Is it okay to not have a wrap after explant?

Often, these types of decisions are based on individual plastic surgeon's preference. Therefore, best to address your question directly to your plastic surgeon; ask for his/her rationale. In my practice, I also do not use "wraps";  I do use somewhat compressive dressings/bra along with drains after breast implant removal surgery. Best wishes.

 Because your surgeon used drains to close off the dead space and reduce fluid accumulation, a wrap is somewhat redundant.  Discuss with your surgeon.

We wrap the patients for the first 24 hours and then remove all dressings.  Wraps will not help, especially if you have drains.  They can affect the way the skin heals, in a negative way.
