One hundred sixty six patients, 86 [51.8%] males and 80 [48.2%] females, who were admitted with clinical diagnosis of chronic suppurative otitis media, with cholesteatoma. Analysis of the patterns of extension of cholesteatoma, showed that the tympanic cavity was involved in [91.6%], mastoid cavity in [74%] and Eustachian orifice in [42%] of our patients. In the Tympanic cavity, oval window [46%] and sinus tympani [40%] were involved. The most common patterns of extension included tympanic cavity.
