Spectrum Of High-Resolution Computed Tomography Temporal Bone Findings In Chronic Suppurative Otitis Media

Abstract

Introduction: When it comes to providing great anatomic information, HRCT of the temporal bone is the most dependable and helpful imaging modality among those employed in the evaluation of chronic otitis media. It offers a clear visual window into the temporal bone, allowing it to exhibit minute anatomical and pathological characteristics. Methods: The department of radiodiagnosis and imaging at Meenakshi Medical College Hospital & Research Institute, Enathur, Kanchipuram, conducted this prospective cross-sectional study. 50 participants in all were enrolled in the trial for a duration of 1 year. Data were recorded and the results were compared to the post-operative results. 64 slices of a multidetector CT scan were used for HRCT. Calculations were made for sensitivity, specificity, accuracy, negative predictive value, and positive predictive value of different parameters. Results: In the present investigation, 50 participants were enrolled. Of them, 48% (24) were men and 52% (26) were women. HRCT revealed 100% sensitivity for erosion of the sigmoid plate and lateral semicircular canal. Cholesteatoma had a sensitivity of 79.06% and a specificity of 42.85%. Additionally, it provided a sensitivity of 75% and 95%, accordingly, for tegmen tympani and facial nerve canal erosion. Conclusions: For the pre-operative assessment of chronic otitis media, high-resolution computed tomography is a dependable diagnostic tool. It supports the surgical approach that helps avoid likely surgical problems and assists the operating surgeon in assessing the anatomic nature of the disease processes.
