I did the surgery like almost 10 years ago and it did nothing but allow me to breath better. In my opinion there is no cure to stuttering because all humans have it from severe to a faint hint. What I have noticed over the years is that as your psyche ages your stutter becomes manageable perhaps this is due to the fact that you begin to value less what others think and value you more how you see yourself. If I was a teenager now I would try to learn confidence building skills because nothing will alleviate stuttering like confidence does.
