All versions of a tummy tuck for women aim to produce an hourglass figure. Methods to accomplish this include liposuction of the flanks and muscle repair. The term "hourglass tummy tuck" is not recognized by most plastic surgeons because it implies something different than what we already do.
Thank you for your question. A TT tightens muscles and removes skin from the abdomen. The surgeon may be describing additional liposuction to the flanks to help create contour. Liposuction to the flanks often enhances the results of a TT. Best,
