  • Look Inside

The contralateral ears of 192 cases with aural cholesteatoma were analyzed. The incidence of bilateral cholesteatoma including pre-condition was 14.1%. Bilateral cholesteatoma was assumed to be congenital in origin, because its age di-. stribution is diffuse and most cases showed posterio-superior type of epithelial immigration. The importance of observation on contralateral ear was stressed.
