However, no consistently effective treatments are currently available because of their insufficient functional recovery. RADA16\u2010I, a self\u2010assembling peptide used clinically as a hemostat, reportedly supports neurite outgrowth and functional synapse formation in vitro. The purpose of this study was to investigate the effect of RADA16\u2010I hydrogels on transected RLNs in rats.<\/jats:p><\/jats:sec><jats:sec><jats:title>Study Design<\/jats:title><jats:p>Animal experiments with controls.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Fifteen adult rats were divided into the following three groups: RADA16\u2010I (+), RADA16\u2010I (\u2212), and neurectomy. A 6\u2010mm gap of the left RLN was bridged using an 8\u2010mm silicone tube in the RADA16\u2010I (\u2212) and RADA16\u2010I (+) groups. Subsequently, RADA16\u2010I hydrogel was injected into the tube in the RADA16\u2010I (+) group. The surgical incisions were closed without any further treatment in the neurectomy group. After 8\u2009weeks, laryngoscopy and electrophysiological and histological examinations were performed to evaluate the effect of RADA16\u2010I on nerve regeneration and thyroarytenoid muscle atrophy.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Although most rats in the three groups exhibited no improvements of their vocal fold movement, partial recovery was observed in one rat in the RADA16\u2010I (+) group. The neurofilament\u2010positive areas and the number of myelinated nerves in the RADA16\u2010I (+) group were significantly higher than in the RADA16\u2010I (\u2212) group.
