Silk injection, specifically Silk Voice injection, is a procedure used to augment the size of a vocal fold that is either displaced or deformed. This augmentation aims to allow the vocal fold to meet its opposing fold at the midline, thereby improving phonation (voice production).
This procedure is particularly useful in cases of vocal fold insufficiency, which can lead to serious aspiration difficulties and require urgent intervention. The injection helps restore the vocal folds' ability to close properly, preventing food or liquids from entering the trachea (windpipe) and lungs.
In summary, silk injection is a vocal fold augmentation technique designed to improve voice and prevent aspiration by increasing the size and functionality of a compromised vocal fold.
