Nasal mucosal biopsyDefinition: 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.
Alternative Names: Biopsy - nasal mucosa; Nose biopsy
How the test is performed: 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: No special preparation is necessary. You may be asked to fast�for a few hours before the biopsy.
How the test will feel: 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.
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.
Normal Values: There is normal mucosal tissue, with no abnormal growths or tissues.
What abnormal results mean:
What the risks are: - Infection
- Bleeding from the biopsy site
Special considerations: Avoid blowing your nose after the biopsy.
