In order to establish the diagnosis of cholesteatoma as early as possible it is useful tomake use of radiological methods in addition to case history, otoscopic and microotoscopic examination.High-resolution computed tomography (HRCT) is presently the method of choice for theexamination of pathology of temporal bone. The Otolaryngological Clinic of the Faculty ChildrenHospital in Brno, in collaboration with Radiological Clinic, performed a retrospective study comparingthe results of CT examination with subsequent surgical finding in patients, hospitalized forthe diagnosis of otitis media chronica cum cholesteatoma (OMCH) for the last 2.5 years. A total of47 scans were evaluated. The CT examination and operation findings were in agreement in 87%,whereas different findings were obtained in 13% (cholesteatoma being found during the operation,but not on CT scans). The main goal of the study was to demonstrate the presence or absence ofcholesteatoma. The results were aimed at analysis of validity of CT examination for the demonstrationof cholesteatoma relapses and the application of CT examination as a substitute of second-look.Key words: otitis media chronica cum cholesteatoma, high-resolution computer tomography.
otitis media chronica cum cholesetatomate, hight - resolution computed tomography.
