What is a laryngoscopy?
A laryngoscopy is often used to examine the back of the throat. The two types of laryngoscopy are indirect laryngoscopy and direct laryngoscopy.
During an indirect laryngoscopy,we place small mirrors at the back of your mouth to clearly examine your throat, the base of your tongue and part of your larynx.
During a direct laryngoscopy, your doctor may use a fiber-optic laryngoscope, which is a thin, flexible, lighted tube that is inserted through the mouth or nose, to view the larynx and surrounding areas.
For both of these procedures, your doctor may spray the back of your throat with a numbing medicine to avoid pain.
Laryngoscopy for thyroid cancer
Because the thyroid gland is so close to the vocal cords, thyroid tumors may sometimes affect them. For this reason, your doctor may want to examine the cords first with special tools, such as a laryngoscope, if you are scheduled for surgery.
