Diagnostic Nasolaryngopharyngoscopy

A Diagnostic Nasolaryngopharyngoscopy is a procedure used to diagnose conditions concerning the Nose and Throat. Once an examination has been made your consultant will then have an idea of the patient’s condition.

Symptoms a nasolaryngopharyngoscopy is used to investigate includes:
  • Blockage in the nose
  • Catarrh (build up of mucus in the nose)
  • Sore throat
  • Neck Lumps
  • Hoarse voice
  • Swallowing issues
  • Lumps in the throat
  • Coughing issues

By using this method of diagnostics your ENT specialist will be able to see a clear and close up view of the areas hard to see in the nose and throat as the scope being used is flexible.

Vocal chords can also be examined and the illumination of the scope will allow for a much better diagnosis for the patient.


Before the procedure begins your consultant will numb the throat by using a local anaesthetic spray on your nose to prevent gagging. The anaesthetic may taste bitter and make your throat tighten slightly, which is a sign the numbing is taking effect and the procedure can begin.

The scope will then be gently passed into one or both nostrils and into your throat. Whilst this is happening it is recommended to be still, relax and breathe through your mouth. Your consultant may ask you to sing a note, puff your cheeks out or stick your tongue out, however this will be explained during the procedure.


Your consultant normally can obtain your diagnosis within the same day therefore you should be aware of the outcome of your test after the procedure. It is recommended to not have anything to eat or drink until the anaesthetic wears off (around 1 hour). You should be ok to drive after the procedure.
