Biopsy – salivary gland
Salivary gland biopsy is the removal of cells or a piece of tissue from a salivary gland for the exam. One type of salivary gland biopsy is a needle biopsy. The skin or mucous membrane 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 is removed and placed on slides.
How the Test is Performed
You have several pairs of salivary glands that drain into your mouth:
- A major pair in front of the ears (parotid glands)
- Another major pair beneath your jaw (submandibular glands)
- Two major pairs on the floor of the mouth (sublingual glands)
- Hundreds to thousands of minor salivary glands in the lips, cheeks, and tongue
One type of salivary gland biopsy is a needle biopsy.
- The skin or mucous membrane 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 is removed and placed on slides.
- The samples are sent to the lab to be examined.
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.
An open surgical biopsy of the glands in the lips or the parotid gland can also be performed to diagnose diseases such as Sjogren syndrome .
How to Prepare for the Test
There is no special preparation for a needle biopsy. However, 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.
How the Test will Feel
With a needle biopsy, you may feel some stinging or burning if a local 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.
Why the Test is Performed
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.
Normal Results
The salivary gland tissue is normal.
What Abnormal Results Mean
Abnormal results may indicate:
- Salivary gland tumors or infection
- Sjogren syndrome
Risks
Risks from this procedure include:
- Allergic reaction to the anesthetic
- Bleeding
- Infection
- Injury to the facial or trigeminal nerve (rare)
- Numbness of the lip
FAQ
What does a salivary gland biopsy show?
- The primary pathological finding in SS is of lymphocytic infiltration of affected tissues. Salivary gland biopsies show focal aggregates of lymphocytes, plasma cells, and macrophages; there may be larger foci with the appearance of germinal centers. This appearance is characteristic of chronic lymphocytic sialadenitis.
Should I agree to a salivary gland biopsy for Sjogren’s syndrome?
- In patients who lack evidence for systemic autoimmunity, such as the relevant autoantibodies or concomitant autoimmune diseases (see ‘Diagnostic criteria’ above), labial salivary gland biopsy is essential to confirm the diagnosis.Apr 29, 2021
How long does it take to recover from salivary gland surgery?
Your Recovery
- A saliva duct is a tube that carries saliva from the gland into the mouth. The area below your jaw may be sore for several days after your surgery. The area also may be slightly swollen or bruised. It will probably take 1 to 2 weeks for the cut (incision) to heal.
How long does it take to get results from a salivary gland biopsy?
- You should get your results within 1 or 2 weeks at a follow up appointment.
How fast do salivary gland tumors grow?
- Grade 1 (low-grade) cancers have the best chance of being cured. They grow slowly and don’t look much different than normal cells. Grade 2 cancers grow moderately fast. Grade 3 cancers grow quickly.
What does a biopsy sample consist of?
- A biopsy is a medical procedure that involves taking a small sample of tissue so that it can be examined under a microscope. A tissue sample can be taken from almost anywhere on, or in the body, including the skin, stomach, kidneys, liver and lungs.
How painful is a salivary gland biopsy?
- With a needle biopsy, you may feel some stinging or burning if a local 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.
How is a salivary gland biopsy done?
- A local anesthetic is then injected to kill the pain. Once the site is numb, a fine needle is inserted into the salivary gland and a small piece of tissue is carefully removed. The tissue is placed on microscopic slides, which are then sent to the laboratory to be examined.
Is salivary gland surgery painful?
- There may be mild soreness inside the mouth where the duct was dilated. Most patients can return to work/school the following day. Avoid any strenuous activity, exercise, lifting more than 10 pounds, excessive bending or straining for 1-2 weeks following surgery to prevent bleeding.
Do benign salivary gland tumors need to be removed?
Treatment of Salivary Gland Tumors
- If you have a benign tumor, your doctor may recommend surgical removal to prevent it from becoming malignant over time. A benign tumor in the parotid gland can be removed using a surgical procedure called a partial superficial parotidectomy.
