Patient | Group (vocal fold damage) | Treatment: MSC or MSC+hyaluronan (HA) (unilateral or bilateral) | Side effects: SAE (systemic reaction, airway problem, infection); minor (e.g., fold edema, laryngitis) | Age, sex | Voice Handicap Index (pre/postop 0–120) (*VHI change ≥ 13 points decrease = sign. Improvement) | Vocal fold vibration qualitative ratings (pre/postop): mucosal wave, vibration amplitude, glottal closure | Vocal fold vibration, computerized analysis (pre/postop) (normalized U) | Phonation pressure threshold: PTP (cm H2O) (pre/postop) **decrease ≥ 0.5 cm = positive change |
