1. Real-time tracking of vocal fold injections with optical coherence tomography

    Abstract Objectives/Hypothesis: Optical coherence tomography (OCT) is a promising new imaging modality that can help discern the layered microstructure of vocal folds. In the future, subepithelial injections of implants will improve vocal fold pliability where there is stiffness of phonatory mucosa. Using OCT both to delineate the depth of subepithelial injections real-time and to serially image the implant over time would be valuable, and has not been demonstrated previously. Study Design: Ex vivo study using excised calf larynges and survival study using canines in vivo. Methods: An investigation was done employing real-time OCT imaging of subepithelial injection pulses into ...
