Tunicate‐Inspired Carboxymethyl Cellulose Hydrogel Filler for Treating Age‐Associated Vocal Fold Atrophy

Advanced Healthcare Materials, EarlyView.
The pyrogallol‐conjugated carboxymethylcellulose (CMC‐PG) hydrogel is applicated as a filler for the treatment of presbylaryngis, a vocal fold atrophy. CMC‐PG provides a bulking effect to the vocal folds. CMC‐PG is readily injectable and tissue adhesive, enabling sustained release of growth factor over long period.
