Relationship between the different patterns of ossicularchain injury and the presence or absence of associatedcomplications in patients with cholesteatoma

Abstract

Introduction: Cholesteatoma is a benign lesion characterized by its expansive and destructive character, which may erode the temporal bone and generate intra- and extratemporal complications. Management is surgical, and goals include creating a safe and dry cavity, preventing recurrence of the disease, and improving hearing. Nationally and internationally, there is little literature where the main intrasurgi­cal findings of the ossicular chain in patients with this pathology are identified. Methodology: A descriptive retrospective cross-sectional study was conducted, covering the clinical records of patients diagnosed with cholesteatoma who un­derwent mastoidectomy treated at the Clinics Esimed Comfamiliar Pereira and Risaralda in the period between 1981 and 2016. Results: In total, there were 1410 patients with a diagnosis of cholesteatoma who were treated surgically; 65.6% (925 patients) were managed with the diagnosis of cholesteatoma without associa­ted complications. In most patients, ossicular chain compromise was found, and only 163 patients (11.5%) had an intact ossicular chain, the highest percentage associated with the diagnosis of cholesteatoma without associated complication (76.6%). When compromise of the ossicular chain was found, the most affected ossicle was the incus in 1181 patients (83.8%).
