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.

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
