History of Vocal Fold Injection

초록

The goal of vocal fold injection is to implant substance at vocal fold and restore characteristics of vocal fold oscillation without adverse reaction. After first description of vocal fold injection in 1911 by Bruening, the evolution of vocal fold injection began with a goal of filling space to achieve glottis competence with an inert material. Recent advances in injection materials and endoscopic technology have broadened the indications of vocal fold injection. Nevertheless, the current challenge is to provide a substance to maintain the space-filling without prohibiting the biomechanical and viscoelastic properties of lamina propria. Because the advances in vocal fold injection have risen from novel materials rather than new technology, the history of vocal fold injection will refer to development of materials. © Springer Nature Singapore Pte Ltd. 2021.
