Human Adipose Tissue Derived Extracellular Matrix and Methylcellulose Hydrogels Augments and Regenerates the Paralyzed Vocal Fold - Fig 2

Abstract

<p><b>Representative serial images of high-speed camera recording at 8 weeks (A), the asymmetric index using videokymograms (B) and the results of asymmetry index for vocal functional analysis (C)</b>. (A) Normal and symmetrical vocal contacts showed no change in the vibration of vocal mucosa in sECM/MC groups relative to the control group. (B) The maximum distance in the left denervated vocal fold (<i>a</i>) was compared to the right vocal fold (<i>b</i>) using a videokymogram to generate an asymmetry index. The asymmetry index was calculated as follows: Asymmetry index = <i>a</i> / <i>b</i>. (C) The mean asymmetry index of the sECM/MC hydrogel group (1.020 ± 0.069) and the control group (0.787 ± 0.102) are shown (<i>p</i> = 0.047 using a Mann-Whitney U test). In diseased conditions, the index deviates from the value of 1.0</p
