I Had Fat Necrosis After Abdominoplasty. What Can I Do To Speed Healing and Reduce Scarring? (photo)

Your wound is very clean with a good bed of what is called granulation tissue.  Wounds heal by two processes. One is contracture which is what has to happen to bring the wound together.  Two is epithelization which occurs once the two edges of the scar are much closer together. 

Your Real Self team of plastic surgical experts agree that Regranex topical and a wound vac will speed the healing.  These are both outpatient modalities which your plastic surgeon has access to. 

Each plastic surgeon has his or her own techniques for wound healing,  What happened to you was a known complication, and retrospectively will just be a bump in the road once the wound is closed.  Stay in close contact with your plastic surgeon.  Tell him or her about your concerns.  When things go wrong, most Board Certified plastic surgeons give extra special care until things are righted.  I am sure your plastic is there for you.

Thank you for the question.

Based on the picture and description,  it sounds like your plastic surgeon is doing the right things and following you closely.  

The major principles here involve:  removal of necrotic tissue, avoidance of damage to normal healthy tissue, treatment of infection if present, removal of any foreign body that may prevent healing ( exposed sutures),  adequate nutrition/protein intake etc.

Continue to avoid the use of and/or exposure to nicotine.

Patience is indicated; it may take 2 to 4 weeks for the want to close.

Best wishes. 

Based on the photograph you provided it would appear that your wound is free of debris and on the road to healing.  The process of wound healing in a non smoker is around three months from the surgery date (over twice that for smokers).The wound should be allowed to heal on its own with just a simple gauze dressing.  All of the techniques used in wound clinics such as wound vacs and topical medications are unnecessary and tend to cause over manipulation.  This invariably slows the healing and should be reserved for problem wounds only (ie diabetic foot ulcer, etc..).The typical fallout from this complication is that a larger scar will form which can be dealt with after one year has transpired.Stay with your plastic surgeon as he or she is your best chance for an uneventful recovery.I hope this helps.
