Oropharynx lesion biopsy

Definition

An oropharynx lesion biopsy is surgery in which tissue from an abnormal growth or mouth sore is removed and checked for disease.

How the Test is Performed

Painkilling or numbing medicine is first applied to the area. For large sores or sores of the throat, general anesthesia may be needed. This means you will be asleep during the procedure.

All or part of the problem area (lesion) is removed. It is sent to the laboratory to check for diseases. If a growth in the mouth or throat needs to be removed, the biopsy will be done first. This is followed by the actual removal of the growth.

How to Prepare for the Test

If a simple painkilling or local numbing medicine is to be used, there is no special preparation. If the test is part of a growth removal or if general anesthesia is used, you will likely be asked not to eat for 6 to 8 hours before the test.

How the Test will Feel

You may feel pressure or tugging while the tissue is being removed. After the numbness wears off, the area may be sore for a few days.

Why the Test is Performed

This test is done to determine the cause of a sore (lesion) in the throat.

Normal Results

This test is only done when there is an abnormal tissue area.

What Abnormal Results Mean

Abnormal results may mean:

• Cancer (such as squamous cell carcinoma)

• Benign lesions (such as papilloma)

• Fungal infections (such as candida)

• Histoplasmosis

• Oral lichen planus

• Precancerous sore (leukoplakia)

• Viral infections (such as Herpes simplex)

Risks

Risks of the procedure may include:

• Infection of the site

• Bleeding at the site

If there is bleeding, the blood vessels may be sealed (cauterized) with an electric current or laser.

Considerations

Avoid hot or spicy food after the biopsy.
