Salivary gland biopsy is the removal of a small piece of tissue or cells from a salivary gland for examination.
Biopsy - salivary gland
How the test is performed
There are several pairs of salivary glands in different locations in the mouth:
A major pair in front of the ears (parotid glands)
Two major pairs on the floor of the mouth
Several minor pairs in the lips, cheeks, and tongue
One method of salivary gland biopsy is a needle biopsy . The skin over the gland is cleaned with rubbing alcohol. A local pain-killing medicine (anesthetic) may be injected, and a needle is inserted into the gland. A piece of tissue or cells are removed and placed on slides, which are sent to a laboratory for examination.
A biopsy can also be done to:
Determine the type of tumor in a salivary gland lump
Determine if the gland and tumor need to be removed
A biopsy of the glands in the lips or the parotid ...
Salivary gland tumors are abnormal cells growing in the ducts that drain the salivary glands.
Tumor - salivary duct
Causes, incidence, and risk factors
The salivary glands are located around the mouth. They produce saliva, which moistens food to help with chewing and swallowing.
Saliva contains enzymes that begin the digestion process, and help cleanse the mouth by washing away bacteria and food particles. By keeping the mouth moist, saliva helps to keep dentures, retainers, or other orthodontic appliances in place.
There are three pairs of major salivary glands. The largest are the parotid glands, located in each cheek over the jaw in front of the ears. Two submandibular glands are at the back of the mouth on both sides of the jaw. Two sublingual glands are under the floor of the mouth. There are also thousands of minor salivary glands around the rest of the mouth.
All of the salivary glands empty saliva into the ...
When you eat carbohydrates, digestion begins in the mouth. Your salivary glands secrete a hormone called salivary amylase that starts breaking down starches and other large carbohydrates into smaller carbohydrates and glucose.
Recent research has shown that different people contain different levels of this salivary amylase, and the levels are both genetic and environmental. People who are descended from populations that traditionally ate a lot of carbohydrates have a lot more salivary amylase; up to half the protein in their saliva can be amylase, whereas other people have hardly any at all.
Environmental influences include the amount of carbohydrate in your diet now, and stress.
Recently two scientists from Rutgers University in New Jersey and the Monell Chemical Senses Center in Philadelphia wondered if people with high levels of amylase (which they termed HA) would digest starches faster and hence have higher blood glucose (BG) levels than people with low level...
