Your doctor may suggest that you have an EUA if they:
- see anything unusual
- cannot see the area clearly with a nasendoscope.
This allows them to look at the area more closely using an endoscope. An endoscope is a thin, flexible tube with a camera and a light at the end.
When you are asleep under the anaesthetic, your doctor passes the endoscope down your throat. They can use the camera or attach a microscope to the end of the tube to closely look at the area.
During the examination, the doctor can take samples from any areas that look abnormal. This is called a biopsy. You can usually have this test in a day surgery unit. Most people can go home the same day.
