Role Of HRCT In Evaluation Of Temporal Bone In Middle And Innner Ear Pathology

Abstract

Background: HRCT, a modification of routine CT, provides a direct visual window into the temporal bone providing minute structural details. Purpose of the present study is to evaluate the normal variations, pathological processes (infections, tumors and congenital anomalies) and their extent involving the temporal bone. Material And Methods: This study evaluating the efficacy of HRCT temporal bone finding among patients of middle and inner ear diseases in sir t. General hospital a cross sectional study. Result: Among the 70 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. Temporal bone trauma is forming second largest group of trauma patients in which longitudinal fracture of temporal bone is most common. Neoplasms formed the third largest group of lesions with acoustic neuroma being the most common tumor. Conclusion: 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.
