis. Results 68 ears, cholesteatoma type 27 ears, the typical manifestations of the upper tympanic cavity, the sinuses and the inguinal mass clumps soft tissue, enlargement of the sinuses and their entrance, destruction of the tympanic dome, karner’s disappearance , The majority of sclerosing papillae; granuloma type 37 ears, mainly in the tympanic and sinuses sinus soft tissue, the degree of bone destruction is light, most of the baffled papilla; plain type 4 ears showed middle ear cavity The effusion to the main type of mastoid.
