Tubarial salivary gland

Tubarial Salivary Glands

The Tubarial Salivary Glands are a set of salivary glands located in the human pharynx. They were first identified in 2020 by a team of Dutch scientists using PSMA-PET/CT imaging techniques. The discovery of these glands could have significant implications for the treatment of head and neck cancer.

Anatomy

The Tubarial Salivary Glands are located over the torus tubarius, a structure in the nasopharynx, hence the name. They are found in a space where the nasal cavity meets the throat, behind the nasal septum. The glands are approximately 1.5 inches (3.81 cm) in length.

Function

Like other salivary glands, the Tubarial Salivary Glands produce saliva, which aids in digestion, keeps the mouth moist, and helps protect against tooth decay. The exact contribution of these glands to overall salivary production and function is still under investigation.

Clinical Significance

The discovery of the Tubarial Salivary Glands has potential implications for radiation therapy in patients with head and neck cancer. Previously, radiation oncologists attempted to spare the three known major salivary glands from high doses of radiation to prevent complications such as xerostomia (dry mouth). Now, the Tubarial Salivary Glands can also be spared to further reduce the risk of xerostomia.
