Background: Hoarseness due to insufficient glottal closure can be treated by injection laryngoplasty (augmentation). Vocal fold injections can be performed as an in-office procedure or under general anesthesia. As injection materials have recently improved and different injection approaches are available, injection laryngoplasties are performed much more frequently. Objectives: Advantages and disadvantages of injection materials, laryngeal approaches, and differential indications are described. Materials and methods: Literature research and experience of more than 500 laryngeal injection procedures are provided. Results and conclusions: Sophisticated use of available injection materials can provide a satisfying improvement of voice function with minimal patient discomfort. Adequate indication is mandatory for a favorable outcome. Further improvement regarding biocompatibility and the duration of injection materials is desirable. © 2015, Springer-Verlag Berlin Heidelberg.