What type of doctor removes salivary glands?
- More commonly known as ear, nose and throat physicians (ENTs), Northwestern Medicine otolaryngologists specialize in the diagnosis, treatment and rehabilitation of diseases and disorders of the head and neck, including salivary gland disease.
What is a labial gland biopsy?
- Sjögren’s syndrome is characterized by chronic inflammation of the glands that produce saliva and tears. An important method for establishing the diagnosis is to take a biopsy of the salivary glands in order to determine whether inflammation is present, and if so, its type and severity.
What percentage of salivary gland tumors are malignant?
- About 80 percent of salivary gland tumors start in these glands. About 75 percent of these tumors are benign (usually a type called pleomorphic adenomas) and 25 percent are malignant.
What is the most common benign salivary gland tumor?
- Pleomorphic adenoma (PA) is the most common benign tumor of major or minor salivary glands.
What do salivary gland tumors feel like?
- A lump or swelling on or near your jaw or in your neck or mouth. Numbness in part of your face. Muscle weakness on one side of your face. Persistent pain in the area of a salivary gland.
What happens if a biopsy is positive?
- Generally, after a patient receives positive melanoma results, his or her doctors will need to proceed with staging the malignancy— which essentially means determining the extent of the cancer—and developing a treatment plan based on how far the cancer has progressed.
How long does it take to get biopsy results?
- A result can often be given within 2 to 3 days after the biopsy. A result that requires a more complicated analysis can take 7 to 10 days. Ask your doctor how you will receive the biopsy results and who will explain them to you.
What should you not do before a biopsy?
- Pre-Procedure Information: Do not take aspirin or aspirin products 7 days before the biopsy. Do not take blood thinning products 7 days before the biopsy. Do not take anti-inflammatory products 7 days before the biopsy. Do not take Vitamin E products 7 days before the biopsy.
How common are salivary gland tumors?
- Salivary gland cancers are not very common, making up 6% to 8% of all head and neck cancers in the United States. There are about 2,000 to 2,500 cases in the US each year. They occur at a rate of about 3 cases per 100,000 people per year in the Western world.
What is a minor salivary gland biopsy?
- Minor Salivary Gland (MSG) Biopsy. Minor salivary gland (MSG) biopsy of the lower lip mucosa is used to confirm the diagnosis of Sjogren’s syndrome. Sjogren’s is a chronic autoimmune disorder involving the destruction of glandular tissue.
Can you live without salivary glands?
- Sublingual glands are located under the tongue and the submandibular glands are beneath the jaw. Without these crucial salivary glands, the mouth would not be able to maintain tooth health nor moisture of any kind.
What happens if your salivary glands are removed?
- Nerve damage is possible. There are three nerves that lie close to the submandibular gland and can be damaged during its removal. Most nerve damage occurs as a result of bruising of the nerves while they are held out of the way and protected during surgery.
Can salivary gland affect eyes?
- Dry mouth, tooth decay, mouth sores, enlarged salivary glands, sialoliths and recurrent salivary gland infections are possible symptoms. The syndrome also effects moisture in the eyes, which might cause chronic eye infections, corneal ulcers and vision loss.
What is the most common malignant salivary gland tumor?
- Mucoepidermoid carcinoma is the most common type of salivary gland cancer. More than 30 percent of salivary gland cancers are thought to be this type. Cancers that develop here often form tiny mucous-filled cysts. Most mucoepidermoid carcinomas develop in the parotid glands.
What are symptoms of salivary gland problems?
- When there is a problem with the salivary glands or ducts, you may have symptoms such as salivary gland swelling, dry mouth, pain, fever, and foul-tasting drainage into the mouth.
What is the best treatment for salivary gland?
- Treatment for salivary gland tumors is usually with surgery to remove the tumor. People with salivary gland cancers may need additional treatments, such as with radiation therapy and chemotherapy.
