Nasendoscopy for laryngeal cancer

A nasendoscopy is a test to look at the:

  • inside of the nose
  • throat (pharynx)
  • voice box (larynx)

Your doctor passes a thin flexible tube called a nasendoscope into your nose and down the back of your throat to your voice box. The tube has a camera and a light at the end and allows the doctor to check for any abnormal looking areas.

Preparing for a nasendoscopy

There are no special preparations for a nasendoscopy. You can eat and drink and take your medicines as normal. 

What happens during a nasendoscopy?

A nasendoscopy usually takes place in an outpatient clinic. It lasts only a few minutes. You will be awake and able to speak to the doctor.

Your doctor passes the nasendoscope into your nose. This can be uncomfortable but does not usually hurt. Your eyes might water, and you might feel like coughing.

Your doctor might ask if you would like a local anaesthetic sprayed in the nose 10 minutes beforehand to numb it.

If your specialist sees an abnormality in your nose, you will probably need to go into hospital for a day to have an endoscopic biopsy under a short general anaesthetic.

What happens after a nasendoscopy?

You can usually go home straight after your test. 

If you had the anaesthetic spray, you can’t eat or drink until the anaesthetic wears off and your throat feels normal again. This may take about an hour.

Nasendoscopy is a very safe procedure but your nurse will tell you who to contact if you have any problems after your test. Your doctors will make sure the benefits of having a nasendoscopy outweigh these possible risks.

Getting your results

After the test, your doctor will explain to you their findings. They will tell you whether you need a biopsy under a general anaesthetic.
