Nasal mucosal biopsy

What is Nasal Mucosal Biopsy?

Nasal mucosal biopsy, also known as nasal brushing or nasal endoscopy, is a procedure used to obtain samples of cells from the lining of the nose. It is used to diagnose a variety of nasal and sinus conditions, including chronic inflammation, tumor formation, and underlying infections.

Preparing for a Nasal Mucosal Biopsy

Before having a nasal mucosal biopsy, it is important to discuss any allergies or chronic conditions with your physician. Your doctor will also give you instructions on how to prepare for the procedure. In most cases, no specific preparation is needed. It is important, however, to avoid taking any medications that may thin the blood or increase the risk of bleeding.

Procedure

During the procedure, a thin, flexible tube (endoscope) is inserted into the nose to get a better view of the inside of the nasal cavity. The physician then uses a small brush or forceps to obtain a sample of cells from the lining of the nose. The sample is then sent to the laboratory for analysis.

Types of Nasal Mucosal Biopsy

There are two types of nasal mucosal biopsy:
  • Bronchial lavage: This type of biopsy involves flushing a saline solution into the nose to collect cells from the mucosa.
  • Biopsy forceps: This type of biopsy involves scraping the mucosal lining of the nose with a special tool called a biopsy forceps.

Risks of Nasal Mucosal Biopsy:

Nasal mucosal biopsy is generally a safe and well-tolerated procedure. However, like any medical procedure, it is associated with certain risks and complications. These include bleeding, infection, and irritation of the nasal lining.

Why is a Nasal Mucosal Biopsy Performed?

A nasal mucosal biopsy is performed to diagnose a variety of nasal and sinus conditions, including chronic inflammation, tumor formation, and underlying infections. It can also help to determine the cause of nasal symptoms such as persistent nasal discharge or obstruction.

When is a Nasal Mucosal Biopsy Indicated?

A nasal mucosal biopsy is indicated when other diagnostic tests, such as imaging studies and laboratory tests, have failed to identify a diagnosis. It can also be used to confirm or rule out a suspected diagnosis.
