Thank you for the question. Ultimately, you will need to do your due diligence and select your plastic surgeon carefully. Then, after this careful selection, you will be best off going with his/her judgment. Generally speaking, the vast majority of patients who present for tummy tuck surgery benefit from muscle plication; as you know, this part of the tummy tuck procedure serves to re-approximate the muscles that have spread during pregnancy or weight gain/loss. Omitting this part of the procedure will potentially leave patients with continued abdominal wall laxity and, in my opinion, a less than optimal result. If you remain in doubt, seek additional consultations with well experienced board certified plastic surgeons who can demonstrate significant experience helping patients achieve the types of outcomes you would be pleased with.Best wishes.
