An endoscopy with a rigid or flexible endoscope is always performed during the exhaustive inspection of the nose and sinuses (Nasofibroscopy).
The first test is performed using mild anaesthesia with cotton swabs soaked in anaesthetic liquid or by spraying of the nostrils and it is a procedure that is very well tolerated. The second does not tend to require anaesthesia and permits us to also access and inspect the throat and vocal chords (Fibrolaringolscopy).
At times it is necessary to take nasal swabs or biopsies.
