Oropharyngeal biopsy

Throat anatomy

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

Throat lesion biopsy; Biopsy - mouth or throat; Mouth lesion biopsy

A pain-killer or numbing agent is usually used on the area. For large sores or sores of the throat, a general anesthetic that puts the patient to sleep may be needed. The entire lesion, or a small portion of larger lesions, is removed and sent to the laboratory to check for problems. If there is a growth in the mouth or throat, the biopsy may be the first part of tumor removal.

If a simple pain-killer or numbing agent is to be used, there is no special preparation. If the test is part of a tumor removal or if general anesthetic is to be used, you may be told not to eat for 6 - 8 hours before the test.

There may feelings of pressure or tugging during removal of the tissue. If there is bleeding, cautery (sealing of blood vessels with electric current or laser) may be needed. After the numbness wears off, the area may be sore for a few days.

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