What is a microlaryngoscopy?

A microlaryngoscopy is a surgical procedure that allows a provider to view your vocal cords (also called vocal folds) with a microscope. During this procedure, your provider may also remove lesions (growths) from your vocal folds or correct movement disorders of your larynx (voice box). Microlaryngoscopy can also reduce narrowing of your larynx and trachea (windpipe).

Why would I need a microlaryngoscopy?

Your healthcare provider will typically recommend microlaryngoscopy if they detect a lesion on your larynx. During this test, your provider can treat:

• Noncancerous vocal fold lesions, such as nodules, polyps or cysts.
• Vocal fold motion disorders such as vocal fold paralysis.
• Signs of laryngeal cancer.
• Subglottic stenosis.

How does a microlaryngoscopy work?

Microlaryngoscopy allows your provider to see your vocal folds without surgical incisions. Providers use small instruments that fit directly in your mouth and throat.

During the procedure, your provider uses a rigid tube that helps them view your larynx directly. This tube is large enough to put one or two instruments in without obstructing their view.

Using the light and microscope, your provider examines your vocal folds and looks for changes or growths. Your provider may also use surgical tools to remove growths, such as a small scalpel, scissors and graspers. During a laser microlaryngoscopy, your provider may use a laser to remove lesions or growths.

How do I prepare for a microlaryngoscopy?

Microlaryngoscopy requires general anesthesia. You will be asleep and won’t feel any discomfort during the procedure. To prepare for anesthesia and a microlaryngoscopy:

• Don’t smoke for at least one day before your procedure. For the most benefits, stop smoking for at least two weeks before your procedure and for two weeks after.
• Stop eating and drinking for at least eight hours before your procedure, unless your provider tells you otherwise.
• Tell your provider about all the medications you take, including vitamins and supplements. You may need to stop taking some or all of them several days before your microlaryngoscopy.
