Laryngeal Videostroboscopy

What is a laryngovideostroboscopy?

Laryngeal videostroboscopy (also known as laryngovideostroboscopy or video strobe laryngoscopy) is an important diagnostic tool that allows an ear, nose and throat (ENT) specialist to view the vocal cords in your larynx (voice box) in slow motion.

It uses a stroboscopic lamp, which gives out regular flashes of light. Either a rigid endoscope through the mouth or a flexible endoscope through the nose may be used to visualise the voice box after applying local anaesthetic.

Video pictures are then recorded while the patient is talking, singing or whistling and studied by the specialist.

Why do you need a laryngeal videostroboscopy?

A laryngeal videostroboscopy is used to diagnose voice disorders. These include:

  • Chronic laryngitis, which is inflammation of the vocal cords that last for more than 3 weeks.
  • Hoarseness, which can be due to overuse, polyps, acid reflux or other reasons.
  • Globus sensation, or the feeling of a lump in the throat.

During the procedure, your doctor will assess the situation and decide whether voice therapy, surgery or a watch-and-wait approach will be needed.

What are the risks and complications of a laryngeal videostroboscopy?

Problems are rare, but some complications that may arise from a laryngeal videostroboscopy include:

  • Bleeding
  • Gagging or vomiting
