Relationship of Preoperative Findings and Ossicular Discontinuity in Chronic Otitis Media

Abstract

In the cholesteatoma group, both cholesteatoma extension into the tympanic sinus and persistently draining ears were predictive of ossicular discontinuity. In the noncholesteatoma group, perforation edges adhering to the promontory also revealed a higher incidence of ossicular discontinuity. Therefore, all these findings can be considered as potential preoperative predictors of ossicular discontinuity in chronic otitis media.
