Will a cleft lift give permanent cure?

You feel uncertain, correct?   I also feel uncertain as to the precise answer to your questions.   Being an 85 year old retired surgeon, no longer in practice, informened with part information from the mail, and in an evolving field where no one knows the final answer.    I have offered you sources of information.  I guess your job is to investigate until you are content, make phone calls, ask experienced docs questions and ask them to examine you and finally it is your job to decide.  My choice is to whether to tell you my guess--which on incomplete evidence is "a pretty good chance".  What alternatives do you suggest?
