ABSTRACT

Objective: This study aimed to study the prevalence of cholesteatomas, the effect it conducts on auditory ossicles and the hearing loss using the values of air conduction (ac), bone conduction (bc) and air-bone gap (ABG). Materials and Methods: This study was a retrospective study of the files of the patients who reviewed AlMouwasat University Hospital and were diagnosed with middle ear cholesteatomas. This study included all cases from 1/1/2016 to 30/11/2019. Only the authors to ensure the privacy collected all the data and all the names and personal information were blinded. Statistical analysis was done using SPSS 25.0. Results: 27% of all patients were children (≤16 years old) and 73% were adults (>16 years old). Males were more dominant with 54% compared to females with 46%. Erosion of ossicles was found in 79% with the Incus in 91.3%, Stapes in 50% and Malleus in 38%. The ac, bc and abg values are shown in the table below. Conclusion: The etiology of cholesteatomas remains unknown. Bigger epidemiological and statistical data, surgical reports, and conclusions of experimental studies are needed, as they may provide support for clarifying the pathogenesis of cholesteatoma.

Keywords: The etiology of cholesteatomas remains unknown.
