Pharyngoscopy 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 pharyngeal cancer are also at increased risk for other head and neck cancers, your doctor will also examine the mouth, tongue and neck.
What is a pharyngoscopy?
A pharyngoscopy is often used to examine the back of the throat. The two types of pharyngoscopy are indirect pharyngoscopy and direct pharyngoscopy.
During an indirect pharyngoscopy your doctor places small mirrors at the back of your mouth to clearly examine your throat, the base of your tongue and part of your larynx.
A direct pharyngoscopy involves a fiber optic source that uses a flexible, lighted, narrow tube that may be inserted into the mouth or nose so that your doctor can examine hard-to-see areas such as the larynx and behind the nose.
