Abstract :

Background: Cholesteatoma is dangerous condition diagnosed by otoscopic examination and treated by surgery. This study assesses the usefulness of a pre-operative high-resolution CT scan in depicting the status of the middle ear structures in the presence of cholesteatoma. Aim and Objective: To study the role of HRCT temporal bone in pre-operative evaluation of cholesteatoma. Materials and Methods: Total 64 cases with clinically suspected cholesteatoma were selected for the study. The important per-operative surgical findings were correlated with pre-operative HRCT findings. Results: This study showed good correlation between the preoperative findings and intra operative findings. Conclusion: HRCT enabled the extent of 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 and more conservative procedure can be used to eradicate the disease.
