Laryngoscopy is an examination that lets your doctor look at the back of your throat, your voice box, and vocal cords with a scope. There are two types of laryngoscopy which are indirect and direct fiber-optic Laryngoscopy. In indirect Laryngoscopy there is a small mirror which is used to look at the back of the throat while light reflects back. Direct Laryngoscopy lets your doctor see deeper into your throat. The scope is either flexible or rigid.

The nasal endoscope is a medical device consisting of a thin, rigid tube with fiber optic cables for bringing in light. Typically, nasal endoscopy is performed with a 30 degree endoscope using the “three pass” technique, visualizing three main areas in the nasal and sinus cavities.
Otoendoscopy is the endoscopy of the ear which involves placing a rigid endoscope into the ear to examine both the exterior and middle portions of the ear. The intact eardrum can be examined closely and the movement of the ear drum evaluated. It visualizes the whole tympanic membrane and the ear canal without having to manipulate the patient’s head or the microscope and also the structures from multiple angles as opposed to the microscope’s single axis along the ear canal.
