Abstract
BACKGROUND: Cholesteatoma is a serious otological condition requiring detailed imaging for effective surgical planning. High-resolution computed tomography (HRCT) of the temporal bone is pivotal in preoperative evaluation. OBJECTIVES: To evaluate the accuracy of HRCT in determining the extent of cholesteatoma and its correlation with intraoperative findings. METHODS: A retrospective study was conducted on patients with suspected cholesteatoma who underwent HRCT followed by surgery. Observations from HRCT were compared with intraoperative findings. RESULTS: HRCT effectively identified bone erosions, ossicular chain involvement, and disease extent. The sensitivity and specificity of HRCT in detecting ossicular erosion and other key parameters were notable. CONCLUSION: HRCT is indispensable in evaluating cholesteatoma, thus aiding in surgical decision-making and reducing intraoperative surprises.
