See Your Vocal Cords in Action—Through a Camera!

Fiber Optic Laryngoscopy is a medical procedure that uses a special tool called a flexible laryngoscope. This instrument is a thin, flexible tube equipped with a small camera, light, and lens at the tip. Through this tool, doctors can directly view the internal condition of the larynx, vocal cords, and other areas of the throat in detail.

How is the FOL procedure performed?

This procedure is usually done in a clinic or hospital in Surabaya without requiring hospitalization. Before the examination, your nose and throat will be sprayed with a local anesthetic to minimize discomfort and the gag reflex. The laryngoscope is then carefully inserted through the nose and gently guided into the throat until it reaches the larynx and vocal cords. During the process, the doctor may ask you to make sounds or perform specific swallowing movements to observe how the vocal cords move. Typically, this procedure does not take a long time.

What is the purpose of the FOL examination?

1.To observe the condition of the vocal cords

This is the primary function. The doctor can clearly see how the vocal cords move when you speak, sing, or even whisper. This helps identify structural or functional abnormalities.

2.To detect the cause of voice disorders

If you experience hoarseness, voice loss, a weak voice, or other voice changes lasting more than a few weeks, FOL can help determine the cause, such as:

• Inflammation or Laryngitis: Swelling or irritation of the vocal cords.
• Vocal Cord Nodules, Polyps, or Cysts: Benign growths that may interfere with normal vibration.
• Vocal Cord Paralysis: A condition where one or both vocal cords do not move properly, often caused by nerve damage.
• Laryngopharyngeal Reflux (LPR): A condition where stomach acid travels up to the larynx and causes irritation.

3.To look for masses or abnormal growths

FOL is used to examine any lumps, tumors, or other suspicious areas in and around the larynx that could be early signs of laryngeal cancer.

4.To take tissue samples for biopsy

If a suspicious area is found, the doctor can take a small tissue sample using the laryngoscope for further examination in a laboratory (biopsy) to confirm a diagnosis.

5.To evaluate swallowing difficulties

Sometimes, issues in the larynx or vocal cords can affect swallowing. FOL helps assess swallowing function and detect any blockages or abnormalities.

6.To monitor patients with chronic conditions

For patients with chronic laryngeal conditions or those recovering after surgery, FOL can be used to monitor progress and treatment effectiveness.

What are the advantages of the FOL procedure?

• More precise and detailed examination
• Direct and real-time visualization on a monitor
• Minimally painful and comfortable for patients
• Can more accurately detect infections, anatomical abnormalities, or blockages

Overall, Fiber Optic Laryngoscopy (FOL) is a safe diagnostic tool for examining the throat area. This procedure allows doctors to get a clear view of the condition of the larynx and vocal cords, enabling accurate diagnosis and appropriate treatment planning to restore your voice quality and throat health.

If you have any issues related to the throat area, consult the ENT medical team at National Hospital Surabaya immediately.
