Further progression of retraction pockets can cause destruction of the eardrum.
Attic retraction ear drum.
A retracted eardrum is one that appears concave.
The ear canal and ear drum are covered with skin but down the ear canal there is no friction so the skin grows in a different way.
As mentioned an eardrum retraction is frequently caused by the infections we acquire.
1 attic retraction pocket cholesteatoma is clearly visualized white arrow.
Skin material often accumulates in this pocket and becomes infected causing drainage and potential severe complications.
The surface layer of the skin on the ear drum moves over the surface of the ear drum and along the ear canal before before shedding and mixing with the oils produced in the outer part of the ear canal to form wax.
Medical professionals may also call a retracted eardrum middle ear atelectasis to understand the conditions that may cause this you must first understand a little bit about the eardrum called the tympanic membrane and the normal physiology of the middle ear.
Tympanic membrane retraction is a condition where a part of the eardrum becomes weakened and loose and is pulled inwards by the negative pressure of the middle ear.
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.
The eardrum is draped over the incus stapes and round window.
Long process of incus attic retraction and middle ear effusion visible post ear wax removal 342 duration.
A retracted eardrum usually doesn t cause any symptoms.
However if it retracts enough to press on the bones or other structures within your ear it can cause.
The membrane can drop over the ossicles and cause a variety of symptoms.
Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.
There has been significant bone erosion of the ear canal wall above the eardrum.
In a retrospective study of 345 patients with middle ear cholesteatoma operated on by the same surgeon the overall 5 year recurrence rate was 11 8.
Fluid draining from the ear.
Many of theses eardrums have tympanosclerosis or white plaques on the eardrum.
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.
