Abstract: Introduction: The study addresses the diagnostic challenges in evaluating temporal bone pathologies using conventional imaging methods and explores the enhanced capabilities of HRCT in providing detailed visualizations crucial for accurate diagnosis and effective management. Methodology: A diverse cohort of 126 patients suspected of temporal bone pathologies was examined using a 128 - slice CT scanner at R. D. Gardi Medical College, Ujjain. The HRCT protocol was meticulously designed to minimize radiation while maximizing diagnostic yield. Ethical guidelines were strictly followed, with data analyzed for detailed diagnostic insights. Results: The cohort's mean age was 20.98 years, with a slight male predominance (51.6%). HRCT diagnosed CSOM in 41.3% of cases, CSOM with cholesteatoma in 28.6%, and less frequent pathologies such as otitis externa (4.8%) and acoustic neuroma (1.6%). Key anatomical findings from HRCT included significant ossicular erosion (27% for incus erosion), granulation tissue presence in 63.5% of cases, and mastoiditis in 62.7%. The technique proved particularly effective in identifying complications, with meningitis occurring in 11.1% of cholesteatoma patients and brain abscesses in 8.3%. Conclusion: HRCT is an indispensable tool in the diagnosis and management of temporal bone pathologies, offering superior visualization that significantly enhances surgical planning and patient care. Its detailed imaging capabilities allow for earlier detection of complex pathologies and complications, leading to improved treatment outcomes.
