Attic Area Of Tympanic Membrane

The left hand picture shows a very thin or atelectatic eardrum tympanic membrane which is draped over the promontory and round window nitch.

Attic area of tympanic membrane.

Invagination of tympanic membrane from the attic or part of pars tensa in the form of retraction pockets lead to the formation of cholesteatoma. Hypotympanum inferior to the membrane. 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 perforations a perforation is a hole in the tympanic membrane that is visible through the otoscope.

July 6 2019 by zamira leave a comment. To formulate a reliable classification of tympanic membrane retraction which is easy to use but capable of detecting small differences in retraction. Epitympanum attic epitympanic recess superior to the membrane. The eardrum is draped over the incus stapes and round window.

According to this observation retraction may occur easily in the postoperative attic area especially in the obliterated cases even though the eustachian tube function is normal. Mesotympanum directly medial to the membrane. The classification was developed from observations dividing the drum into 3 areas. No postoperative perforation of the tympanic membrane was detected in any of the 98 patients in our series.

The tympanic cavity is subdivided into several parts defined in relation to the planes of the tympanic membrane some authors define three compartments 4.

The pars tensa anterior to the malleus type i posterior to the malleus subdivided into upper and lower. Tympanic membrane also called eardrum thin layer of tissue in the human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles which are tiny bones in the tympanic middle ear cavity.
