Reversal of lift procedures is uncommon but does occur.  Forehead lifting, as an example, when performed too high, can be reversed to a moderate degree.  Less invasive procedures could be tried in a conservative fashion first; these would include small canula liposuction or laser lipolysis in a very conservative manner.  If this does not achieve the desired benefit, then surgical treatment could provide reduction of the asymmetry component, as well as the high cheek component.  Of course this depends on the specific anatomy and a direct examination is required before coming up with a good game plan.  Nonetheless, this is an uncommon request but not one that could not be improved upon one way or the other.
