I am guessing you will lose your high range. I know nothing about music, but I went from a high soprano to not being able to sing along with most pop songs on the radio! I have ZERO technical knowledge about music, but it still surprises me when I can't even raise my voice to the high level I used to use to call my dog inside, which is not nearly as high as I could sing. So no clue how low it'll drop, but I wouldn't count on being able to sing particularly high. At least that was my personal experience but, like I said, I know nothing about music.
