Help. My wound keeps getting worse and worse. My doctor's office keeps saying everything is OK. What can I do? (Photo)

Hello. Great question. I am sorry for your post op difficulties. Wound dehiscence is not uncommon post tummy tuck. Keep following your surgeon's post op instructions.

Thank you for sharing your question and photographs.  Unfortunately when an incision that is under tension suffers with healing difficulties it often will get worse before it gets better.  Once the incision separates the natural tendency of the skin to recoil will make the separation worse.  Once this stabilizes your body will start filling in the area from the inside-out.  Hope this helps.

I am sorry to hear about the incision line healing problems you are experiencing.  These types of complications can be quite (understandably) distressing to patients;  unfortunately, sometimes the wounds do look worse before they begin to look better. The wounds tend to occur where incision lines come together (where there is the greatest tension and least blood supply).   In my experience, these types of incision line problems tend to "fluctuate" in appearance during the first two months after tummy tuck surgery; the vast majority of patients are fully healed by the two month postop mark.
 Sometimes removal of a exposed suture and/or removal of any unhealthy tissue will expedite healing.  There may be different treatment modalities recommended; best to "stick with" your plastic surgeons recommendations. Generally, this will involve application of some type of sterile dressing ( in my practice I use a non-stick dressing covered by a sterile dressing once a wounded is clean).  Also important to concentrate on a healthy diet, including good protein source.   Obviously, avoiding any form of nicotine is also important. 
 Although your plastic surgeon will be your best resource for definitive assessment, advice, and meaningful reassurance,  I think you can have  have peace of mind that these types of wound healing problems generally go on to heal over the course of the next several weeks, often without long-term sequelae.   In other words, unless something changes dramatically, you should be just fine long term.Best wishes.
