Abstract
To assesses the usefulness of a preoperative HRCT temporal bone and establish HRCT as an efficacious tool for diagnosis of the extent and involvement of adjacent structures by Cholesteatoma. The study group includes 52 patients with Unsafe CSOM (atticoantral), who presented to the ENT OPD at a tertiary care centre in Central India over a period of 18months, who underwent HRCT temporal bone followed by surgical exploration of middle ear and or mastoid, for the removal of Cholesteatoma. From the observation and results obtained from this study, we can conclude that the HRCT can be used as a standard radiological imaging modality for the evaluation of temporal Bone pathology. Despite its pitfalls such as more radiation exposure and higher cost, delineates the location and extent of the disease and provides critical information regarding anatomical variations and complications. It serves as a roadmap to assist the surgeon during surgery.
