Background: Cholesteatoma is a potentially fatal non-neoplastic lesion of the temporal bone that is common in low-income communities in developing countries such as India. It is typified by the aberrant development of keratinizing squamous epithelium, which has invasive characteristics that might cause the middle ear cleft to alter destructively and perhaps result in major issues in the extracranial and cerebral areas.

Methods: The current study is set up as an observational study that will be conducted in the Department of Radiodiagnosis, KBN Institute of Medical Sciences, Gulbarga, Karnataka, India, between February 2016 to January 2017, with the approval of the ethics committee and the patients' written agreement.

Results: The study demonstrates that HRCT staging for middle ear cholesteatoma has a sensitivity of 85.6% and an excellent agreement and relationship with surgical results. The cholesteatoma sac, accompanying granulation tissue, mucosal edema, and effusion that could go unnoticed in HRCT pictures could be the cause of the underestimating of cholesteatoma at CT.

Conclusion: In order to reduce comorbidity, the surgeon can choose the optimum type of surgery to undertake with the use of the new non-invasive HRCT staging method proposed in this study for middle ear cholesteatomas.
