Cholesteatoma attic retraction.

Often there is an accumulation of squamous debris within the pocket figure 6a b. Primary acquired cholesteatoma or retraction cholesteatoma this form of cholesteatoma is due to a ventilation malfunction in the middle ear often caused by insufficient tube permeability. Granulation tissue may arise from the mucosa adjacent to the cholesteatoma figure 6c. Eustachian tube theory.

This is the most common and widely considered as the main reason for cholesteatoma. Skin material often accumulates in this pocket and becomes infected causing drainage and potential severe complications.
