Histological studies on the early genesis of cholesteatoma are limited, and for this reason interpretation of such findings and theoretical deductions are somewhat varied.

The various theories of attic and middle ear cholesteatoma genesis have recently been discussed by Fernandez1 and will not be reviewed in detail here. The metaplasia concept of cholesteatoma origin is considered by both Fernandez and Harris2 as lacking clinical or experimental
