Background and objective: High Resolution Computed Tomography (HRCT), a modification of routine Computed Tomography, provides a direct visual window into the temporal bone providing minute structural details. Purpose of the present study is to evaluate the normal anatomical variations involving the temporal bone. Materials and Methods: A cross-sectional study of 80 randomly selected HRCT temporal bone films were studied in the department of ENT at Navodaya Medical College, Raichur during the month of February 2017. The HRCT films were studied in both the coronal and axial planes with thin 2mm sections using ultra high algorithm obtaining both contrast and non-enhanced images. Results were tabulated using percentages. Results: In our entire series of 80 films, we found that the facial canal was dehiscent in 2 cases. In both the cases, the dehiscence was at the region of the oval window niche. Conclusion: HRCT is a revolutionary imaging modality that helps in evaluating the anatomical variations affecting the temporal bone. HRCT of temporal bone predicts certain normal anatomical variants of surgical significance preoperatively.
