It’s hard to imagine there is a part of the human body that’s gone unnoticed by doctors after centuries of medical research.But that’s exactly what a group of scientists from the Netherlands believe. They said they have discovered a pair of previously overlooked glands that are hidden away in our skulls where the nasal cavity and the throat meet.
The medical researchers first came across the body part, which they propose naming tubarial glands, during a scan designed to look for tumorous growths. The scientists then looked at scans of the head and neck of a further 100 individuals they were treating for prostate cancer and dissected two cadavers — one male and one female. They all had a set.
The discovery was “thrilling” but the authors were “a bit skeptical” at first, said the study’s lead author Matthijs H. Valstar, a surgeon in the department of head and neck oncology and surgery at The Netherlands Cancer Institute.”We thought it wasn’t possible to discover this in 2020,” Valstar said. “It’s important it’s replicated and it should be done with different series of patients. It’s important to have confirmation of new medical findings.”
The glands cannot be seen with conventional methods of medical imaging like ultrasound, CT scans (computerized topography) or MRI (magnetic resonance imaging), the study authors said. The “unknown entity” was only identified when the doctors were using an advanced and new type of scan called PSMA PET/CT that has been used to detect the spread of prostate cancer. PSMA PET is shorthand for prostate-specific membrane antigen imaging using positron emission tomography.
Salivary glands show up clearly on this highly sensitive kind of imaging.”People have three sets of large salivary glands, but not there,” said study author Wouter Vogel, a radiation oncologist at The Netherlands Cancer Institute, in a news statement in May. “As far as we knew, the only salivary or mucous glands in the nasopharynx are microscopically small, and up to 1000 are evenly spread out throughout the mucosa. So, imagine our surprise when we found these.”
Many great scientific discoveries “come as a surprise — an incidental finding,” said Joy Reidenberg, a professor of anatomy at the Icahn School of Medicine at Mount Sinai in New York City, who wasn’t involved in the study.”Luckily, these researchers were tuned into the data, and were anatomically savvy enough to note the unusual brightness in a region that was not thought to contain any salivary glands,” Reidenberg added via email. “As the famous (late French biologist) Louis Pasteur once said: ‘Chance favors the prepared mind.'”
“For most patients, it should technically be possible to avoid delivering radiation to this newly discovered location of the salivary gland system in the same way we try to spare known glands,” Vogel said.”Our next step is to find out how we can best spare these new glands and in which patients. If we can do this, patients may experience less side effects which will benefit their overall quality of life after treatment.”
