Cholesteatoma Attic Retraction

Granulation tissue may arise from the mucosa adjacent to the cholesteatoma figure 6c.
Cholesteatoma attic retraction. Eustachian tube theory. This is the most common and widely considered as the main reason for cholesteatoma. There is an attic erosion partially exposing posterior half of drum deeply retracted and this pocket is full of keratin flakes. 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.
Skin material often accumulates in this pocket and becomes infected causing drainage and potential severe complications. The tube is a conduit between the middle ear and the nasopharyngeal space. A recurrent cholesteatoma is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present. Such causes can include for example poor eustachian tube function which results in retraction of the ear drum and failure of the normal outward migration of skin.
