ABSTRACT

Objective: This study aimed to study the prevalence of cholesteatomas and its complications and the effect it conducts on auditory ossicles. 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%. Otorrhea was found in 91.2%, hypoacusis in 87.8%, tinnitus in 32.7% and vertigo in 24.5%. Labyrinthine fistula was found in 2 cases and neurological symptoms (facial nerve palsy) in 4 cases. Erosion of ossicles was found in 79% with the Incus in 91.3%, Stapes in 50% and Malleus in 38%. 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.
