Laryngoscopy for throat cancer
For both of these procedures, your doctor may spray the back of your throat with a numbing medicine to avoid pain. Because people diagnosed with laryngeal cancer are also at increased risk for other head and neck cancers, your doctor will also examine the nasopharynx (the top portion of the throat, behind the nose), mouth, tongue and neck.
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.
