Physicians may have discovered 4th pair of salivary glands in head

Alvand Hassankhani, MD, a radiologist at Philadelphia-based University of Pennsylvania, said he was reluctant to label the finding as “brand-new organs.” In addition to the 3 sets of recognized large salivary glands, small salivary glands are sprayed throughout the lining of the mouth and throat. The scientists might have just discovered a much better method to find a set of underappreciated minor glands, Dr. Hassankhani said.

Researchers analyzed scans from 100 patients with prostate or urethral gland cancer, 2 human cadavers, and information on the impact of radiotherapy on salivation and swallowing from 723 head-neck cancer patients..

The prospective 4th set needs sensitive imaging to find, said Dr. Wouter Vogel, radiation oncologist at Amsterdam-based Netherlands Cancer Institute and a study author, according to The New York Times. The bodys other large salivary glands can be felt, which is less practical for the 4th set tucked under the base of the skull, Dr. Vogel stated.

The brand-new find may discuss why people receiving radiation treatment for neck or head cancer so typically wind up with chronic dry mouth and swallowing problems, according to Dr. Vogel. No one has attempted to spare the unidentified glands from radiation.

The research study examined a limited client population, stated Valerie Fitzhugh, MD, a pathologist at Newark, N.J.-based Rutgers University. She added, “If its real, it could alter the method we look at illness in this area.”.

In addition to the three pairs of recognized big salivary glands, minor salivary glands are sprayed across the lining of the mouth and throat. The scientists might have just discovered a much better method to find a set of underappreciated minor glands, Dr. Hassankhani said.

The results might show a 4th type of salivary glands, the very first recognition of its kind in almost 300 years. Modern anatomy books show just three major types of salivary glands– one set near the ears, another under the jaw and another underneath the tongue..

Physicians in the Netherlands believe they have actually discovered a fourth pair of large salivary glands in the space where the nasal cavity fulfills the throat, according to a study in Radiotherapy and Oncology.
