Can you get surgery on your vocal cords to sing higher notes?

It's not medically possible to undergo surgery to sing higher notes. The pitch of a person's singing voice is determined by feveral factors, including the length and tension of the vocal cords, as well as the size and shape of the vocal tract. While voice training and practice can help improve vocal range and control, surgical modification of the vocal cords for the sole purpose of singing higher notes is not a viable or safe option.
