When my neurosurgeon went over the details of ACDF with me, he had explained that hoarseness is a possibilty. It's not supposed to be permanent, yet I don't recall what he may have stated that could help.

You might want to bring it to your surgeon's attention and ask for suggestions.

P.S.: When my doc told me about it, he also cited an example of how comparable effect affected one of my state's former governor's following some surgery he had.

Time, I believe, was what was needed for the fmr. governor's prob. to go away.
