  Update: The Cosmetic Surgery Conjecture modulo finitely many Dehn-filling
coefficients has been a well-known classical result, so the first main result
of this paper is not new. (But the author was initially unaware of this fact,
and the tools and techniques used here are very different from all the
classically known methods.) The second main result of the paper, that is, the
generalized Cosmetic Surgery Conjecture for the 2-cusped case is new, but
superseded by the author's later work.
