Video of your vocal cords

This test uses a long, flexible tube called an endoscope to examine your larynx and vocal cords while you speak.

It’s sometimes called a videostroboscopy, or videolaryngoscopy with stroboscopy.

What happens

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

They pass a thin flexible tube called an endoscope either up your nose or down your throat. This tube has a camera and fibre optic strobe light on the end, which your doctor uses to make a video of your vocal cords

Your doctor then asks you to talk, and makes the video. This allows them to see your vocal cords moving in slow motion, and gives a clear picture of the area.

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 worrying time. You can contact your specialist nurse if you’re finding it hard to cope. It can also help to talk to a close friend or relative about how you feel.

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

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