In the laryngoscopy of fibrils, an endoscopic or esophageal endoscopic examination is performed on a fibrous tract that is attributable to a narcosis of the rhinopharyngeal region, in the region of just behind the nose. Once the nasopharynx is reached, the operator, being able to see the images coming from the tip of the instrument, was able to see a camera in an optical viewer, he was able to see correctly and completely pharynx and larynx. The examination does not require any anesthesia and is completely painless. Of the pharynx (adenoid hyperplasia, etc.) and of the nasal disturbing (rhinosinusitis, nasal obstruction of other nature).
What can be seen with a fibrolaringoscopy
The procedure allows, among other things, to accurately visualize pharynx and larynx in order to highlight all the main pathologies of these body districts. Fibrolaringoscopy is particularly indicated for the study of all types of dysphonia since it allows to observe the movement of the vocal cords while the patient emits the voice in a natural way, without the traction of the tongue by the specialist as it happens in indirect laryngoscopy (ie the classic exam with the mirror). The careful study of motility and chordal morphology is often decisive for evaluating the chances of a successful corrective logopedic treatment both in the forms of "functional dysphonia" and in the forms of "organic dysphonia".
Preparation for performing a fibrolaringoscopy.
Performing a fibrolaringoscopy does not require any specific preparation. The patient can drink and eat freely both before and after the procedure, unless, for special reasons, it is decided to perform a local anesthesia that involves the prohibition of drinking and eating within two hours following the assessment.
