Morphological changes of the vocal fold mucosa in hyperfunctional dysphonia diagnosed by psychoacoustic and videostroboscopic methods

Oedema of the laryngeal mucosa confirmed by stroboscopic and ultramorphological examination may coexist with hyperfunctional dysphonia. The presence of the laryngeal oedema in patients with hyperfunctional dysphonia has the negative impact on voice quality in psychoacoustic assessment with the use of the GRBAS and YG scales.
