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.
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.
