Why would my dentist recommend an oral biopsy?

In this post, our Midland dentists talk about oral biopsies, including when you may need one and what you can expect from your biopsy.

Oral Biopsies

An oral biopsy is a surgical procedure where tissue is taken from a patient’s oral cavity to be examined, this is often done to help make a diagnosis.

When Your Dentist Will Recommend an Oral Biopsy

If you have a lesion that interferes with your oral function, you may need a biopsy to determine the cause so proper treatment can be prescribed. There may also be inflammatory changes affecting the oral cavity or bone lesions your dentist is unable to identify with X-rays or clinical examination.

A biopsy can also be performed if your dentist suspects you have oral cancer (which is found in the mouth, head, and neck). If cancer has already been diagnosed, a biopsy can help determine the stage and extent of cancer, as well as its source.

Oral and maxillofacial surgeons diagnose and treat a range of illnesses and injuries affecting the neck, jaw, face, and mouth. During your appointment, a thorough exam of your head and neck will be done and an oral biopsy performed. You may also be referred to an otolaryngologist (an ear, nose, and throat doctor).

During an oral biopsy, a small sample of the suspicious tissue will be removed from your oropharynx or mouth and sent to a pathologist, where it will be checked for disease. A custom treatment plan will then be developed based on information in the pathologist’s report.

Different Kinds of Oral Biopsies

The 6 types of oral biopsies include:

Aspiration Biopsy

A needle and syringe are used to remove a sample of cells or contents from a lesion. If the oral surgeon is not able to drain fluid or air, it may mean the lesion is solid.

Brush Biopsy

The surgeon applies firm pressure with a circular brush, rotating it to pick up cellular material that will later be transferred to a glass slide, preserved, and dried.

Cytology

This type of oral biopsy aids in the diagnosis of lesions in the oral cavity. These lesions may be caused by infections, herpes, or post-radiation changes.

Though individual cells can be examined, an accurate and definitive diagnosis may not be possible without an excisional or incisional biopsy also being performed.

Excisional Biopsy

Performed for small oral lesions (typically measuring less than 1 cm) that appear benign during a clinical exam, an excisional biopsy completely removes the lesion.

Incisional Biopsy

This type of biopsy is completed in order to obtain a representative sample of the oral lesion. If your oral lesion is large or has differing characteristics, more than one area may need to be sampled.

Punch Biopsy

Best suited for diagnosing oral manifestations of ulcerative and mucocutaneous conditions of the oral cavity (such as lichen planus), a punch biopsy is completed using a punch tool.

How To Prepare for Oral Biopsies

You do not need to do much to prepare for a biopsy appointment. If the biopsy will be performed on part of a bone,  X-rays or CT scans will be recommended first, and you will be asked not to eat anything for a few hours before the biopsy.

Once you arrive, you’ll typically be asked to rinse with an antibacterial mouthwash. Local anesthesia is usually used and you will likely be awake for the procedure. However, you may be provided general anesthesia if the lesion is in an area of the mouth that’s hard to reach.

Will My Oral Biopsy Be Painful?

You shouldn’t feel pain during the procedure – perhaps just a sharp pinprick or pinch as a local anesthetic is injected, or as the needle is used to take the biopsy. The use of instruments may also result in some minor pressure as the sample is collected.

Once the anesthesia wears off, depending on where the biopsy was conducted the site might feel sore for a few days. You may want to stick to soft foods and take over-the-counter medication for pain (avoid taking NSAIDs, which can increase the risk of bleeding).

If you experience significant pain from the biopsy, you may be prescribed pain medications.
