I had gynecomastia surgery in 2011. i am about to undergo liposuction of the abdominals and flanks. can this further improve the looks of my chest?

No: Not unless the surgeon does anything on your chest. Liposuction of the flanks and abdomen will have no effect on the appearance of your chest. If you're still concerned with its appearance, talk to your surgeon about options for improving it, perhaps a little additional liposuction.

Unlikely: If no treatment is done to the chest, you will most likely not see any change to your gynecomastia surgery results. Speak to your surgeon and address your concerns with him for the best solution.

Probably not: You may achieve a better overall proportion to your torso but it is unlikely that it will specifically target or improve the appearance of your chest.

No but...: The planned procedure of liposuction of the abdomen and flanks will not improve the appearance of your chest. However, if you have concerns about the chest appearance, address these with your plastic surgeon; it may be that improvements can be made at the time of the planned procedures. Best wishes.

Maybe: It will improve the balance between your chest and abdomen.

Lipo changes contour: Liposuction of an area adjacent to another body part that is to undergo surgery or has had a surgical procedure usually helps create better balance of the the two areas. It will necessarily impact the chest directly. Talk to your plastic surgeon about your concerns especially if you have some uneven/asymmetric areas on your chest and s/he may be able to improve those as well for you.
