The posterior parotid veins (v.parotideae posteriores) are branches of the internal jugular vein, which pass through the parotid gland and empty into the external jugular vein. They ensure the outflow of blood from the parotid gland and adjacent tissues.
The parotid gland is a paired organ located on the side of the face, under the cheek. It plays an important role in the production of saliva and the secretion of secretions, which protect the oral mucosa from bacteria and microorganisms.
The posterior parotid veins pass through the parotid openings located on the lateral side of the parotid gland. They collect blood from the upper part of the parotid gland, as well as from surrounding tissues such as skin and muscle.
One of the functions of the posterior parotid veins is to ensure the outflow of blood from the parotid glands and adjacent soft tissues, which allows them to maintain their normal functioning. In addition, these veins participate in blood circulation in the face and head, ensuring the outflow of venous blood from this area.
If the venous outflow from the parotid gland or adjacent tissues is impaired, various diseases can occur, such as swelling and inflammation of the parotid gland (mumps), as well as impaired blood supply to the head and face.
It is important to note that the posterior parotid veins are important components of the venous system of the face and head. Their violation can lead to serious health consequences and requires timely treatment.
Here is an article about the veins of the parotid (anterior) gland, or more precisely about the posterior veins - v.parotideae posteriores.
The veins of the parotid glands originate from each parotid fatty tissue, the upper pole of the hyoid bone, the triangular bone triangles in the thickness of the mastoid process at the zygomatic arch and the superficial fascia of the face. They accompany the internal lateral muscle group and are surrounded by the cheek muscles. The vein enters the cranial cavity at the level of the greater wing of the sphenoid bone medial to the posterior ethmoidal foramen.
