These are great questions. The reason restrictions are placed after surgery is to optimize the success of the surgery during healing and to prevent complications. The most common complication after a septoplasty and turbinate reduction is a nose bleed. This can be minor, or severe enough to need to return to the OR. Forceful nose blowing can start a nose bleed. Sometimes packing has to be replaced in the nose under pressure to stop the nose bleed and this too can cause complications and affect your final result. What I ask my patients to do is to avoid nose blowing for 2 weeks after surgery. Anytime they feel the need to blow their nose I ask them to use nasal saline rinses. The saline rinses start the first day after surgery. You will have scabs and clots in your nose that will be tempting to pick, but I advise not picking at them until after you have seen your surgeon in follow up. This is because they may be attached to suture material that will cause you pain if pulled at. As for smoking, again, I would wait until after your first follow-up and discuss it with your surgeon. I see my patients at 1 week after surgery to get an idea of how things are healing and to address these concerns.
