Nasendoscopy is a way of looking at your soft palate (roof of the mouth) and throat. It is used to find out the cause of voice problems, swallowing difficulties, and throat and ear pain. It can also be used to check for injuries to your throat, narrowing of your throat (strictures), or blockages in your airway.
Nasendoscopy is an outpatient procedure. It involves using a thin, flexible tube with a very small telescope at the end, which is gently passed up your nose and down into your throat. Before the test you may be given a local anaesthetic lozenge or spray to numb the back of your throat.
The telescope is linked to a video camera and the pictures can be seen on a monitor. This lets the consultant see your throat and voice box. You might find this a bit uncomfortable, but it only takes a few minutes. The procedure is exactly the same whether you are a child or an adult. Most children and young people manage it without difficulty.
What are the risks?
The risks involved in Nasendoscopy are very small. In very rare cases there might be a reaction to the local anaesthetic. Also, there may be a little bleeding if the tube scratches the inner lining of your nose, but this is very uncommon.
Ask your consultant to explain how any risks might apply to you.
