a Captured images of the adducted position after nerve stimulation and of the abducted position. A video clip (Video S2) of both vocal cord movement after electrical stimulation is available in the Supplementary Materials. b Relative gap ratios between vocal cords in adduction and abduction were significantly greater in the PRP-loaded NGC group (80.23 ± 6.91%) than in the non-loaded group (48.99 ± 10.71%) (P = 0.018). c Axial section of vocalis muscle: in the PRP group, muscle thicknesses were similar on left and right sides, but in the non-loaded group, left-side muscles were atrophied. d The PRP group had significant higher vocalis muscle area ratios than the non-loaded group at 12 weeks post-implantation (P = 0.033).
