I'm having a total tummy tuck revision will it be different than the panniculectomy that I had and what do I do different or buy to help heal up?

Different operations. A panniculectomy typically only removes skin whereas a tummy tuck will excise redundant skin and/or reposition muscles and/or the umbilicus with/without liposuction. It is typically a more involved surgery. Ok low your surgeons instructions!
Tummy tuck revision. It depends on the plastic surgeon. But a tummy tuck should be tightening the diastasis if present, more aggressive soft tissue mobilization and dog ear liposuction/ prevention. Ask about on q pain pumps for post op pain control. Http://www.mountcastleplasticsurgery.com.
