Generally, is lipo suction of the flanks included in a full tummy tuck with lip or is it considered separate?

Everyone does not need liposuction of flanks with tummy tuck. In patients who need it it is an add on procedure in addition to tummy tuck. Thus there is added cost for doing extra surgery. 

Every patient is different and it depends on your findings during a physical exam. In my practice, I like people I have operated on to look as good as possible.I consider #liposuction as needed as part of a #tummy tuck. Hip/flank liposuction would be included in my quote.
