Anterior Eardrum Pocket

The eardrum recess is an anatomical structure that is located on the anterior wall of the middle ear. It is a small pocket that contains the eardrum. This structure is an important part of the middle ear as it protects the eardrum from damage and infection.

The anterior recess of the eardrum (PCA) is one of two pockets of the eardrum. It is located on the front of the eardrum and is shaped like a crescent. The PCA is one of the largest pockets of the tympanic membrane and its volume can reach up to 0.2 ml.

The PCA plays an important role in the functioning of the middle ear. First, it protects the eardrum from infection and damage. Secondly, the PCA ensures the normal functioning of the middle ear because it contains fluid that moisturizes the eardrum and helps it move in response to sounds.

Changes in the PCA can lead to various middle ear diseases such as otitis media or eustachitis. Therefore, if you have problems with PCA, it is necessary to see a doctor for diagnosis and treatment.

**The tympanic membrane pocket** is a special depression located on the inner surface of the anterior wall of the tympanic bladder, which serves to accommodate the anterior section of the posterior leg of the malleus. In the normal state, the aqueduct of the tympanic cavity and the tympanomastoid canal open into it. RMA is drained
