Nasopharyngoscopy is a common and minimally invasive procedure used to examine the inside of the nose, nasal passages, and the upper part of the throat behind the nose. It is performed using a thin, flexible tube with a light and camera at the tip, called a nasopharyngoscope. This allows the doctor to see areas that cannot be examined with a simple torch or mirror.
The procedure is widely used in ENT practice to evaluate symptoms such as nasal blockage, chronic sinus problems, recurrent nosebleeds, loss of smell, voice changes, throat discomfort, swallowing difficulty, ear problems, and suspected growths in the nose or throat. It is also used to check the vocal cords, adenoids, and the back of the throat in patients with persistent cough, hoarseness, or breathing issues.
What is Nasopharyngoscopy?
Nasopharyngoscopy is a diagnostic procedure in which an ENT specialist uses a thin, flexible endoscope to examine the nasal cavity, nasopharynx, and surrounding structures. The endoscope is passed gently through the nostril and advanced to visualize the nasal passages, sinuses drainage pathways, adenoids, back of the nose, and the upper part of the throat.
The procedure is usually done in the outpatient setting. It takes only a few minutes and does not require general anesthesia in most cases. A local anesthetic spray or gel may be used to numb the nose and reduce discomfort. The doctor watches the images on a monitor while guiding the scope carefully.
Nasopharyngoscopy is different from rigid nasal endoscopy, which uses a straight, rigid scope. The flexible nasopharyngoscope can bend and reach areas that are difficult to see with a rigid scope, making it useful for examining the voice box and upper airway as well.
