Tt with Lip of Flanks, Back and Axillary- But What Are Flanks?

You are correct the "flanks" are your hips, love handles. Be sure you and your chosen doctor are on the same page as to terms. 

The more common name for flanks are the love handles just above the waist on a pair of jeans. Other affectionately term this a muffin top.

Liposuction of the flanks at the time of TT help narrow and contour the waist as it wraps around from the lower back to the tummy.

When you say you are ready I assume you have seen and chosen a surgeon for your tummy tuck and liposuction. This is a question you should be asking your surgeon and the answer should be in terms you can understand. If you put one finger at the bottom of your rib cage on your side and another on top of your hip bone on the side the area between your fingers is your flank. Everyone has a flank but not everyone has a love handle which is a localized excess collection of fat in the flank area.

I hope you realize that this format of posting questions and receiving answers lacks the face to face direct communication required for you to make an informed decision regarding your surgery. Most of the scar tissue that arises is formed in these areas of tissue plane separation. The same applies to breast implants where most of the scar is really around the implant.

My response to your question/post does not represent formal medical advice or constitute a doctor patient relationship. You need to consult with i.e. personally see a board certified plastic surgeon in order to receive a formal evaluation and develop a doctor patient relationship.
