Portage has the functionality to remove orphaned dependencies as well, but since the availability of software is dynamically dependent it is important to first update the entire system fully, including the new changes applied when changing USE flags. After this one can run  to remove the orphaned dependencies. When this is done, it might be necessary to rebuild the applications that were dynamically linked to the now-removed software titles but don't require them anymore, although recently support for this has been added to portage.
