How common is Necrosis, if you have smoked for 14 years, and I have 10 days before surgery and she said I need to stop?

Smoking can absolutely increase your risk for necrosis, wound healing problems, and infections. I don't know of any Board Certified Plastic Surgeon who does not require patients to stop smoking for at least 4 weeks prior to a tummy tuck. I find it hard to believe that your surgeon would agree to perform a tummy tuck on you 10 days from now, knowing that you are still smoking. The risks are real and well documented in the literature. You should certainly delay your surgery and perhaps you should also look for another surgeon who takes more appropriate precautions. 

Smoking brings a significant risk of cancer, stroke, heat attack, etc. From a Plastic Surgery standpoint it is a vasoconstrictor. Wound healing is all about getting oxygen and needed entities to the wound. It is well known that patients who smoke have a tremendous increase in their rate of serious complications, (infections, wounds falling apart, etc.). Nicotine is the main vasoconstrictor, so getting a patch or lozenge of nicotine won't help the vasoconstriction. Best to be off the tobacco/nicotine entirely before surgery. Please be honest with your Board Certified Plastic Surgeon. Together you can make a plan to quit and proceed with surgery. The amount of time between quitting and surgery will depend on the Plastic Surgeon and the procedure.

I always insist that any patients undergoing a tummy tuck
quit smoking for at least three months preoperatively.If you would only quit for 10 days
preoperatively, I would think that your chance of getting a necrosis is incredibly
high.I would definitely postpone your
surgery.Best of Luck.

There is a significantly higher incidence of necrosis and healing problems in smokers versus non smokers. To reduce this risk we ask our patients who smoke to stop smoking 4-6 weeks before surgery. We ask them not start again for several weeks afterwards until we are sure healing is complete. Here is the difference between a c section and a tummy tuck: In a c section, the surgeon cuts directly through the skin--there isn't any undermining or lifting up of tissues. There isn't any removal of skin. In a tummy tuck, the excess skin is removed, the adjacent skin lifted up and shifted into position to close the wound created. A tummy tuck incision relies on blood flow from the adjacent tissue to heal it. In a smoker, nicotine and by products cause the blood vessels feeding the healing incision to clamp down so the wound gets less blood flow. I would not feel comfortable proceeding with this surgery at this point.   

not only could you get skin death but your likelihood of infection, wound healing problems, dvt all go up. listen to your dr. and while you are quitting for surgery, why not quit full time.  be nice to be around for those kids who caused you to need the tummy tuck in the first -place
