Results from CT Scan

The results from my CT Scan were normal. There was nothing found during the scan other than a couple of cysts on my thyroid. At this point in time there is no reason they can find for my hoarseness other than my vocal chords are not closing properly. There are 3 options I have: 1) Do nothing and just live with my voice. 2) Get an injection in my vocal chord that is not working properly, this is a temporary fix and lasts about 6 months. 3) have surgery (outpatient) where the doctor makes an incision in my neck and goes in and places a hard silicon block (shaped to fit my vocal chord) so that the vocal chords will close properly. This is a permanent solution. I want to think about it and do some research first. Don't really know what I want to do at this point.
