Oropharynx lesion biopsy

Alternative names:

biopsy of the mouth or throat; mouth lesion biopsy; throat lesion biopsy

How the test is performed:

A topical anesthetic is usually used (for large lesions or lesions of the throat, a general anesthetic may be needed). The entire lesion, or a small portion of larger lesions, is removed and sent to the laboratory for analysis. If a growth is present in the mouth or throat, this test may be part of tumor removal/resection.

How to prepare for the test:

If a local or topical anesthetic is to be used, there is no special preparation. If the test is to be part of a tumor removal or if general anesthetic is to be used, fasting for 6 to 8 hours may be necessary.

Infants and children:
The physical and psychological preparation you can provide for this or any test or procedure depends on your child's age, interests, previous experience, and level of trust. For specific information regarding how you can prepare your child, see the following topics as they correspond to your child's age:

• infant test or procedure preparation (birth to 1 year)
• toddler test or procedure preparation (1 to 3 years)
• preschooler test or procedure preparation (3 to 6 years)
• schoolage test or procedure preparation (6 to 12 years)
• adolescent test or procedure preparation (12 to 18 years)

How the test will feel:

After the anesthetic wears off, the area may be tender or sore for a few days.

Why the test is performed:

This test is performed to determine the specific cause of a lesion in the mouth.
