Just like the title says, what are the effects of the different surgeries available on the upper range of the voice, if any?

Do the surgeries only eliminate the bottom of the range or are they also increasing the top of the range?

Results will vary but mine where totally unexpected. My trained voice before surgery was about 130-196 Hz with a best speaking voice of about 140Hz. After surgery, my range for my trained voice went to 160-500Hz with a best speaking voice of about 205Hz. Not everybody gets results like this but if your initial voice was as bad as mine was, it was worth a shot. People with better starting voices claim they lost range but I don't have good documentation to point to with numbers.

Thank you Dena.
What surgery did you have?

How do I check my range? (I tend to move to falsetto many times without noticing ^_^")
500Hz is impressive isn't it? Can you sing well?

I went to Dr Haben and have a thread I created on it. I just had the VFS as I figured the triple wouldn't give me that much more pitch. If the triple would have made it possible for me to avoid the trained voice, it would have been worth the extra money.

The voice section has a program for the PC called PRAAT which will do extensive work on a voice sample but I use PitchLab in my iPhone that allows me to check my voice when ever I want. One of these days I may put PRAAT on my system but I haven't felt the need for it yet.

I stopped singing when I turned into a bull frog. My male voice would comfortably hit 80hz and without any upper range, it was pretty well useless for singing. My voice is still in the healing stages and at this point in my life I would need to be trained to sing on key. What can I say, I sound good in the shower but then everybody does. If you have the ability to sing before surgery, you should be able to after surgery but be warned it may take a while before your voice will be stable enough to do so.

The thread I created.

My speaking voice range only changed on the lower part a bit. Mainly it is more breathy and has much less volume in the very low parts, like 90 or 100 Hz, which pre OP was still within a voice range that I could use for speaking. The top of my chest voice did not change, apparently glottoplasty cannot do that, so it is at C4 - 260 Hz in any case. But When speaking I now use head voice quite often for intonations and thats pretty normal for women to do. My head voice lost upper range. Pre OP it was going over 900 Hz, now it is hard to squeeze out anything over 700 Hz. But this upper range is something not many start out with, I guess. The comfortable speaking pitch moved from about 120-140 Hz to 160-190 Hz
