Recess of the Tympanic Eardor Posterior

The recess of the posterior eardrum (recessus membramae tympani posteriores, PNA, BNA, JNA; synonym: rear trellis pocket, posterior pocket of the eardrum) is a depression on the posterior wall of the external auditory canal, which is located at the level of the lower border of the eardrum.

The recess of the tympanic membrane is an important anatomical structure, as it provides drainage for fluid that accumulates in the middle ear. The recess is a continuation of the eardrum and consists of two parts: external and internal. The outer part of the recess is a wide gap leading to the external auditory canal, and the inner part is a narrow canal that opens into the middle ear.

In the process of evolution, the deepening of the eardrum has become an important anatomical element that ensures the normal functioning of the middle ear and prevents the development of infections. However, if the recess of the eardrum is disrupted or damaged, it can lead to fluid accumulation in the middle ear and the development of complications such as otitis media, mastoiditis and other diseases.

In humans, the recess of the eardrum can be disrupted or damaged for a variety of reasons. For example, this can happen with head injuries, middle ear surgery, or other medical procedures. In such cases, it is necessary to consult a doctor for diagnosis and treatment.

In addition, the deepening of the eardrum plays an important role in the development of speech and hearing. This is due to the fact that the recess allows sound to pass freely through the ear canal and transmits sound vibrations to the eardrum, where they are converted into nerve impulses.

Thus, the deepening of the eardrum is essential for the normal functioning of the middle ear, speech and hearing, and damage to it can lead to serious complications. Therefore, it is important to monitor the condition of this anatomical formation and, if necessary, consult a doctor.



An indented tympanic membrane is a defect in the form of a fissure or notch in the posterior portion of the membranous region of the middle ear. This disease can be caused by chronic inflammation or due to injury. Hearing impairment is the first sign of this pathology. Treatment consists of cleansing the membrane and removing inflammatory secretions, but surgery may also be required in advanced cases. Impaired sound perception of the hearing organ is one of the most common problems in the auricle and brain.
