Cases of tension-type cholesteatoma at Kumamoto University

Abstract

We herein report the postoperative results of tension-type cholesteatoma performed at Kumamoto University. Successful cases accounted for 70% of the total, which was a comparable rate to that in other facilities. For second-stage surgery, no recurrence of remodeling was observed, but eight cases of residual recurrence were observed. Six of these cases had remnants around the stapes. However, during the observation period (mean two years, nine months), neither residual recurrence nor remodeling recurrence was observed. Tension-type cholesteatoma destroys the area around the stapes at an early stage, and S2 cases with the degree of stapes lesions are more likely to have residual recurrence than X and sufficient cleaning with an endoscope.
