Hello @hopeful33250 . Before this surgery I had an inyection of hyaluronic acid with success. The doctor told me that this was the next step. It is a surgery with general anestesia. They do a little "lipo" from any part of your body (in my case it was my lower stomach) to remove enough fat (1 Tablespoon is what the Dr told me she needed). Then they implant it through the mouth. I was asked to be 7 days without talking and then start talking 5 mins per hour, next day 10 min per hour and so on. I am very pleased with the results. My voice is not exactly as it was but I can have a conversation which feels wonderful. The next step would be a reconstruction of the vocal chord.
I had it done in Mayo Clinic in Jacksonville by Dr Amy Rutt. Hope this info helps...let me know if you need more info
