The most important test is the Fibrolaryngoscopy, which consist of the insertion of a thin, flexible tube attached to a camera, into the nose, to the throat and larynx. It is a simple test which usually never requires anaesthesia and is very well tolerated, even by young children.
The vocal chords can also be inspected through a rigid tube which is inserted into the mouth, resting on the tongue (Telelaryngoscopy and Estroboscopy) and it permits us to better assess the vocal functioning.
