She is singing better since that surgery Charlene. The repair is more recent (2003, 04 or 05?) ...must of been 2005 since the article you found is from 2004. Last I knew she was satisfied with the results. She feels she is singing much better than before the repair and possibly even better than before the surgery she had that required the repair. This I learned about from my surgeon at MEEI when I was a patient there the same time as her. These subsequent procedures she had were more risky than the other mainly because of scar tissue. I can't seem to find a reference to the repair on the internet...but did find one from when she was looking into it.

In the article you posted...the 'plastic surgery' was performed on a priest, a surgeon and a politician to restore their speaking voice. For professional singers, I did find a reference to Tyler's surgery. Same surgeon as Andrews and also Dick Vitale.

The technology is improving all the time of course so it will be interesting to see (or hear rather) the benefits of these types of procedures in the future.
