Role of High Resolution Computed Tomography in Temporal Bone Pathology

Background: High-Resolution Computed Tomography (HRCT) has become the gold standard for evaluating temporal bone pathologies due to its superior spatial resolution and ability to delineate fine bony and soft tissue structures.

Objective: To assess the diagnostic utility of HRCT in detecting and characterizing temporal bone disorders, including inflammatory, traumatic, and neoplastic conditions.

Materials and Methods: A descriptive cross-sectional study was conducted on 50 patients presenting with suspected temporal bone pathologies at the Radiology Department of Maharishi Markandeshwar Institute of Medical Sciences and Research (MMIMSR), Mullana, Ambala. HRCT scans were analyzed for clinical indications, demographic patterns, and pathological findings. Data were summarized using descriptive statistics.

Results: The most affected age groups were 31–40 years (24%) and 21–30 years (20%), with a male predominance (56%). Common clinical presentations included ear discharge (36%) and ear pain (18%). HRCT identified otomastoiditis (30%), cholesteatoma (22%), CSOM (20%), fractures (8%), and tumours (8%).

Conclusion: HRCT is a reliable, non-invasive imaging modality that provides accurate diagnosis, guides surgical planning, and improves management of temporal bone pathologies.
