Salivary gland biopsy
Salivary Gland Biopsy
A salivary gland biopsy is a common procedure performed for diagnostic evaluation of the salivary glands to follow-up on a suspected tumor. This procedure is used to identify and locate potential radiological abnormalities in the salivary glands and provide material for microscopic examination.
Preparation for a Salivary Gland Biopsy.
It is important to adequately prepare for a salivary gland biopsy. These steps should include:
- Informing the doctor of any medications that the patient is taking, both prescription and over-the-counter medications, as well as the use of herbal supplements.
- Reviewing any allergies that the patient may have, particularly allergies to local anesthetics.
- Avoiding smoking, drinking alcohol, and aspirin products for at least 24 hours prior to the procedure.
- The patient may be asked to fast overnight prior to the procedure.
- In some cases, antibiotics may be prescribed prior to the procedure to minimize the risk of infection.
Procedure for a Salivary Gland Biopsy.
Once the patient is adequately prepared for the salivary gland biopsy, the following steps are involved:
- The patient is positioned in a comfortable position.
- The area where the sample will be taken is cleaned with antiseptic.
- Local anesthetic is used to numb the area.
- A small biopsy needle is used to remove a sample of salivary gland tissue.
- The sample of tissue is sent for diagnostic evaluation and microscopic examination.
- The patient is monitored until the procedure is complete.
- Patient is advised to avoid strenuous activity for 24 hours.
Types of Salivary Gland Biopsies.
There are two main types of salivary gland biopsy:
- Core needle biopsy: This procedure uses a long, thin needle to remove a cylindrical tissue sample from the salivary gland.
- Fine needle aspiration biopsy: This procedure uses a shorter, thinner needle to remove individual cells from the salivary gland. This is useful for smaller masses or lesions that cannot be sampled with a core needle biopsy.
Risks and Complications of a Salivary Gland Biopsy.
The risks associated with a salivary gland biopsy are similar to those associated with any type of biopsy. These include:
- Bleeding
- Infection
- Scarring
- Damage to surrounding structures
- Pain at the biopsy site
- Nerve damage
Why is a Salivary Gland Biopsy Performed?
A salivary gland biopsy is usually performed to:
- Diagnose a tumor or other abnormality in the salivary gland
- Identify an infection of the salivary gland
- Evaluate the extent of a tumor in the salivary gland
- Exclude malignancy.
When is a Salivary Gland Biopsy Necessary?
A salivary gland biopsy may be necessary in the following situations:
- Suspicion of a tumor in the salivary gland
- Persistent swelling of the salivary gland
- Suspected infection or inflammation of the salivary gland
- A biopsy is also commonly performed to evaluate abnormal changes seen on imaging studies, such as an ultrasound or CT scan.
