Abstract
Background: Cholesteatoma is potentially dangerous condition as it can extend and erode into adjacent structures and can cause various serious complications. HRCT temporal bone very clearly depicts the anatomy of various small important structures in middle and inner ear cavity. Hence it is an excellent modality and investigation of choice in diagnosing and defining the extent of cholesteatoma. It has become essential investigation in preoperative planning for surgeon. Present study shows good correlation of various preoperative HRCT findings with intraoperative findings.

Aims & Objective: To study the role of HRCT temporal bone in pre-operative evaluation of cholesteatoma.

Material and Methods: Total 35 cases with clinically suspected cholesteatoma were selected for this study. All the patients were from Sir Sayajirao General Hospital, Vadodara and were scanned at the CT scan, Radiology Department of the hospital. The important intra-operative surgical findings were correlated with pre-operative HRCT findings. The results were analyzed, studied and compared with similar studies of the past.

Results: Present study shows good correlation between the preoperative findings of cholesteatoma by HRCT temporal bone and intraoperative surgical findings.

Conclusion: In present study HRCT enabled the pre-operative delineation of the cholesteatoma and the recognition of its manifestations and complications. HRCT is confirmed to be valuable in the diagnosis and in guiding the surgical management of cholesteatoma.
