[The evaluation of voice and aerodynamic activity of larynx in patients with vocal cords atrophy]

Abstract

Atrophic changes of vocal folds may cause serious disturbances of voice quality called dysphonias. The group of 50 patients with advanced neoplasmatic disease, anorexia and elderly patients were researched. In order to assess voice quality, usual subjective diagnostic methods were used and also modern techniques of imagine of the larynx. Phonation function was examined by means of factors aerodynamic laryngeal function. The data were then analysed statistically. We found usefulness of primary, subjective examination of laryngeal phonation function in the diagnosis of vocal folds atrophy. The videolaryngostroboscopy (VLSS) allowed to distinguish clearly the organic dysphonia with the vocal folds atrophy. The evaluation of factors such as MFR, PQ, VVI showed coexistence of hypofunctional component in (phonation) in patients with the vocal folds atrophy which is important in therapy of this kind of dysphonia.
