Video of your throat and larynx

In this test the doctor uses a long, flexible tube called an endoscope to make a video of the inside of your throat and larynx. The test is called a transnasal oesophagoscopy.

Why you have it

You might have this test instead of having an endoscopy. This might happen if you aren't well enough to have an endoscopy under a general anaesthetic.

How you have it

You have this test at a hospital as an outpatient. The test takes about 30 minutes.

Your doctor passes the endoscope up your nose. The tip of the endoscope tube has a digital video system and self contained light. This gives your doctor clear pictures of the inside of the throat and larynx.

What happens

Your doctor uses an anaesthetic spray to numb your throat. It takes a few minutes for the area to go numb.

The doctor passes a long, flexible tube called an endoscope up your nose. It can feel uncomfortable but shouldn’t be painful.

Your doctor looks at all your upper air passages, including the larynx, from above. They check for any growths or abnormal looking areas.

Getting your results

Your scan will be looked at by a specialist doctor and you should get your results within 1 or 2 weeks. You won't get any results at the time of the scan. 

Waiting for test results can make you anxious. Ask your doctor or nurse how long it will take to get them. Contact them if you haven’t heard anything after a couple of weeks.
