Abstract :

HRCT, a modification of routine CT, provides a direct visual window into the temporal bone providing minute structural details. Purpose of the present is to evaluate the normal variations, pathological process (infections, tumours and congenital anomalies ), trauma and their extent involving the temporal bone. A prospective correlational study of 50 cases in patients with signs and symptoms of temporal bone pathology was done from March 2018 to may 2019. Patients were scanned in both the coronal and axial planes with thin 0.6 mm sections using ultra high algorithm obtaining both contrast and nonenhanced images. Results were tabulated using percentages. Amongst the 50 cases which were studied, infection was found to be the most common pathology affecting the temporal bone with increasing preponderance in the younger age group. Trauma found to be second largest group with longitudinal fractures being most common with increasing incidence in younger age male group. Neoplasms formed the third largest group of lesions with acoustic neuroma being the most common tumour. HRCT is a revolutionary imaging modality that helps in evaluating the distribution, features, localization and assessing the extent of various pathologies affecting the temporal bone. Hrct is helpful modality in assessing the need for surgery in syndromic patients, in treatment approach and road mapping for surgical planning for temporal bone pathologies.
