The picture on the far right shows a severely retracted eardrum with attic retraction pocket formation.
Ear attic retraction pocket.
Often there is an accumulation of squamous debris within the pocket figure 6a b.
This retraction pocket is still cleaning itself but the extent of the pocket can not be seen.
The ear drum has dropped further in and has worn through the middle hearing bone arrow 1 and is now lying against the inner wall of the middle ear space.
Eardrum is strongly retracted one can not determine the exact position of its banks the destruction of the lateral wall of the attic is larger and the epithelium begins to grow into the back forming the initial stage of cholesteatoma.
Many of theses eardrums have tympanosclerosis or white plaques on the eardrum.
The eardrum is draped over the incus stapes and round window.
However if it retracts enough to press on the bones or other structures within your ear it can cause.
The the photo 3 you can see the uncontrolled retraction pocket in epitympanum.
1 attic retraction pocket cholesteatoma is clearly visualized white arrow.
The eardrum comprises two parts the pars tensa which is the main part of the eardrum and the pars flaccida which is a smaller part of the eardrum located above the pars tensa either or both of these parts may become retracted.
Fluid draining from the ear.
Further progression of retraction pockets can cause destruction of the eardrum.
A retraction pocket seen in the attic or posterosuperior quadrant of a tympanic membrane is the hallmark of an acquired cholesteatoma.
Attic retraction pocket in the left ear white arrow with atelectatic prussak s space red circle and eroded scutum yellow arrow.
The ear drum has worn away a lot of the middle hearing bone.
The basal cells of germinal layer of skin proliferate under the influence of infection and lay down keratinising squamous epithelium.
Granulation tissue may arise from the mucosa adjacent to the cholesteatoma figure 6c.
A retracted eardrum usually doesn t cause any symptoms.
Invagination of tympanic membrane from the attic or part of pars tensa in the form of retraction pockets lead to the formation of cholesteatoma.
There has been significant bone erosion of the ear canal wall above the eardrum.
