is there a difference between a extended tt and anchor?

I have been reading posts lately about people being really happy with the anchor cut. I am wondering if it's the same thing as the "extended" tummy tuck that my surgeon spoke to me about?

No, it's different.  I had both of those in Nov.   The anchor cut has a vertical cut as well as the usual horizontal one.  The vertical cut runs from just under the breasts and joins the horizontal cut at the bikini line or just above.  It helps eliminate the pudge above the belly button.  It gave me a great hour glass shape!
   The extended tt just has the horizontal cut but it goes further on the sides than the "regular" TT.
Hope that helps.  Good luck on your PS journey!
