Fiberoptic Laryngoscopy

Fiberoptic laryngoscopy is a diagnostic test that uses a thin tube with a light source and camera attached at its tip to help the doctor inspect your throat for problems. The procedure is performed to examine the back of the throat and vocal cords.

Laryngoscopy is indicated to help diagnose conditions from symptoms such as chronic cough, coughing blood, difficulty in swallowing, bad breath which does not subside, respiratory tract problems in smokers, persistent throat pain and voice problems such as weak voice, no voice or hoarseness which persists for more than 3 weeks. The procedure can also be used to extract a tissue sample or biopsy from the throat for further examination or to remove an object which is blocking the airway.

You will be instructed not to eat anything 6 to 12 hours prior to the procedure. Fiberoptic laryngoscopy involves the use of a small flexible telescope passed through the nose and into the throat. Your throat and back of your nose is first numbed with a spray to make you comfortable and reduce your gag reflex. The tube is slowly passed through the nose and throat as your doctor examines structures and obtains pictures with the camera. The entire procedure takes only a few minutes.

Following the procedure, you will usually be discharged home the same day. Your throat may be sore and you may have some difficulty swallowing, but you will be able to resume your usual diet and activities.

Fiberoptic laryngoscopy is generally a safe technique, but may rarely be associated with risks and complications such as injuries to the nose, mouth or throat, vocal cord spasms, nose bleeds, infections or adverse reaction to the anesthetic agent.
