The delicate tissue of your vocal cords can be damaged from a number of causes: illness, surgery, chemical exposure (including cigarette smoke), violent coughing, excessive muscle tension, etc. When injured, the tissue of the mucosa covering the cords tends to stiffen as it heals, changing the sound and function of your voice. Restoration of vibratory function has variable success, depending on the extent of the injury. A recent article describes a successful attempt to grow donated vocal fold cells, which then vibrated nearly normally when implanted in dog larynges. If this technique proves out in further clinical trials, it offers a promising option for people with certain types of vocal fold damage. Click here to read more.
