Clinical Study of Congenital Middle Ear Cholesteatoma: Experience of 23 surgical cases

Abstract

We studied 23 patients (23 ears) with congenital cholesteatoma who underwent surgery at our department from January 1998 to December 2008, focusing on the localization and type of cholesteatoma, surgical procedures and results. We used a staging system which was developed by Potsic PW et al. at 2002. The ratio of the posterior quadrant and open type cholesteatoma increased, with progression of stages. Second look operation was done in 60% of stage III and 75% of stage IV cases, thereafter residual cholesteatoma was found in 20% of stage III and 75% of stage IV cases. In addition, we have reviewed the surgical procedures of anterior quadrant cases, and proposed a current surgical procedure.
