Nasoendoscopy

Read about what nasoendoscopy for nasal and paranasal sinus cancers is, how you have it and what happens afterwards.

What it is

A nasoendoscopy is a test to look at the inside of the nose and throat.

Your doctor passes a thin flexible tube called a nasoendoscope up your nose and into your throat. The tube has a camera and a light at the end so the doctor can check for any abnormal looking areas.

Before your test

There are no special preparations for a nasoendoscopy.

You can eat and drink and take your medicines as normal. 

What happens

This normally takes place in an outpatient clinic. You will be awake and able to speak to the doctor.

Your doctor passes the nasendoscope up your nose and down your throat. This can be uncomfortable but does not usually hurt. Your doctor might ask if you would like an anaesthetic sprayed on the back of your throat beforehand to numb it.

After your test

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.

Nasoendoscopy is a very safe procedure but your nurse will tell you who to contact if you have any problems afterwards. Your doctors will make sure the benefits of having a nasoendoscopy outweigh any possible risks.

Getting your results

You should get your results within 1 or 2 weeks at a follow up appointment. 

Waiting for test results can be a very worrying time. You might have contact details for a specialist nurse who you can contact for information if you need to. It can help to talk to a close friend or relative about how you feel.

You can also contact the Cancer Research UK nurses on freephone 0808 800 4040 for information and support. The lines are open from 9am to 5pm, Monday to Friday.

Contact the doctor who arranged the test if you haven’t heard anything after a couple of weeks.

If your specialist sees an abnormality in your nose, you will probably need to go into hospital for a day to have a panendoscopy. The nasoendoscope is too fine to take samples of tissue (biopsies). But a panendoscope is thicker and your specialist can use it to take a biopsy of the abnormal area.
