Groove of the Pharyngeal-Tympanic Tube

The groove of the pharyngotympanic tube is an important anatomical formation in the head and neck region. It is a groove on the back of the pharynx that continues down and into the tympanic cavity of the middle ear. The groove of the pharyngotympanic tube is located between two muscles: the cricoid and the arytenoid.

This groove is important for the functioning of the middle ear, as it provides access to the eardrum and the auditory ossicles. In addition, the groove of the pharyngotympanic tube is involved in the formation of an opening through which air enters the eardrum.

During middle ear surgery, such as cataract removal or ossicular replacement, it may be necessary to access the pharyngeal-tympanic groove. This can be done using an endoscope or other special instruments.

It is important to note that the pharyngeal-tympanic groove can become damaged or blocked due to various medical conditions such as tumors, infections or trauma. In such cases, surgery may be required to restore normal function of the sulcus.

In general, the pharyngeal-tympanic groove is an important anatomical element that plays an important role in the functioning of the middle ear and can be affected in various pathologies.

The groove of the pharyngeal tympanic tube (sulclus tebae pharyngetroaenitca, tina) is the connection of the canal space between the posterior cranial fossa and the pharyngeal tube on one side and the middle ear on the other. The grooves of the pharyngeal tubal canal provide access to the pharyngeal muscles, which are used to regulate breathing, as well as to the auditory ossicles of the middle ear, which are responsible for transmitting sound to the brain. The grooves also ensure the free functioning of the epiglottis, which moves along this tube. Disruption of the normal movement of this organ can lead to breathing problems. The canal openings, located in the pharynx and middle ear, provide normal ventilation of the lungs and sound conduction. Since both of these structures have a direct connection, any disturbances in them can negatively affect these processes. The method of formation of the pharyngeal-tympanic tube occurs in the third week of intrauterine development from the action of the rhinogenic impulse to the cheek, from which the pharyngeal muscles are primarily formed, while they already contain skeletal elements in their muscles. The processes of the 2nd whorl of the second branchial arch act on the canal directed into the oral cavity and form an outgrowth of the medial part of the first visceral arch. Then the cartilaginous plates grow together, creating a cavity of the pharyngeal tube with two openings: inlet and outlet. The inlet is connected to the nasal cavity, and the outlet is connected to the tympanic cavity. The loss of the second arch at the final stage of skeletal embryogenesis forms the intermaxillary gap.
