Cholesteatoma Attic Retraction

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.

Cholesteatoma attic retraction.

A recurrent cholesteatoma is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present. There has been significant bone erosion of the ear canal wall above the eardrum. This is the most common and widely considered as the main reason for cholesteatoma. The tube is a conduit between the middle ear and the nasopharyngeal space.

Skin material often accumulates in this pocket and becomes infected causing drainage and potential severe complications. Invagination of the tympanic membrane of the attic to form retraction pockets to be filled with desquamated epithelium and keratin to form cholesteatoma. Eustachian tube theory. There is an attic erosion partially exposing posterior half of drum deeply retracted and this pocket is full of keratin flakes.

Often there is an accumulation of squamous debris within the pocket figure 6a b. 1 attic retraction pocket cholesteatoma is clearly visualized white arrow.
