What is Laryngoscopy?

Laryngoscopy is the visual exam of the voice box (larynx) and the vocal cords. There are two main kinds:

Indirect laryngoscopy—uses mirrors to examine the larynx and hypopharynx (a portion of the passageway to the lungs and stomach)

Direct laryngoscopy—uses a special instrument, most often a flexible scope

Both are usually done in the office.

Laryngoscopy is used to examine and diagnose problems inside the throat. It is most often done:

  • To diagnose the cause of a persistent cough, bloody cough, hoarseness, throat pain, or bad breath
  • To evaluate reasons for difficulty swallowing
  • To evaluate a possible cause for persistent earache
  • To remove a foreign object
  • To visualize a mass in the throat

Possible Complications

If you are planning to have a laryngoscopy, your doctor will review a list of possible complications, which may include:

  • Pain
  • Vomiting and gagging
  • Excessive swelling or bleeding
  • Cuts on the bottom of the tongue from stretching it over the teeth
  • Bleeding from the nose if the scope is passed through the nose
  • Anesthesia-related problems

  • Increasing pain
  • Coughing up, spitting out, or vomiting blood
  • Difficulty breathing or swallowing
