In Office Vocal Fold Injection Augmentation

Glottic insufficiency is a condition in which the true vocal folds, for various reasons, do not completely meet in the midline during phonation. One treatment option for this condition is vocal fold injection augmentation, in which a temporary material such as carboxymethylcellulose or hyaluronic acid is injected into the vocal fold to increase its bulk and result in closure of the glottic gap. This can be performed on an awake patient in the clinic via a transcervical or a peroral approach. The purpose of this article is to describe techniques for performing this procedure on an awake patient.
