I think so but nothing specific. I was browsing around other websites a few months ago and ran across a report of a voice surgery in that areas of the country missing a few facts. The surgery was preformed while the patient was awake so the voice could be adjusted on the fly. From the account, the surgeon reverse engineered the surgery from a description of a another doctors procedure. The description from your link sounds like the surgery is CTA and that would match with the account that I saw on the other site. As what I saw was old, I don't know if the doctors is doing VFS now or if he is still sticking with CTA alone.
