A Fibro Naso-Laryngoscopy Assessment on Hoarseness : Morphological Finding of the Larynx by Direct Visualization
A prospective study evaluated potential use of fibrio Naso-Laryngoscope to assess the morphology of the larynx had been conducted in patients with hoarse voice symptom, due to variable causes. Forty one subjects were examined and assessed prior to treatment to obtain the exact and definite cause of hoarseness.
