What happens during a larynx diagnostic endoscopy?

A diagnostic endoscopy of the larynx takes between 15-20 minutes. Local anaesthetic will be applied to your nose. Your consultant will pass a very thin, flexible tube with a light and camera on the end (a nasendoscope) through your nose to the area just above your throat. The camera will send pictures of your larynx to a monitor.

If any abnormality is found they may take a tiny tissue sample to be examined in a laboratory.

After larynx diagnostic endoscopy

You will be able to go home after your endoscopy. The numb feeling in your throat should ease after about 1 hour. Avoid drinking any hot drinks until all the feeling in your throat has returned.

Be sure and ask your consultant when the results of your endoscopy will be available.
