Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 11
Abstract
Background And Objectives: HRCT, a modification of routine CT, provides a direct visual window into thetemporal bone providing minute structural details. Purpose of the present is to evaluate thenormal variations, pathological processes (infections, tumours and congenital anomalies)and their extent involving the temporal bone. Methods: A prospective study of 50 cases in patients with signs and symptoms of temporalbone pathology was done from February 2016 to October 2017. Patients were scanned inboth the coronal and axial planes with thin 2mm sections using ultra high algorithmobtaining both contrast and nonenhanced images. Results were tabulated usingpercentages. Results: Of 50 cases examined, we had 46 cases of ear infection out of which 22 cases were cholesteatoma, 20 cases of mastoiditis and 4 cases were malignant externa otitis, 3 cases of tumor and 1 traumatic case. Interpretation And Conclusion: HRCT is a revolutionary imaging modality that helps in evaluating the distributionfeatures, localization and assessing the extent of various pathologies affecting thetemporal bone.
