Ditto, I will seek voice surgery in the future too... Reason - Because with voice training alone, there is a risk of your voice cracking when under pressure (shouting, coughing, getting excited etc...) especially if you've had the same voice for so many years! (too many in my case).
Apart from that, in my case, I've been trying voice training but my voice goes croaky really quickly, if I speak quietly its certainly better. I'm using voice training app's, they're good, but the nuances of your voice are not taken into account, its right or wrong IMHO, I currently have no spare finances for F2F voice training with a professional currently, else I might be tempted to try. I think in my case that surgery is the fool proof way forward.
Its funny tho, when my voice fully broke and for a few years after I could still sing in Alto and occasionally soprano (for short periods only!)... but I let it go...
