2. 21. Reconstruction of vocal fold scarring with mesenchymal stromal cell therapy

   Author : Srinivasa Rao Nagubothu; Karolinska Institutet; Karolinska Institutet; []
   Keywords : ;

   Abstract : Tissue injury/scarring of the vocal folds (VFs) can be caused by various factors including external trauma, cancer treatment or inflammation, leading to damage within the vibrating layers and a decrease in viscoelastic functions. These effects ultimately result in severe voice problems. This condition leads to significant morbidity for patients. READ MORE
