Nasal mucosal biopsy - Overview

Alternative Names

Biopsy - nasal mucosa; Nose biopsy

Definition of Nasal mucosal biopsy:

A nasal mucosal biopsy is the removal of a small piece of tissue from the lining of the nose so that it can be checked for disease.

How the test is performed:

A painkiller is sprayed into the nose. In some cases, a numbing shot may be used. A small piece of the tissue that appears abnormal is removed and checked for problems in the laboratory.

How to prepare for the test:

No special preparation is necessary. You may be asked to fast for a few hours before the biopsy.

How the test will feel:

You may feel pressure or tugging when the tissue is removed. After the numbness wears off, the area may be sore for a few days. A small to moderate amount of bleeding after the procedure is common. If there is bleeding, the blood vessels may be sealed with an electric current or laser.

Why the test is performed:

Nasal mucosal biopsy is usually done when abnormal tissue is seen during examination of the nose. It may also be done when problems affecting the mucosal tissue of the nose are suspected.
