Definition Return to top

A nasal mucosal biopsy is surgery in which a small piece of tissue is removed from the lining of the nose and checked for disease.

How the Test is Performed Return to top

A pain-killer 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 Return to top

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

How the Test Will Feel Return to top

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