Many imaging modalities are available for the evaluation of the temporal bone of which high-resolution computed tomography (HRCT) plays a crucial role in demonstrating the detailed anatomy of the temporal bone and assessing the disease extent. Careful and thorough evaluation is needed for middle and inner ear lesions for the early diagnosis and treatment of the disease, to prevent complications and to determine the best surgical approach. The purpose of this study is primarily to understand the capability of HRCT in diagnosis and detection of pathologies of the temporal bone.
