Laryngeal Liposuction
Soft tissue augmentation utilizing filler material has been used since 1893, with the German surgeon Gustov Neuber performing

fat but also calcium hydroxylapatite (Radiesse), polydimethylsiloxane (particulate silicone), and shorter acting temporary materials
such as bovine gelatin, collagen-based products, carboxymethylcellulose, hyaluronic acid (Restylane), and others. When injecting materials into vocal folds, it is important that convergence of the subglottic area be maintained
