The idea of preserving the bony canal in surgery for chronic middle ear and mastoid disease is old, but the trend to preserve the bony canal in the presence of a cholesteatoma is a new fad—and a disconcerting one to many of us "old-timers."

The surgical microscope certainly is the key to the revolutionary improvement in ear surgery, but more is being expected of it than is reasonable. It is a false sense of security to believe that with 10, 16, or 25 power one can see every squamous cell of a cholesteatoma matrix. Begley and Williams1 presented a microscopic section of an evagination in a cholesteatomatous matrix that required staining with hematoxylin and eosin and 285 power to be seen. Certainly then, with the limited power of
