Attic Retraction Grading

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.

Attic retraction grading. Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position. Retraction pockets can be divided into controlled and uncontrolled and the difference stems from the possibility of assessing its interior.

Characon used broad groups based on accessability and controllability with the retraction being mobile fixed to undeterminable end not visible 5. Retractions of grafts are predicted by mode of. All attic retraction pockets could be classified precisely using the new classification system. Controlled and movable controlled and immovable uncontrolled and immovable.
