Laryngoplasty With Hyaluronic Acid in Patients With Unilateral Vocal Fold Paralysis

A long duration (up to 12 months) of acceptable quality of voice was achieved by augmentation with Restylane, if the glottal gap was 1 mm or less videolaryngostroboscopically during phonation. The authors recommend this therapy for temporary voice improvement and to augment vocal therapy, if spontaneous recovery of voice is likely. Long-term results remain to be seen.
