The effects of cryotherapy on vocal fold healing in a rabbit model

ConclusionsCryotherapy can inhibit the inflammatory reaction and simulate a fetal healing environment in extracellular matrix synthesis to regenerate vocal fold tissue with less fibrosis. Histological results showed that cryotherapy achieves a mature healing result with less scar, which tends to return to normal. In summary, the findings of this study suggest that administration of cryotherapy at the time of injury has the potential to minimize vocal fold scarring.Level of EvidenceNALaryngoscope, 2018 (Source: The Laryngoscope)
