A biopsy of the glands in the lips or the parotid gland can also be performed to diagnose diseases such as Sjogren syndrome.
You do not need to prepare for a needle biopsy, there is no special preparation. You may be asked not to drink or eat anything for a few hours before the test.
For surgical removal of a tumor, preparation is the same as for any major surgery. You will not be able to eat anything for 6 to 8 hours before the surgery.
With a needle biopsy, you may feel some stinging or burning if a local as numbing medicine is injected.
You may feel pressure or mild discomfort when the needle is inserted. This should only last for 1 or 2 minutes.
The area may feel tender or be bruised for a few days after the biopsy.
The biopsy for Sjogren syndrome requires an injection of the anesthetic in the lip or in the front of the ear. You will have stitches where the tissue sample was removed.
This test is done to find the cause of abnormal lumps or growths of the salivary glands. It is also done to diagnose Sjogren syndrome.
The salivary gland tissue is normal.
