NASAL ENDOSCOPY

Definition

A Nasal Endoscopy is a procedure done using a tube which is flexible known as endoscope to reach the areas of the nasal passage i.e. the Larynx, Oropharynx and Nasopharynx. You can see the drainage pathways for the sinuses, as well as the back of the nose.

In other words, this is a procedure which involves inserting a tiny camera into the nose in order to look at blood vessels and nasal structures.

This procedure is usually conducted by ear, nose, and throat (ENT) specialists or allergists. Nasal Endoscopy is also known as rhinolaryngoscopy or rhinoscopy or rhinopharyngoscopy.

WHY IT IS DONE

A Nasal Endoscopy helps the doctor:-

• To have a direct observation of the nasal passages, larynx, pharynx, and other surrounding areas.
• It can diagnose breathing disorders and internal bleeding.
• To diagnose problems such as nasal polyps, sinusitis, nasal blockage and laryngeal trauma.
• The nasal endoscopy diagnoses whether it is sinus or a nasal disease in its entirety.
• Endoscopes are also helpful in the diagnosis and treatment for cancer.
• To find the effects of conditions of severe allergies, deficiencies and mucociliary disorders
• To find whether there is a nasal obstruction in the naval cavity.
• To find a reason for facial pain or head ache.

HOW IT IS DONE

The patient has to sit in a comfortable chair with head support. An anesthetic liquid or spray is applied to the patient’s throat area.

After the area is numb, the doctor threads a flexible fiber-optic tube called endoscope or metal telescope, through the nasal passage as far as the vocal cords in the throat.

Then the doctor observes internal areas as the endoscope is introduced and withdrawn. The examination will take about 5 to 10 minutes.

After removing the endoscope, the patient can start his normal activities immediately. If a topical or local anesthetic is used during the examination, it will last for about 30 minutes. You can eat or drink, once the numbness is gone.

RISKS

A Nasal Endoscopy is generally a normal and safe procedure, it’s a quick and easy way to view. But the Endoscopy only diagnoses, it cannot provide treatment. However, there could be possibility of infection in the part where endoscopy was done, tearing of organ, excessive bleeding or allergies due to anesthesia.
