CT Evaluation of Temporal Bone Malignancies
Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2017, Vol 16, Issue 4
Abstract
Introduction: 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 and their extent involving the temporal bone along with their complications on HRCT and to correlate these imaging findings surgically, wherever available. Methodology: The prospective study included 30 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 30 cases, 40% had acoustic neuroma. The surgical and radiological findings showed a high level of sensitivity (95%) in the identification of acoustic neuroma. HRCT provides a good sensitivity of 93.3% 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 the evaluation of any congenital abnormality of the ear HRCT proved to be beneficial in depicting the anatomical details. Conclusion: The clinical and radiological findings showed a high level sensitivity with intra operative findings as regards to the presence of acoustic neuroma, changes of the internal auditory canal and erosion of the lateral semicircular canal. HRCT findings, in the treatment of any congenital abnormality of the ear were a good guide to the surgeon for planning and management.
