Cholesteatoma ear with increased bone conduction threshold should no more be missed - A prospective study

Background: Cholesteatoma is a collection of keratinized squamous epithelium in middle ear and pneumatic areas of temporal bone. It can be said as an invasive disease which is often associated with sensorineural hearing loss. It is seen that hearing loss varies with the location of disease, duration of disease, and extension of cholesteatoma. Aims and Objectives: The aim of this study is to see the association of cholesteatoma and bone conduction threshold difference as compared to contralateral normal ear. Materials and Methods: This study was done between August 2019 and December 2021 at our tertiary care center. It is a prospective study of 50 patients. Results: In our study, we saw that there is a considerable sensorineural hearing loss associated with cholesteatoma depending on which varies with location and extension. Conclusion: Our study shows that the more extensive the cholesteatoma more is the sensorineural hearing loss.
