Description

The staging system for congenital cholesteatoma developed by Potsic PW et al. in 2002 has been applied in several studies. In this staging system, we had not been able to evaluate the condition of auditory ossicle. In this study, we evaluated clinical features of the congenital cholesteatoma based on Potsic staging system (Potsic) and the staging criteria for cholestiatoma 2010 Japan (2010 cholesteatoma). Between 2001 and 2012, 52 patients (53 ears) with congenital cholesteatoma underwent surgery at our hospital. In stage III and IV in Potsic, success rates of hearing improvement were 80% (12/15) of S0, 100% (6/6) of S1, 62% (13/21) of S2 in 2010 cholesteatoma. These results suggested that the condition of stapes is important for hearing improvement.<br>We concluded that the staging criteria for cholesteatoma 2010 might be useful to calculate hearing improvement in congenital cholesteatoma.
