As mentioned an eardrum retraction is frequently caused by the infections we acquire.

Attic retraction ear drum. 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. Skin material often accumulates in this pocket and becomes infected causing drainage and potential severe complications. 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.

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. 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.
