If the disease is difficult to remove, so that there is an increased risk of residual disease, then removal of involved ossicles in order to fully clear cholesteatoma has generally been regarded as necessary and reasonable. In other words, the aims of cholesteatoma treatment form a hierarchy. The paramount objective is the complete removal of cholesteatoma. The remaining objectives, such as hearing preservation, are subordinate to the need for complete removal of cholesteatoma. This hierarchy of aims has led to the development of a wide range of strategies for the treatment of cholesteatoma. Surgery
The variation in technique in cholesteatoma surgery results from each surgeons judgment whether to retain or remove certain structures housed within the temporal bone in order to facilitate the removal of cholesteatoma. This typically involves some form of mastoidectomy which may or may not involve removing the posterior ear canal wall and the ossicles. Removal of the canal wall facilitates the complete clearance of cholesteatoma from the temporal bone in three ways: 

It removes a large surface onto which cholesteatoma may be adherent;
It removes a barrier behind which the cholesteatoma may be hidden;
It removes an impediment to the introduction of instruments used for the removal of cholesteatoma.Thus removal of the canal wall provides one of the most effective strategies for achieving the primary aim of cholesteatoma surgery, the complete removal of cholesteatoma. However, there is a trade-off, since the functional impact of canal wall removal is also important.
