Spread and distribution of cholesteatoma in middle ear cleft

ABSTRACT

This study comprises fifty cases of chronic suppurative otitis media with cholesteatoma who underwent exploratory mastoidectomy. The main emphasis was to find out the extent and spread of cholesteatoma in and beyond the middle ear cleft. Most of the patients were those with far advanced cholesteatoma involving all parts of middle ear cleft [32 percent] and those with transgression of cleft confines [20 percent]. Cases with cholesteatoma limited to attic area were few [08 percent]
