Panniculectomy vs abdominoplasty after 100 lbs weight loss? (Photo)

These two procedures are very common but have some important differences. They both remove the redundant skin below the belly button. A tummy tuck includes tightening of the belly wall and also tightens the loose skin above the belly button (because it adjusts belly button position). Traditionally, a panniculectomy does not move the belly button.
A panniculectomy is a medical/functional surgery simply designed to remove the skin fold at the lower belly. A tummy tuck is a functional and an aesthetic surgery - it removes the lower skin fold but also has some subtle maneuvers to optimize shape, flatness and aesthetic outcome.
Both procedures would help remove the excess skin, but a tummy tuck would give the best aesthetic outcome and shape. Hope that this helps. Have a great day!
