Hi. I recommend for that type of surgery that my patients be off of cigarettes and all nicotine containing products for 6-8 weeks before the surgery and similar after the surgery. Smoking and nicotine significantly and negatively affect wound healing, especially for these type of surgeries where the blood supply issues are more complex. Continuing to smoke or use other nicotine containing products is placing you at a high and realistic risk of having significant wound healing problems. Honesty and transparency is key, and I would highly recommend that you be completely upfront and straightforward with your surgeon about this, and reschedule if needed.Good luck and take care,Dr. Howell
