Scientists accidentally discovered

In 2020, scientists at the Netherlands Cancer Institute made a surprising discovery while researching prostate cancer. During PET and CT scans involving radioactive glucose to highlight tumors, researchers noticed unexpected glowing areas in patients’ heads. These turned out to be previously unidentified salivary glands located behind the nose near where it connects to the throat. Named the tubarial glands, they were found in all 100 patients studied and confirmed through examination of cadavers, histology, and 3D imaging.

Dr. Wouter Vogel explained that the glands had likely gone unnoticed for centuries due to their location and the need for highly sensitive imaging. Until then, it was believed only microscopic mucous glands existed in that region. This marks the first new salivary gland discovery in 300 years. The glands, which help lubricate the upper throat area, are considered clinically significant. Researchers hope this finding can improve outcomes for cancer patients by sparing these glands during radiotherapy to enhance post-treatment quality of life.
