Tympanic membrane retraction describes a condition in which a part of the eardrum lies deeper within the ear than its normal position.. 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.
The larger pars tensa consists of three layers: skin, fibrous tissue, and mucosa. Its thick periphery forms a fibrocartilaginous ring called the annulus tympanicus or Gerlach's ligament.

The operation is performed with the patient supine and face turned to one side. The graft material most commonly used for the surgery is temporalis fascia.
In human anatomy, Prussak's space is the small middle ear recess, bordered laterally by the flaccid part of Shrapnell's membrane, superiorly by the scutum (a sharp bony spur that is formed by the superior wall of the external auditory canal) and lateral malleal ligament, inferiorly by the lateral process of the malleus, and medially by the neck of the malleus.
