The retracted segment of eardrum is often known as a retraction pocket. The eardrum is draped over the incus stapes and round window. Results from eustachian tube dysfunction and tympanic membrane retraction with debris and keratin eventually obstructing the neck of the retraction.

However if it retracts enough to press on the bones or other structures within your ear it can cause. 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.
