A nasal endoscopy is a diagnostic procedure that involves inserting a thin, flexible tube with a camera and light source (called an endoscope) through the nostril to examine the nasal passages and the sinuses.
While a nasal endoscopy is primarily focused on examining the nasal passages and sinuses, it can provide some visualization of the back of the throat and the entrance to the voice box (larynx). However, the view of the throat is limited and not as detailed as what can be seen with a separate throat endoscopy, also called a laryngoscopy.
A laryngoscopy involves inserting a similar type of endoscope through the mouth or nose to visualize the throat and vocal cords. This allows for a more comprehensive examination of the structures in the throat, including the vocal cords, tonsils, and pharynx.
In summary, while a nasal endoscopy may provide some visualization of the back of the throat, it is not a substitute for a separate laryngoscopy if a more detailed examination of the throat is required.
