Role of High Resolution Computed Tomography in Evaluation of Pathologies of Temporal Bone.
Journal Title: International Journal of Medical Science and Innovative Research (IJMSIR) - Year 2019, Vol 4, Issue 4
Abstract
Background: High Resolution Computed Tomography (HRCT), a modification of routine CT, provides a direct visual window in the temporal bone providing minute structural details. Purpose of the present study was to evaluate the normal variations, pathological processes (infections, tumours, trauma and congenital anomalies) and their extent involving the temporal bone along with their complications on HRCT and to correlate these imaging findings surgically, wherever available. Materials and Methods: The prospective study included 40 patients who were referred to the radiology department with clinically suspected temporal bone or ear pathologies. After detailed clinical examination, the patients were subjected to high resolution computed tomography (HRCT) examination. The imaging findings were correlated with the surgical findings wherever available. The surgical findings were considered as final. Results: From a total of 40 cases, 83.33% had cholesteatoma. The surgical and radiological findings showed a high level of sensitivity (95.65%) in the identification of cholesteatoma. HRCT provides a good sensitivity of in the identification of changes to the ossicular chain despite the presence of surrounding soft tissue. HRCT was highly informative in identification of erosion of lateral semicircular canal. In diagnosis of facial canal dehiscence HRCT had a low sensitivity. In the evaluation of any congenital abnormality of the ear HRCT proved to be beneficial in depicting the anatomical details. Conclusion: Good agreement between HRCT and operative findings with respect to soft tissue extension, bony boundaries of tympanum, mastoid pneumatization, status of ossicular chain, facial nerve canal and fistula of lateral semi-circular canal were excellent Hence HRCT plays an important role in pre-operative evaluation, guiding the surgical management.
