The Impact of Vocal Folds Augmentation with Injection Laryngoplasty on Quality of Voice in Patients with Parkinson Disease (VoCAL-PD ? Vocal Cords Augmentation Laryngoplasty in PD)

Primary Objective

1. To assess the effect of vocal folds augmentation with long acting calcium hydroxyapatite paste on the quality of voice in PD subjects. 2. To assess the effect of vocal folds augmentation with long acting calcium hydroxyapatite paste on structural and functional parameters of the larynx measured on videostroboscopic recordings assessing glottic closure time and supraglottic constriction. 3.
