Scientists in the Netherlands have discovered a previously unknown pair of salivary glands at the back of the throat.
The researchers used prostate-specific membrane antigen (PSMA), a protein found in high concentrations in prostate tissue as well as salivary glands bound to a radioactive marker. Patients then underwent a PET (nuclear imaging) and a CT (which uses X-rays) to produce the image above.
Strangely, these salivary glands, although macroscopic, have never been seen before. One of the reasons this study is important is that one of the complications of radiation therapy is a reduction in saliva production. Scientists are looking for ways to alleviate this side effect and knowing the location of these new salivary glands will help future patients.
The researchers are suggesting the name “tubarial salivary glands” for their discovery.
