Pannislectomy is basically the removal of excess skin
Abdominalplasty is tighting of the muscles with removal of abdominal skin. Here is where it gets tricky and depends on your doc, I had a pannislectomy to remove 13 plus pounds of skin and also had a hernia repair to fix the hole which also takes care of the tighting of the abdominal wall muscles at the same time. Seems all docs what to go the route of abdominalplasty because they r in bussines to make money and with insurence they will get paid at a discount rate, Always keep in mind 99% of the docs are in the plastic bussiness to make u look the best and lets face it the anchor cut is not usually used to do a pannislectomy and that can  give u a more define waist line than before and alot depends if u even had a waist going in, Take a look at my pics I had a pannislectomy and I paid 2 k for out of network for the surgery that was covered by my doc , I do not feel my doc was ripping me off and did the best possible job, He also repaired my hernia which my insurence covers in network. I also want a boob Job and I was thinking how much can i get done. I will have to go to a plastic surgeon for that but i want my doc I went to my weight loss surgeon to have my pannislectomy and I think he did a amazing job, I feel being board  certified doc in plastics  means not a whole lot   for a tummy area. My surgeon area is abdomial u know hernia gall bladder appendix weight loss surgery and he open and closes the abdominal  area all the time and I trust him 100% and he has operated on me 3 times and has done this amazing job closing me, I had emergency appendectomy when I was 12 and stab wounds from violent attack and I had these keloids which was horrible and ugly and my doc was able to remove the ugly scars and left me with a thin scar line that will fade and right now  hardly seen in some areas already. I am so shocked how well I am healing with my 36 inch cut , U can see my pics and I am still healing and I am getting a waist and I had a huge pannis more than most people. Beware of sales job when u got to plastic docs they are in bussines to make u look like barbie not a regular woman. My doc pulled up my mons area and he did not charge me for that but most plastic docs will charge you for that as well. My doc takes pride in making his  WLS pts look good after weight loss , I think my doc is the except  to most docs. He is not only my doc and partner in my weight loss Journey but feel he is a friend , cheerleader and lifestyle coach. He sees our pain and wants to do something for us. I call him mother Teresa of weight loss. LOL
