Examination was performed 1, 3 and 6 months after injection. Results: In all cases improvement of quality of voice was obtained which was stated by a physician and the patients subjectively. Improvement of harmonic voice structure was confirmed by spectrographic record. Acoustic examinations revealed that the improvement was obtained within parameters describing frequency, amplitude disturbance and noise existence. Conclusions: Injection of the hyaluronic acid to the vocal folds improves functional phonation and quality of voice in cases of patients with glottis insufficiency.
