Your Napanee Invisalign® Provider
Wondering what will happen during your oral biopsy, and why you'd need one? Our dentists in Napanee explain this procedure and answer common questions about this dental surgery.
What is an oral biopsy?
During this surgical procedure, tissue is taken from the patient's oral cavity so it can be examined, typically so a diagnosis can be provided.
Why would an oral biopsy be recommended?
If you or your dentist notice a lesion that interferes with your oral function, you might require a biopsy to identify the cause so appropriate treatment can be prescribed. The oral cavity might be affected by inflammatory changes, or you may have bone lesions your dentist is unable to identify with X-rays or clinical examination.
A biopsy can also be conducted if your dentist suspects you have oral cancer (which may be found in the mouth, head and neck). If cancer has been diagnosed, a biopsy can help determine the stage and extent of the disease, in addition to its source.
Oral and maxillofacial surgeons diagnose and treat a range of illnesses and injuries affecting the neck, jaw, face and mouth. You may be referred to one of these professionals, who can thoroughly examine your head and neck and perform an oral biopsy. We may also refer you to a otolaryngoloist (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.
Types 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
Your surgeon will complete this type of biopsy 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 should I prepare for my oral biopsy?
You do not need to do much to prepare for a biopsy appointment. If the biopsy will be performed on part of a bone, your dentist will recommend x-rays or CT scans first, and ask that you not eat anything for a few hours before the biopsy.
Once you arrive, you’ll typically be asked to rinse with 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.
Is an oral biopsy painful?
You shouldn’t feel pain during the procedure – perhaps just a sharp pin prick or pinch as 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.
After anesthesia wears off, depending on where the biopsy was performed the site may feel sore for several 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 for bleeding).
If you experience significant pain from the biopsy, you may be prescribed pain medications.
