Attic Retraction Ear Drum

A retracted eardrum usually doesn t cause any symptoms.

Attic retraction ear drum. Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position. Fluid draining from the ear. However if it retracts enough to press on the bones or other structures within your ear it can cause. A recurrent cholesteatoma is a new cholesteatoma that develops when the underlying causes of the initial cholesteatoma are still present.

Allergies ablaze sinuses and respiratory unhealthiness among others cause the eustachian tube to be blocked not equalizing the air pressure on both ears thus leading to a retracted ear drum. 1 the tympanic membrane eardrum is visualized through the ear canal. If a dot of ink is placed on centre of the ear drum then its progress can be followed over the following few weeks as it moves to the edgae of the ear drum and then along the ear canal. Go to top long term retraction of the eardrum will cause erosion of the ear canal and forms a deep pocket.

The area of the superior portion of the eardrum is retracted or sucked in trapping skin cells and debris and eating away at the hearing bones and ear canal bone. Infections as mentioned an eardrum retraction is frequently caused by the infections we acquire. 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. In a cholesteatoma this property of skin movement fails and instead of the skin moving along the surface of the ear drum the skin builds up in the retraction pocket or sac and starts to form layers of dead skin.

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. Eventually the pocket may trap skin forming a skin cyst or cholesteatoma. 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. Further progression of retraction pockets can cause destruction of the eardrum.
