OBJECTIVEHigh Resolution Computed Tomography (HRCT), a modification of routine CT, provides a direct visual window in the temporal bone providing minute structural details. Purpose of the present study was to evaluate the suppurative diseases of middle ear and mastoid with their complications on HRCT and to correlate these imaging findings surgically. Our study shows good correlation of various HRCT findings in suppurative diseases of middle ear & mastoids with intra-operative findings. MATERIALS AND METHODSThis retrospective study included 60 patients who were referred to the Department of Radiodiagnosis, Assam Medical College with clinically suspected temporal bone or ear pathologies. After detailed clinical examination, the patients were subjected to HRCT examination. The imaging findings of all cases were correlated with the surgical findings. RESULTSOut of 60 patients, 63.3% had unsafe CSOM with cholesteatoma. The HRCT findings with surgical correlation showed a high 91.89% sensitivity for identifying cholesteatoma. HRCT also provided good sensitivity for detecting erosion of scutum (90.32%), erosion of ossicular chain (86.96%) and erosion of lateral semi-circular canal (80%). HRCT had lower sensitivity (66.67%) for identifying facial canal dehiscence. CONCLUSIONThe HRCT findings showed a good sensitivity with intraoperative findings in identification of cholesteatoma, erosion of scutum, ossicular chain and semi-circular canal.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
