What is an IMF tuck? What can I expect from results?

This as I also call it an inferior mastopexy is when the extra skin is removed from the breast tuck and the incision is placed along the inframammary/tuck crease. It is basically the horizontal or tuck incision only from a full lift.  This help reduce the extra skin stretch that has happened.Hope that helps.

The IMF tuck is removing the excess skin with the incision placed in the breast crease just below the breast. this is especially useful in women who have bottoming out and the implant and breast are sitting too low. It does not change the position of the nipple, but in the bottoming out categories, the nipples then look like they are back in a normal position.

You should ask your surgeon for clarification but it probably has to do with tightening the skin along the inframmamary fold where there probably is already a scar. If there is not a scar you should definitely speak to your surgeon to determine if an extra scar is worth it. It can also be accomplished from the inside of the breast.
